WIP: filesystem: integrate inotify for file changes

* Despite Opus Custom have strict requirements, it's more barebones, allowing us to use maximum
frame size and custom sample rate, without resampling
* Encode each frame size to network buffer, allowing smooth voice chat even in 10 FPS
* Fix possible buffer overruns, underruns and races with platform side
* Revise all usages of offset variables, samples vs bytes

+## If you are reporting bugs
+
+1. Check you are using latest version. You can build latest Xash3D FWGS for yourself, look to README.md.
+2. Check open issues is your bug is already reported and closed issues if it reported and fixed. Don't send bug if it's already reported.
+3. Re-run engine with `-dev 2 -log` arguments, reproduce bug and post engine.log which can be found in your working directory.
+3. Describe steps to reproduce bug.
+4. Describe which OS and architecture you are using.
+6. Attach screenshot if it will help clarify the situation.
+
+## If you are contributing code
+
+### Which branch?
+
+* We recommend using `master` branch.
+
+### Third-party libraries
+
+* Philosophy of any Xash Project by Uncle Mike: don't be bloated. We follow it too.
+* Adding new library is allowed only if there is a REAL reason to use it. It's will be nice, if you will leave a possibility to remove new dependency at build-time.
+* Adding new dependencies for Waf Build System is not welcomed.
+
+### Portability level
+
+* Xash3D have it's own crt library. It's recommended to use it. It most cases it's just a wrappers around standart C library.
+* If your feature need platform-specific code, move it to `engine/platform` and try to implement to every supported OS and every supported compiler or at least leave a stubs.
+* You must put it under appopriate macro. It's a rule: Xash3D FWGS must compile everywhere. For list of platforms we support, refer to public/build.h file.
+
+### Code style
+
+* This project uses mixed Quake's and HLSDK's C/C++ code style convention. 
+* In short:
+  * Use spaces in parenthesis.
+  * Only tabs for indentation.
+  * Any brace must have it's own line.
+  * Short blocks, if statements and loops on single line are allowed.
+  * Avoid magic numbers.
+  * While macros are powerful, it's better to avoid overusing them.
+  * If you unsure, try to mimic code style from anywhere else of engine source code.
+* **ANY** commit message should start from declaring a tags, in format:
+  
+  `tag: added some bugs`
+  
+  `tag: subtag: fixed some features`
+  
+  Tags can be any: subsystem, simple feature name or even just a filename, without extension.
+  Just keep them always same, it helps keep history clean and commit messages short.

+# Bug-compatibility in Xash3D FWGS
+
+Xash3D FWGS has special mode for games that rely on original engine bugs.
+
+In this mode, we emulate the behaviour of selected functions that may help running mods relying on engine bugs, but enabling them by default may break majority of other games.
+
+At this time, we only have implemented GoldSrc bug-compatibility. It can be enabled with `-bugcomp` command line switch.
+
+## GoldSrc bug-compatibility
+
+### Emulated bugs
+
+* `pfnPEntityOfEntIndex` in GoldSrc returns NULL for last player due to incorrect player index comparison
+
+### Games and mods that require this
+
+* Counter-Strike: Condition Zero - Deleted Scenes

+## Abstract
+
+Before start, I would recommend you to compile and run engine for already supported and well-spread platform, such as GNU/Linux or Windows. Hack it, get familiar with engine.
+
+One beauties of Xash3D FWGS Engine is it modularity, so game logic, UI and renderers are located in platform-independent libraries. Every library is loaded at run time and may or may be not optional.  For example, if your platform doesn't have OpenGL of any kind, you can skip it and use our software renderer! Of course, there is no real reason to run game engine, if you don't have game logic of any kind, so the minimal build of Xash3D FWGS is headless dedicated server.
+
+Historically, Xash3D Engine was even more modular(see github.com/a1batross/Xash3D_ancient), but we thought that to fulfill our crossplatform needs we will keep all platform-specific stuff in the engine itself and libraries must import or expose platform-independent APIs.
+
+Ok, get to the point!
+
+## Porting guidelines
+
+It will not be a complete tutorial as covering everything in one article is probably just impossible. Instead, I will give you hints on how engine can be ported, how to get your port to upstreamed and how you should maintain your port.
