wscript: add yy-thunks library to help support the holy cow of windows users

This is an annoying message that's caused by the game code. Decals, without
custom renderer, cannot be rendered on non-brush entities, and everybody knows
that anyway.

+## Lightmapped water
+
+Xash3D FWGS supports lightmapped water, as an extension. It adds three new cvars and new worldspawn key values.
+
+### For level designers:
+
+If you're a level designer and intend to make your level to have lightmapped water, you can put these keyvalues to worldspawn entity description (always first entity in entities list):
+
+| Key                    | Value   | Description |
+| ---------------------- | ------- | ----------- |
+| `_litwater`            | integer | Set to any non-zero value to enable lightmapped water. Overrides `gl_litwater_force` cvar value. |
+| `_litwater_minlight`   | integer | Minimal lightmap value water surface will receive. Helps to avoid too dark areas when water isn't properly lit. If not set, defaults to zero. |
+| `_litwater_scale`      | float   | Scales up lightmap value for water surfaces. If not set, defaults to 1.0. |
+
+### For players:
+
+Some of the maps already have computed lightmap for water surfaces and sometimes water has been properly lit but the support hasn't been declared by the level designer.
+
+As a player, you can enable it in `Video options` menu or through console with `gl_litwater_force` cvar. There are also `gl_litwater_minlight` and `gl_litwater_scale` cvars that function similar to keys above. The default values has been set to `192` and `1.25` respectively to slightly avoid issues with maps that wasn't intended to have lightmapped water.

+However, here comes the broker, by running it (in trusted
+network, preferrably) on a machine that has Steam client installed, the
+engine can communicate with it, acquiring needed information to log-in into
+Steam protected multiplayer servers.
+
+## Key Characteristics
+
+Broker uses a simple TCP-based binary protocol with the following properties:
+
+- Single active session per connection: once a session is activated, the broker will reject all other TCP connections until the session is terminated.
+- All messages follow a consistent structure with a header, length, and payload: this is called a "frame".
+- Stateful interactions: commands affect the session state, and certain commands are only valid in specific states.
+- Numeric parameters are encoded in little-endian format for compatibility with majority of platforms.
+---
+
+## Frame Format
+
+All communication uses a fixed frame structure:
+
+| Field | Size | Type | Description |
+|-------|------|------|-------------|
+| Header | 4 bytes | ASCII | Frame start signature |
+| Length | 2 bytes | uint16_t (LE) | Size of payload in bytes |
+| Payload | N bytes | Binary | Command string or response data |
+
+**Notes**:
+- Header must be exactly `SBRK` (`53 42 52 4B` in hexadecimal form)
+- Maximum frame size: soft limit is 4096 bytes, hard limit is 65535 bytes (due to uint16_t usage)
+
+---
+
+## Session Lifecycle
+
+```
+┌──────────────┐
+│     IDLE     │ ← Initial state, accepts new TCP connections
+└──────────────┘
+       │ sb_gamedir
+       ↓

