Implement bounds check for non-sanitized value of u.m_nNewEntity.
Debug builds of the engine have an assertion, however in release these are stripped.
This fixes a full chain client RCE exploit, for more information, see: https://ctf.re/source-engine/exploitation/2021/05/01/source-engine-2/
Run all Cbuf_Execute calls in the main thread. This should fix every problem related to (but not only):
* Connecting to server while RUI dialogue is still open.
* Connecting to server while in an active game.
* Running 'weapon_reparse'.
Implement VFTable's to interface with engine (for the most part mapped out, only the new VPK methods needs further reversing).
This exposes a good majority of the FileSystem implementation of the engine, to the SDK.
Also reversed one new method: IEngine::GetPlaylistCount (gets the number of playlists read from the playlists file, the other 2 unknown methods after this one also do stuff with the playlists, but rather on KeyValues level, one checks if something exists i think, the other returns a const char. Haven't ran these yet).
Implemented StringSplit() (split string with a delimiter, and stop splitting after either the last delimiter has been reached, or nMax, so when nMax is 2, then 'SET mat_sky_color 255 255 0 255' gets split into: "SET" "mat_sky_color" "255 255 0 255").
Netconsole now sends ConVar's/ConCommands and values separately with use of StringSplit.
ConVar now uses internal ChangeStringValue (this runs the callback).
* Removed Samples button and dialogue.
* Removed SoloMesh.
* Removed TempObstacles.
* Limit 'Verts Per Poly' to 6 (DT_VERTS_PER_POLYGON).
* Moved hulldef constant and handler to TileMesh.
* Set m_tileSize based on hull (small = 32, med_short = 32, medium = 32, large = 64, extra_large = 64).
* Changing RCON passwords on the server now closes all connections and re-initializes the system.
* Fully mapped out VFTable interface for IConVar* (used for ConVar callbacks, see callback.cpp).
* Move AIN/NavMesh debug draw to ai_utility_shared.cpp.
* Use shift index + range for AIN debug draw.
* Added cvar for determining max distance between camera and tile (anything outside this range doesn't get draw).
* Pointer to g_pMemAllocSingleton
* New wrapper for returning the singleton, and creating one if not yet initialized (game shares the same pointer, and is aware of its creation).
CVEngineServer::IsPersistenceAvailable() is inline with Persistence_SetXP in S0 and S1. the virtual function never gets fired.
The approach for S0/S1 will call CVEngineServer::IsPersistenceAvailable() when Persistence_SetXP() is ran (the first function to ever use pClient->m_nPersistenceState after the SendServerInfo query).
* Move render utils to dedicated file.
* Implement more render/mesh utils.
* Added structure for OverlayTriangle_t, OverlaySweptBox_t and OverlayCapsule_t.
OverlayCapsule_t has been modified to accommodate the size in r5 (2 new vectors).
SourceSDK mathlib port with light modifications.
Renamed Vector to Vector3D (to avoid confusion with std::vector (declared as vector) and Vector2D/Vector4D).
Fixed wrong order of 'CCommandLine::ParmValue()' methods. Float overload was first, char const* last.
Added reversed members (confirmed size of 2096 bytes).