+
+0) Get to know your platform. Maybe I asked for this lately, but you MUST KNOW YOUR PLATFORM, i.e. what's this capable of.
+
+The one of unsupported configurations at this time is when platform can't load dynamic libraries(`*.so` or DLLs). We can't help you as supporting full-static ports are violating the GPL license in various ways.
+
+The other yet unsupported configuration is the big endian.
+
+1) Setup toolchain. For dirty port, you can write Makefile for yourself, engine is written that way, so **it doesn't relies** on any generated data or any special processing. But I recommend you to use Waf anyway, it's better integrated to engine and self-documentable. Also, I will cover only our Waf build options.
+
+2) Open `public/build.h` file. Add appropriate checks for your operating system and/or CPU architecture. It shouldn't be hard.
+
+Also, you'll need to build [Half-Life SDK](https://github.com/FWGS/hlsdk-xash3d/). It has same `public/build.h` so reflect changes into it. Note that to be compatible with HLSDK proprietary license, it's relicensed as public domain under [Unlicense](https://unlicense.org).
+
+We have a library naming scheme that allows us and game creators to distribute binaries for different platforms in one archive. Read `Documentation/extensions/library-naming.md` for more information.
+
+In short, you need to call your platform in unique way. For engine side it's done in `engine/common/build.c` file in engine source code, for HLSDK side it's done in `cmake/LibraryNaming.cmake` and `scripts/waifulib/library-naming.py` files in HLSDK source code.
+
+You can use [predef project wiki](https://sourceforge.net/p/predef/wiki/Home/) for reference.
+
+2) Look at the `engine/platform` directory. We usually try to have all platform-specific stuff inside this folder.
+
+* Functions that must be available on your platform are declared in `platform.h` header. Most of them aren't used in headless dedicated build, but I will cover that later.
+
+* The POSIX-compliant(for *nix operating systems) goes into `posix` subdirectory.
+
+* The SDL-specific code goes into `sdl` subdirectory. Note that even I said before that platform-specific code is in `platform` directory, SDL obviously isn't a __platform__, so you can met checks for XASH_SDL inside whole engine, usually in input.
+
+* Custom SWAP implementation for *nix-based systems is in `swap` subdirectory. It's used when hardware may not have enough memory and you can't add swap memory. I will cover that later
+It relies on a fact that systems with paged memory will load pages into RAM and move unused to mmap()-ed by custom swap area.
+That allowed to run game engine on music player with MIPS CPU, Linux without SWAP support and
+
+* Other folders as `win32`, `android`, `linux` and so on are self-descriptive.
+
+3) As proof of concept, you can try to test that network features and dynamic library loading are implemented correctly. Build a dedicated server with XASH_DEDICATED or `--dedicated` passed  to `waf configure`.
+
+Start a server and try to connect to it from PC. If everything is fine, then you can move to next step.
+
+If you get out of memory issues, you can try Low Memory Mode, it's enabled with `--low-memory-mode=N` passed to `waf configure` where N is 1 or 2. Low Memory Mode 1 means that we will NOT break a network compatibility. 2 is deeper and doesn't guarantee protocol compatibility and available multiplayer. Of course, with Low Memory Mode 2 you can't test your port dedicated server.
+
+If you got anything compiling, it's nice time to make a commit. Commit your changes into git and push them somewhere(GitHub, GitLab or what you prefer), so you will not lose them accidentally.
+
+4) Here is most interesting, building the client part.
+
+There are three possible situations for you, by increasing difficulty.
+
+1. Do you have SDL2 for your platform? If yes, go ahead and compile engine with client part enabled.
+
+2. Do you have SDL1.2 for your platform? If yes, try to compile it, but SDL1.2 support is very limited and not tested well.
+
+3. You don't have SDL and you can't port it for some reason by yourself or SDL port just don't stable for your platform? Then you need to implement an engine backend.
+
+How to implement engine backend? Well, we have a backends system that was introduced in Old Engine. It's simply two files: backends.h and defaults.h in `common` folder in repository root. You will need to add a macros for your backends in `backends.h` and define a logic in `defaults.h`. We have already have some, check them out, as they may be handy for you.
+
+Once you did it, go back to `platform` directory and open `platform.h` headers. Create new subdirectory in `platform` folder and start implementing missing platform-specific backends one by one. I can't explain this as for obvious reasons it's too specific. You can use macros you defined before in `build.h` to check that you're compiling for your platform and `backends.h` macros to check if platform-specific backend must be enabled.
