Rebuilds SV_BroadcastVoiceData with an additional check of "sv_alltalk" cvar to disable team checking, allowing for servers to enable global voice chat
* Decoding and encoding is done into a single buffer, from raw buffers to avoid extraneous copies.
* Added base class holding all core logic for encoding, decoding, receiving and processing of the RCON protocol. This code was initially identical between all implementations of RCON, deduplicating this avoids bugs.
* Added more sophisticated error handling, stop right away when decoding for example fails.
* Added ability to have more than one active authenticated net console on the server. Controlled by cvar 'sv_rcon_maxconnections' (default 1).
* Max packet size for accepted, but not authenticated sockets is now controled by cvar 'sv_rcon_maxpacketsize' (default 1024).
* Fixed 'connect' socket bug preventing connection to IPv4 addresses, by making the method used by the listen socket and connect socket configurator shared (dual stack was disabled on connect, but not on listen).
* Removed extraneous member from the 'CSocketCreator' class, this member was a copy of the 'netadr_t' input, but nothing ever was done with it.
* Implemented a proper initializer for the mask tables (s_nMaskTable has been removed).
* Implemented write methods in 'bf_write'. There are still some missing methods; there have to be added in later.
* Documented most functions.
* Put initializer values inside brackets.
* Put logical AND conditions within parentheses.
* Put assignments within conditional statements within parentheses.
* Mark unused variables as such to suppress compiler warnings.
* Fix vftable shadow warnings caused by ConVar::CreateInternal (does not implement, only interface. Renamed to yield desired behavior).
* Fix 'never' initialized class members for 'CCVarIteratorInternal'.
* Return values in interface vftables that cannot be pure virtual.
* Improved formatting.
* Get default logger directly instead of using a string identifier.
* Promoted size type to 'size_t'.
* Removed extraneous static variables.
The case transformation didn't work properly as the char value was not casted to an unsigned char, causing undefined behavior. Added new utility function 'IsEqualNoCase' which allows for comparing 2 strings case insensitively. Code has been tested with module strings containing irregular cases, and was still able to obtain the imported function address correctly.
* Fully commented 'UTF8Decode' to suppress warnings (currently unsupported).
* Cleaned up 'GetModuleInfo' and 'DbgPrint' to use the non-wide string versions instead.
* Added error handling in 'PrintLastError'.
* Moved 'm_pFileSystem' to 'CSourceAppSystemGroup' (actually belongs there, CAppSystemGroup has to be 0xA8 in size in order for 'm_bDedicated' to line up in 'CModAppSystemGroup').
* Prefixed all static functions with 'Static' to avoid name collisions.
Fix crash caused by vftable error. Since we are not implementing anything, but only interfacing with the game executable, we need to rename the IConVar variant's due to name ambiguity. Re-defining them in the actual class will lead into vftable misalignment and cause a crash (or other undesired behavior) as a result.
* Refactored ConCommandBase, ConCommand and ConVar class to make them all virtual, so it could interface with the game's implementation.
* Properly initialize members for ConCommand and ConVar instead of just calling memset.
* Fixed bug in ConVar registration function causing the virtual base table pointer to point to the ConCommand implementation instead of the ConVar implementation.