+# XRCON Protocol Specification
+
+## Overview
+
+XRCON is a TCP-based remote console protocol implemented as a server within the engine. It provides an alternative to the legacy RCON (which operates over UDP as out-of-band packets). XRCON uses a framed binary protocol over a single persistent TCP connection, accepting at most one client at a time.
+
+Key characteristics:
+
+- Based on TCP (stream-oriented, reliable)
+- Default port is 27000
+- Maximum only one concurrent client
+- Binary framed protocol with a 12-byte header + variable-length payload
+
+
+
+## Configuration
+
+The XRCON server is controlled by two configuration variables, both restricted to privileged users:
+
+| Variable | Default | Description |
+|---|---|---|
+| `xrcon_enable` | `0` (disabled) | Master switch; when enabled, the server starts listening for connections |
+| `xrcon_address` | `127.0.0.1:27000` | Bind address and port; supports both IPv4 and IPv6. Changing this at runtime triggers a XRCON server restart (stop + rebind) |
+
+By default, XRCON binds only to localhost (`127.0.0.1`), providing a degree of access control. The server will not start listening until explicitly enabled.
+
+
+
+## Frame Format
+
+All XRCON messages are encapsulated in a framed binary format. Each frame consists of a fixed 12-byte header followed by a variable-length payload.
+
+### Header (12 bytes)
+
+| Offset | Size | Field | Description |
+|---|---|---|---|
+| 0 | 4 | Type | 4-character message type string (null-terminated, occupies 5 bytes in the structure but the 5th byte is padding) |
+| 4 | 4 | Version | Protocol version (32-bit unsigned integer, network byte order) |
+| 8 | 2 | Length | Total frame length in bytes, including the header (16-bit unsigned integer, network byte order) |
+| 10 | 2 | Handle | Handle or sequence number (16-bit unsigned integer, network byte order; currently always zero) |
+
+
+### Protocol Version
+
+The current protocol version is `0x000000D4` (212 decimal). The server also accepts `0x00D40000` for compatibility with certain third-party clients (e.g., CS2RemoteConsole).
+
+### Maximum Frame Size
+
+- Maximum payload per frame: 4096 bytes
+- Maximum total packet size (header + payload): approximately 4136 bytes
+- Receive buffer size: 4096 + 64 bytes
+- Transmit buffer size: 16384 bytes (4 × maximum frame size)
+
+### Byte Order
+
+Multi-byte integer fields (version, length, handle) are transmitted in **network byte order** (big-endian).
+
+
+
+## Message Types
+
+| Type | Direction | Description |
+|---|---|---|
+| `CMND` | Client → Server | Execute a console command |
+| `PRNT` | Server → Client | Console output / print message |
+| `CHAN` | Server → Client | Channel list (channel metadata) |
+| `AINF` | Server → Client | Application / server info |
+| `ADON` | Server → Client | Additional info / server name |
+
+### CMND — Client Command
+
+**Direction**: Client → Server
+
+Sent by the client to execute a console command on the server.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"CMND"`, version, length, handle |
+| Payload | Variable | Raw command string (null-terminated) |
+
+The command string is injected into the engine's command buffer for execution. There is **no authentication** — any connected client may execute arbitrary commands.
+
+### PRNT — Server Print
+
+**Direction**: Server → Client
+
+Sent by the server to stream console output to the connected client.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"PRNT"`, version, length, handle |
+| Channel ID | 4 bytes | Channel identifier (unsigned 32-bit integer; always 0 for "Console") |
+| Padding | 20 bytes | Reserved (5 × 32-bit unsigned integers, all zero) |
+| Red | 1 byte | Red color component (always 255) |
+| Green | 1 byte | Green color component (always 255) |
+| Blue | 1 byte | Blue color component (always 255) |
+| Alpha | 1 byte | Alpha / opacity component (always 255) |
+| Text | Variable | The console output text (up to 4096 bytes) |
+
+
+### CHAN — Channel List
+
+**Direction**: Server → Client
+
+Sent by the server during the initial handshake (and potentially later) to describe the available console output channels.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"CHAN"`, version, length, handle |
+| Channel Count | 2 bytes | Number of channel records (unsigned 16-bit integer; always 1) |
+
+Each channel record (58 bytes):
+
+| Field | Size | Description |
+|---|---|---|
+| Channel ID | 4 bytes | Unique channel identifier (unsigned 32-bit integer; always 0) |
+| Unknown 1 | 4 bytes | Reserved (unsigned 32-bit integer; always 0) |
+| Unknown 2 | 4 bytes | Reserved (unsigned 32-bit integer; always 0) |
+| Default Verbosity | 4 bytes | Default verbosity level (unsigned 32-bit integer; always 5) |
+| Current Verbosity | 4 bytes | Current verbosity level (unsigned 32-bit integer; always 5) |
+| Red | 1 byte | Red color component for the channel (always 255) |
+| Green | 1 byte | Green color component (always 255) |
+| Blue | 1 byte | Blue color component (always 255) |
+| Alpha | 1 byte | Alpha component (always 255) |
+| Name | 34 bytes | Channel name string, null-padded (always `"Console"`) |
+
+Total payload size for this frame: 2 + 58 = 60 bytes.
+
+### AINF — Application Info
+
+**Direction**: Server → Client
+
+Sent by the server immediately after a client connects, before `ADON` and `CHAN`.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"AINF"`, version, length, handle |
+| Payload | 77 bytes | All zeros (placeholder / reserved for structured application information) |
+
+This packet currently serves as a placeholder and contains no meaningful data. It may be extended in future versions to carry structured metadata about the server application.
+
+### ADON — Additional Info
+
+**Direction**: Server → Client
+
+Sent by the server immediately after `AINF` during the connection handshake.
+
+| Section | Size | Description |
+|---|---|---|
+| Header | 12 bytes | Type = `"ADON"`, version, length, handle |
+| Unknown | 2 bytes | Reserved (unsigned 16-bit integer; always 0) |
+| Name Length | 2 bytes | Length of the name string (unsigned 16-bit integer) |
+| Name | Variable | Server name / identifier string (e.g., `"HLDS"`) |
+
+This packet carries the server application name, which is a short string identifying the server type (e.g., `"HLDS"` for Half-Life Dedicated Server).
+
+
+
+## Security
+
+XRCON has **no built-in authentication or encryption**. There is no password validation or transport-layer security. Any client that can establish a TCP connection to the XRCON port has full command execution access to the engine console.
+
+The only security measures are:
+
+1. **Default localhost binding**: The server binds to `127.0.0.1` by default, accepting connections only from the local machine.
+2. **Disabled by default**: The `xrcon_enable` variable defaults to `0`, so the server does not listen unless explicitly enabled.
+3. **Privileged variables**: Both configuration variables are restricted to privileged users and cannot be modified through unprivileged console commands or external access.
+
+
+
+## Comparison with Legacy RCON
+
+| Feature | XRCON | Legacy RCON |
+|---|---|---|
+| Transport | TCP (stream) | UDP (datagram, out-of-band) |
+| Port | Configurable, default 27000 | Game port (default 27015) |
+| Framing | Binary frame header | Plain text over UDP |
+| Authentication | None | Password-based |
+| Max clients | 1 | Multiple |
+| Interaction format | Full console access | Request-response only for submitted command |
+| Supported environments | Client and server | Server only |