+
+As you finished, compile engine, fix errors and commit your changes and push to repository.
+
+Remember, if something doesn't work and you can't figure out why, you can join our Discord server at discord.me/fwgs. Ping me (@a1batross) or other engine developer and attach link to your repository, so we can discuss and help you in porting.

+## Console variables
+
+Console variables (or CVars) are present in all quake-based games.
+
+By default, it is settings, created by engine, server or client libraries.
+
+But you can use `set` command to define variables even if they are not created by the engine.
+
+For example, you can set cvar before it is registered in code.

+This works even in server.cfg before server cvars initialization and the engine will reuse its value on cvar creation
+
+## Aliases
+
+An alias allows to define new commands.
+
+`alias wnext "invnext;wait;wait;+attack;wait;-attack"`
+
+You can hook any command by adding an alias to it and unaliasing it, when you want to use original command.
+
+```
+alias invnext1 "unalias invnext;wnext;alias invnext invnext1"
+alias invnext invnext1
+```
+
+## Scripting extensions
+
+This is an extensions of Xash3D FWGS(merged to original Xash3D since build 3887), that can be enabled by cmd_scripting cvar.
+
+Enabling scripting: `cmd_scripting 1`
+
+This is an archive cvar and it will be saved.
+
+### CVar substitution
+
+You can substitute cvar value to any command by adding \$ symbol:
+
+`echo $sv_cheats`
+
+### Condition checking
+
+Allows checking cvar values.
+
+```
+if <value1> <operator> <value2>
+:<action1>
+:if <value3>
+::<action2>
+:<action3>
+else
+:<action4>
+```
+
+* Values are any string or numeric values (for example, substituted cvars).
+* Operator is = (or ==), \!=, \<, \>, \<=, \>=. == is same to =.
+* If single value specified, condition is true when value is non-zero
+
+Example:
+
+```
+if $sv_cheats == 1
+:echo Cheats enabled, adding cheat menu
+:exec cheatmenu.cfg
+else
+:echo Please enable cheats to use this!
+```

+## Цель
+
+На текущий момент клиенты имеют некоторые части платформозависимого кода внутри себя. Это плохо, т.к. мы не можем использовать одинаковые функции (если не перепишем почти половину кода SDL) на разных платформах.
+
+## Клиентская часть
+
+* Клиент будет иметь возможность полностью реализовать touch-ввод. Отрисовка может быть произведена через HUD.
+* Клиент получит простые события движения и обзора от движка
+
+### Клиентская реализация
+
+#### Клиент будет экспортировать некоторые функции движку (опционально):
+
+* `int IN_ClientTouchEvent ( int fingerID, float x, float y, float dx, float dy );`
+
+Вернёт 1 если касание активно, иначе 0.
+
+* `void IN_ClientMoveEvent ( float forwardmove, float sidemove );`
+
+Клиент будет накапливать значения величин для команд движения перед созданием команд и очищать их при CreateMove.
+
+* `void IN_ClientLookEvent ( float relyaw, float relpitch );`
+
+Клиент будет вращать камерой когда нужно, прямо как в реализации мыши
+
+## Движковая часть
+
+* Движок будет управлять событиями платформы и вызывать клиентские функции
+* Движок реализует стандартную систему взгляда и движения если её нет в клиенте
+
+### Движковая реализация
+
+#### События касания
+
+Перед вызовом ClientMove движок обязан получить события о касании.
+
+Если из клиента экспортирована функция IN_ClientTouchEvent, событие будет отправлено клиенту.
+
+Иначе, движок будет рисовать свой touch-интерфейс.
+
+#### Другие события
+
+Интерфейс прикосновений и код джойстика в движке будут генерировать следующие два типа событий:
+* События движения (функция IN_ClientMoveEvent)
+* События просмотра (функция IN_ClientLookEvent)
+
+Если клиент экспортирует эти функции, события будут отправляться клиенту перед CreateMove
+Иначе события просмотра будут происходить перед CreateMove, но после MoveEvent. Они будут применены к генерируемым командам

+## Purpose
+
+Clients have different platform-depended input code now.
+It is bad because we cannot use same functions (if we won't rewrite almost half of SDL) on different platforms.
+
+## Client part
+
+* Client will have ability to fully implement touch input. Drawing may be done by HUD.
+* Client will receive basic motion and look events from engine
+
+### Client implementation
+
+#### Client will optionally export some functions to Engine:
+* `int IN_ClientTouchEvent ( int fingerID, float x, float y, float dx, float dy );`
+
+Return 1 if touch is active, 0 otherwise.
+
+* `void IN_ClientMoveEvent ( float forwardmove, float sidemove );`
+
+Client wil accumulate move values before creating commands and flush it on CreateMove.
+
+* `void IN_ClientLookEvent ( float relyaw, float relpitch );`
+
+Client will rotate camera when needed as in mouse implementation
+
+## Engine part
+
+* Engine will handle platform events and call client functions.
+* Engine will implement fallback look and movement system when client interface not present
+
+### Engine implementation
+
+#### Touch events
+
+Before calling ClientMove engine must get touch events.
+
+If client exported IN_ClientTouchEvent, event will be sent to client.
+
+Otherwise engine will draw own touch interface.
+
+#### Other events
+
+Engine touch interface and joystick support code will generate two types of events:
+* Move events (IN_ClientMoveEvent function)
+* Look events (IN_ClientLookEvent function)
+
+If client exported these functions, events will be sent to client before CreateMove
+Otherwise Look Event will be processed before CreateMove, but MoveEvent after. It will be applied to generated command

+I propose a new library naming scheme, which will allow to distribute mods and games in single archive to different operating systems and CPUs:
+
+Legend:
+* $os -- Q_buildos() return value, in lower case.
+* $arch -- Q_buildarch() return value, in lower case.
+* $ext -- OS-specific extension: dll, so, dylib, etc.
+
+The scheme will be:
+
+1. Client library:
+* ```client.$ext``` for **Win/Lin/Mac** with **x86**.
+* ```client_$arch.$ext``` for **Win/Lin/Mac** with **NON-x86**.
+* ```client_$os_$arch.$ext``` for everything else.
+
+2. Menu library:
+* ```menu.$ext``` for **Win/Lin/Mac** with **x86**.
+* ```menu_$arch.$ext``` for **Win/Lin/Mac** with **NON-x86**.
+* ```menu_$os_$arch.$ext``` for everything else.
+
+3. Server library:
+* On  **Win/Lin/Mac** with **x86**, it **MUST** use the raw gamedll name for corresponding OS field from `gameinfo.txt`.
+* On **Win/Lin/Mac** with **NON-x86**, it **MUST** use the raw gamedll name for corresponding OS field from `gameinfo.txt`, but append ```_$arch``` before file extension. Like: ```hl_amd64.so``` or ```cs_e2k.so```.
+* On everything else, it must use gamedll name from ```gamedll_linux``` field, but append ```_$os_$arch``` before file extension. Like: ```hl_haiku_amd64.so``` or ```cs_freebsd_armhf.so```.
+Why ```gamedll_linux``` and not ```gamedll```? Because it looks more logic that way, most operating systems are *nix-like and share code with Linux, rather than Windows.
+
+4. Refresh library: not needed, as RefAPI is not stable and it's not intended to distribute with mods.
+
+For any libraries distributed **with** engine, naming scheme should be used more convenient for OS port.
+
+Issue #0. Inconsistency between ABI and Q_buildarch.\
+Resolution: Change Q_buildarch return value to use Debian-styled architectures list: https://www.debian.org/ports/, which includes a special naming for big/little-endian and hard/soft-float ARM.
+
+Issue #1: Build-system integration.\
+Resolution: implemented as [LibraryNaming.cmake](https://github.com/FWGS/hlsdk-xash3d/blob/master/cmake/LibraryNaming.cmake) and [library_naming.py](https://github.com/FWGS/hlsdk-xash3d/blob/master/scripts/waifulib/library_naming.py) extensions, see 
+
+Issue #2(related to #0): Which ARM flavours we actually need to handle?\
+Resolution: Little-endian only, as there is no known big-endian ARM platforms in the wild.
+Architecture is coded this way:
+* ```armvxy```, where `x` is ARM instruction set level and `y` is hard-float ABI presence: `hf` where hard float ABI used, otherwise `l`.