+# Static HTTP server list
+
+Replacement for the UDP `S2M_SCAN_REQUEST` / `M2A_SERVERSLIST` exchange
+described in [02-connectionless.md](02-connectionless.md). Read-only HTTP,
+no NAT punching, no filtering or pagination in the request.
+
+## URL
+
+`xashcomm.lst` carries a base URL per source:
+
+```
+masterstatic http://master.example.org/server-list
+```
+
+The engine appends `/v1/servers/<gamedir>` and `GET`s the result. For
+`gamedir = valve`:
+
+```
+GET http://master.example.org/server-list/v1/servers/valve
+```
+
+Trailing slashes on the base URL are stripped. Multiple `masterstatic`
+lines are allowed; results are merged.
+
+The request is bare: no body, no auth, no cookies, no compressed encodings.
+Only the standard `User-Agent` is set. `POST` / `PUT` / `DELETE` are not
+used; servers register out of band.
+
+## Response
+
+UTF-8 text, parsed line by line. Each line is tokenized with
+`COM_ParseFileSafe` (whitespace separates, `//` and `#` start line
+comments, `"..."` quotes a token). Blank lines and comment-only lines
+are ignored. One directive per line:
+
+* `ip <address>` — Xash3D server (protocol 49).
+* `gs <address>` — GoldSrc server (protocol 48).
+
+`<address>` is parsed by `NET_StringToAdr` (`1.2.3.4:27015`,
+`[2001:db8::1]:27015`, hostnames). Port defaults to `27015`. Lines
+starting with an unknown directive are skipped entirely, so new keywords
+with any number of operands can be added without breaking older clients.
+
+`Content-Type` is not inspected, `text/plain; charset=utf-8` expected.
+
+### Example
+
+```
+# diffusion servers
+ip 192.0.2.10:27015
+ip [2001:db8::1]:27015
+gs 198.51.100.5:27015
+```
+
+A file with zero records is valid and represents an empty list.
+
+### Versioning
+
+The `/v1/` segment is fixed in this revision. A future protocol revision
+adds a sibling `/v2/...` resource without breaking older clients.
+
+## Client behaviour
+
+Each `ip` / `gs` record from the response triggers a probe to the listed
+address, identical to a server discovered through the UDP master. DNS
+errors, non-200 responses, and malformed bodies are reported to the
+console.
+
+## Server behaviour
+
+Any static HTTP server works. A typical setup is a periodic job that
+probes a set of known addresses and writes `v1/servers/<gamedir>`.