+# Server porting
+Original valve's server code was compatible with linux and gcc 2.x.
+Newer gcc versions have restriction which breaks build.
+Now, to make it building with gcc 4.x, you need do following:
+* Go to cbase.h and redefine macros as following
+```
+#define SetThink( a ) m_pfnThink = static_cast <void (CBaseEntity::*)(void)> (&a)
+#define SetTouch( a ) m_pfnTouch = static_cast <void (CBaseEntity::*)(CBaseEntity *)> (&a)
+#define SetUse( a ) m_pfnUse = static_cast <void (CBaseEntity::*)( CBaseEntity *pActivator, CBaseEntity *pCaller, USE_TYPE useType, float value )> (&a)
+#define SetBlocked( a ) m_pfnBlocked = static_cast <void (CBaseEntity::*)(CBaseEntity *)> (&a)
+#define ResetThink( ) m_pfnThink = static_cast <void (CBaseEntity::*)(void)> (NULL)
+#define ResetTouch( ) m_pfnTouch = static_cast <void (CBaseEntity::*)(CBaseEntity *)> (NULL)
+#define ResetUse( ) m_pfnUse = static_cast <void (CBaseEntity::*)( CBaseEntity *pActivator, CBaseEntity *pCaller, USE_TYPE useType, float value )> (NULL)
+#define ResetBlocked( ) m_pfnBlocked = static_cast <void (CBaseEntity::*)(CBaseEntity *)> (NULL)
+...
+#define SetMoveDone( a ) m_pfnCallWhenMoveDone = static_cast <void (CBaseToggle::*)(void)> (&a)
+```
+* Replace all SetThink(NULL), SetTouch(NULL), setUse(NULL) and SetBlocked(NULL) by ResetThink(), ResetTouch(), ResetUse() and ResetBlocked()
+* Sometimes you may need to add #include <ctype.h> if functions tolower or isspace are missing
+
+# Client porting
+
+## VGUI library
+
+Valve's client uses vgui library which is available only on x86 systems and has big amount of mistakes in headers. The best and simplest way of porting is removing VGUI dependency at all.
+Most singleplayer mods don't really use VGUI at all. It is used in multiplayer only to show score table and MOTD window
+
+## Porting 
+
+### First strategy: full port
+
+#### Basic port (Stage 1)
+* First, remove all files and headers which use vgui (contains "vgui" in file name).
+* After that, try to build it and remove vgui includes.
+* Remove all gViewPort usings.
+* Remove all CVoiceManager usings (xash3d does not support voice)
+* Redefine all DLLEXPORT defines as empty field (Place it under _WIN32 macro if you want to keep windows compatibility).
+* Remove hud_servers.cpp and Servers_Init/Servers_Shutdown from hud.cpp
+* Fix CAPS filenames in includes (like STDIO.H, replace by stdio.h).
+* Replace broken macros as DECLARE_MESSAGE, DECLARE_COMMAND by fixed examples from our hlsdk-xash3d port (cl_util.h)
+* Add ctype.h where it is need (tolower, isspace functions)
+* Add string.h where it is need (memcpy, strcpy, etc)
+* Use in_defs.h from hlsdk_client
+* Add scoreboard_stub.cpp and input_stub.cpp from hlsdk-xash3d to fix linking.
+Now your client should be able to build and work correctly. Add input_xash3d.cpp from hlsdk-xash3d project to fix input.
+
+#### Multiplayer fix (Stage 2)
+Look at hlsdk-xash3d project.
+
+Main changes are:
+* Add MOTD.cpp, scoreboard.cpp and input_xash3d.cpp
+* Add missing functions to hud_redraw.cpp, hud.cpp and tri.cpp, fix class defination in hud.h
+* Remove duplicate functions from hud.cpp and HOOK_MESSAGE's for it
+* Remove +showscores/-showscores hooks from input.h
+* Fix cl_util.h
+
+### Second way: move mod to hlsdk-xash3d
+Look at changes you made in client.
+
+If there are not much changes (for example, only some weapons was add), add these changes in hlsdk-xash3d.
+
+You may use diff with original HLSDK you used and apply it as patch to hlsdk-xash3d.
+
+Files must have same line endings (use dos2unix on all files).
+
+I recommend to enable ignoring space changes in diff.
+### Writing Makefiles
+
+Use Makefile from hlsdk-xash3d as Makefile example.
+
+Get .c and .cpp file lists from Visual Studio project and fill SRCS and SRCS_C variables to Makefile.
+
+Remove all files containing vgui in name from list, add missing include dirs.
+
+Do same for Android.mk if you are building for android.

+As online community is growing, we don't want to keep bad or invalid servers on the Internet Games list. It's a common rules for all Xash3D server owners who are using default master server. 
+
+1. Breaking master server or clients is prohibited in any way. If you found a serious bug, contact us at contact 'at' fwgs.ru or post an issue at GitHub.
+
+2. Changing settings, exploiting vulnerabilities of clients is prohibited in any way. If you found a serious bug, contact us at contact 'at' fwgs.ru or post an issue at GitHub.
+
+2. Agressive advertisement and spam on other servers is prohibited in any way.
+
+3. If your server is require downloading custom content, it should be available for everyone. Recommended way to deliver custom content is FastDL.
+
+4. It's recommended to keep your server is up-to-date. You may use our public Debian/Ubuntu/Arch Linux [repository](https://github.com/FWGS/xash3d/wiki/How-to-set-up-a-Xash3D-Dedicated-Server-on-Debian-or-Ubuntu) to simplify updating process.
+
+Just follow these rules to not get banned on our master server. Good luck, have fun!

+
+Xash3D FWGS is a fork of Xash3D Engine by Unkle Mike with extended features and crossplatform.
+
+```
+Xash3D is a game engine, aimed to provide compatibility with Half-Life Engine, 
+as well as to give game developers well known workflow and extend it.
+Read more about Xash3D on ModDB: https://www.moddb.com/engines/xash3d-engine
+```
+
+## Fork features
+* HLSDK 2.4 support.
+* Crossplatform: supported x86 and ARM on Windows/Linux/BSD/Android. ([see docs for more info](Documentation/ports.md))
+* Modern compilers support: say no more to MSVC6.
+* Better multiplayer support: multiple master servers, headless dedicated server.
+* Mobility API: allows better game integration on mobile devices(vibration, touch controls)
+* Different input methods: touch, gamepad and classic mouse & keyboard.
+* TrueType font rendering, as a part of mainui_cpp.
+* Multiple renderers support: OpenGL, GLESv1, GLESv2, Software
+* A set of small improvements, without broken compatibility.
+
+## Planned fork features
+* Virtual Reality support and game API
+* Voice support
+* Vulkan renderer
+
+## Installation & Running
+0) Get Xash3D FWGS binaries: you can use [testing](https://github.com/FWGS/xash3d-fwgs/releases/tag/continuous) build or you can compile engine from source code.
+1) Copy engine binaries to some directory.
+2) Copy `valve` directory from [Half-Life](https://store.steampowered.com/app/70/HalfLife/) to directory with engine binaries.
+If your CPU is NOT x86 compatible or you're running 64-bit version of the engine, you may want to compile [Half-Life SDK](https://github.com/FWGS/hlsdk-xash3d).
+This repository contains our fork of HLSDK and restored source code for some of the mods. Not all of them, of course.
+You still needed to copy `valve` directory as all game resources located there.
+3) Run the main executable (`xash3d.exe` or AppImage).
+
+For additional info, run Xash3D with `-help` command line key.
+
+## Contributing
+* Before sending an issue, check if someone already reported your issue. Make sure you're following "How To Ask Questions The Smart Way" guide by Eric Steven Raymond. Read more: http://www.catb.org/~esr/faqs/smart-questions.html
+* Issues are accepted in both English and Russian
+* Before sending a PR, check if you followed our contribution guide in CONTRIBUTING.md file.
+
+## Build instructions
+We are using Waf build system. If you have some Waf-related questions, I recommend you to read https://waf.io/book/
+
+NOTE: NEVER USE GitHub's ZIP ARCHIVES. GitHub doesn't include external dependencies we're using!
+
+### Prerequisites
+
+If your CPU is x86 compatible, we are building 32-bit code by default. This was dont for keeping compatibility with Steam releases of Half-Life and based on it's engine games.
+Even if Xash3D FWGS does support targetting 64-bit, you can't load games without recompiling them from source code!
+
+If your CPU is NOT x86 compatible or you decided build 64-bit version of engine, you may want to compile [Half-Life SDK](https://github.com/FWGS/hlsdk-xash3d).
+This repository contains our fork of HLSDK and restored source code for some of the mods. Not all of them, of course.
+
+#### Windows (Visual Studio)
+* Install Visual Studio.
+* Install latest [Python](https://python.org) **OR** run `cinst python.install` if you have Chocolatey.
+* Install latest [Git](https://git-scm.com/download/win) **OR** run `cinst git.install` if you have Chocolatey.
+* Download [SDL2](https://libsdl.org/download-2.0.php) development package for Visual Studio.
+* Clone this repository: `git clone --recursive https://github.com/FWGS/xash3d-fwgs`.
+* Make sure you have at least 12GB of free space to store all build-time dependencies: ~10GB for Visual Studio, 300 MB for Git, 100 MB for Python and other.
+
+#### GNU/Linux
+##### Debian/Ubuntu
+* Enable i386 on your system, if you're compiling 32-bit engine on amd64. If not, skip this
+
+`$ sudo dpkg --add-architecture i386`
+* Install development tools
+  * For 32-bit engine on amd64: \
+    `$ sudo apt install build-essential gcc-multilib g++-multilib python libsdl2-dev:i386 libfontconfig-dev:i386 libfreetype6-dev:i386`
+  * For everything else: \
+    `$ sudo apt install build-essential python libsdl2-dev libfontconfig-dev libfreetype6-dev`
+* Clone this repostory:
+`$ git clone --recursive https://github.com/FWGS/xash3d-fwgs`
+
+### Building
+#### Windows (Visual Studio)
+0) Open command line
+1) Navigate to `xash3d-fwgs` directory.
+2) Carefully examine which build options are available: `waf --help`
+3) Configure build: `waf configure -T release --sdl2=c:/path/to/SDL2`
+4) Compile: `waf build`
+5) Install: `waf install --destdir=c:/path/to/any/output/directory`
+
+#### Linux
+If compiling 32-bit on amd64, you may need to supply `export PKG_CONFIG_PATH=/usr/lib/i386-linux-gnu/pkgconfig` prior to running configure.
+
+0) Examine which build options are available: `./waf --help`
+1) Configure build: `./waf configure -T release`
+(You need to pass `-8` to compile 64-bit engine on 64-bit x86 processor)
+2) Compile: `./waf build`
+3) Install(optional): `./waf install --destdir=/path/to/any/output/directory`

+# Building
+
+## Manual build (without CMake)
+
+### Building engine
+
+Clone Xash3D repository using git:
+
+    git clone https://github.com/FWGS/xash3d
+
+Move to the Xash3D folder:
+
+    cd xash3d/engine
+
+    make -f Makefile.linux XASH_VGUI=1
+
+or same for dedicated
+
+    make -f Makefile.linux XASH_DEDICATED=1
+
+To enable dll support on linux, build loader library:
+
+    cd ../loader
+    make -f Makefile.linux libloader.so libloader.a
+    cp libloader.so libloader.a ../engine/
+
+And built engine with XASH_DLL_LOADER=1:
+
+    cd ../engine
+    make -f Makefile.linux XASH_VGUI=1 XASH_SDL=1 XASH_DLL_LOADER=1
+
+or same for dedicated server
+
+    cd ../engine
+    make -f Makefile.linux XASH_DEDICATED=1 XASH_DLL_LOADER=1
+
+### Building engine in separate library
+
+Some old distros does not support hidden symbol visibility
+This results in crash when loading server library
+
+Building launch binary
+
+    cd (xash3d)/game_launch
+    gcc xash.c -o xash -ldl -lrt -lm
+
+Building engine library:
+
+    make -f Makefile.linux XASH_SINGLE_BINARY=0
+
+## Building on Windows
+
+### Visual Studio 2013 (recommended for Windows)
+
+Download latest prebuilt SDL2 from
+
+https://www.libsdl.org/release/SDL2-devel-2.0.4-VC.zip
+
+Unzip and rename `SDL2-2.0.4` folder to `SDL2` and put it next to xash3d project folder.
+
+    ..\xash3d\
+    ..\SDL2\
+
+Open `xash.sln` with Visual Studio 2013 and make a build. After building, copy contents of `Debug` or
+`Release` folder to directory you choose. Copy `valve` folder and `vgui.dll` from your Half Life game
+installation folder and `SDL2.dll` form `\SDL2\lib\x86\` to it.
+Move `vgui_support.dll` into `valve` folder.
+
+    ..\valve\
+    ..\valve\vgui_support.dll
+    ..\menu.dll
+    ..\SDL2.dll
+    ..\vgui.dll
+    ..\xash.dll
+    ..\xash.exe
+
+Now you good to go, just run `xash.exe`.
+
+### Visual Studio 6
+
+This is legacy configuration, but msvc6 seems to generate more stable and more effective code
+
+Setup your msvc6 enviroment, unpack SDL2-2.0.4 to xash3d folder and do:
+
+    cd (xash3d)\engine
+    ..\msvc6\build.bat
+    cd (xash3d)\game_launch
+    ..\msvc6\build_launch.bat
+
+### MinGW
+
+The most effective configuration, but maybe unstable.
+Setup your MinGW environment and run:
+
+    cd (xash3d)\engine\
+    CC=gcc mingw32-make -f Makefile.mingw
+
+    engine will be built to single exe binary
+
+## Building game mods
+
+### Linux
+
+#### microndk
+
+All mods that ported to android may be build to linux using Android.mk with microndk:
+
+[https://github.com/SDLash3D/microndk]
+
+Clone microndk repo somewhere, change xash3d_config to preffered configuration (change arch to x86
+for example)
+
+Go to dlls folder if you are building server or cl_dlls if you are building client and do:
+
+    make -f /path/to/microndk/microndk.mk -j4
+
+Do:
+
+    make -f /path/to/microndk/microndk.mk -j4 clean
+
+every time when you build client after building server
+
+#### Makefile.linux
+
+### Windows
+
+On windows common way is using Visual Studio as many mods does not correctly work with mingw.
+
+Just open project and build it.
+
+Other is using mingw and microndk, but it was not tested yet.
+
+hlsdk-xash3d based mods may work fine with mingw.
+
+You may use microndk to build it. Build process is very similar to linux one.
+
+After setting up MinGW enviroment, do:<br>
+`mingw32-make -f \path\to\microndk\Microndk.mk`
+
+to build 64-bit library, use:<br>
+`mingw32-make -f \path\to\microndk\Microndk.mk 64BIT=1`
+
+Edit xash3d_config.mk to set optimal CFLAGS if you are running server
+
+# Running
+
+Copy **valve** folder from Half-Life:
+
+    cp -r $HOME/.steam/steam/steamapps/common/Half-Life/valve $HOME/Games/Xash3D
+
+**NOTE**: If you build with CMake, you can now use `make install`. It will install binaries where
+they must be located. So just run `xash3d` from command line in directory where is gamedata is located.
+For additional info look to the CMakeLists.txt in repo root and xash3d.sh script.
+
+After a successful build, copy the next files to some other directory where you want to run Xash3D:
+
+    cp engine/libxash.so game_launch/xash3d mainui/libxashmenu.so $HOME/Games/Xash3D
+
+If you built it with XASH_VGUI, also copy vgui.so:
+
+    cp ../hlsdk/linux/vgui.so vgui_support/libvgui_support.so $HOME/Games/Xash3D
+
+Copy script:
+
+    cp ../xash3d.sh $HOME/Games/Xash3D
+
+Run:
+
+    cd $HOME/Games/Xash3D
+    ./xash3d.sh
+
+## Manual running
+
+Put xash3d binaries and vgui(optionally) to you game data directory and run:
+
+    LD_LIBRARY_PATH=. ./xash -dev 5
+
+## Running under GDB
+
+    LD_LIBRARY_PATH=. gdb --args ./xash -dev 5
+
+## Using DLL Loader
+
+Put vgui_support.dll from windows build to your game data folder and run:
+
+    LD_LIBRARY_PATH=. ./xash -dev 5 -vguilib vgui.dll -clientlib valve/cl_dlls/client.dll -dll dlls/hl.dll
+
+## Running MinGW builds
+
+Put exe file to your game data directory
+
+    cd (game)\
+    xash_bin -dev 5
+
+### Running MinGW builds under GDB
+
+    gdb --args ./xash_bin.exe -dev 5
+
+# Useful GDB commands
