Rebuilds SV_BroadcastVoiceData with an additional check of "sv_alltalk" cvar to disable team checking, allowing for servers to enable global voice chat
If 'sv_rcon_maxconnections' is set higher than current auth socket count, reopen listen socket. If its set lower, close all sockets until auth socket count matches 'sv_rcon_maxconnections'. Sockets are getting closed in reverse order, so the netcon that connected last will be disconnected first.
* 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).
* Prevent attacker from being able to abuse and overflow the banned list vector.
* Improved IPv6 comparison performance.
* Change size fields of payload frame from unsigned to signed.
* Close all accepted sockets on RCON server shutdown.
* 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.
Fixed bug caused by incorrect type conversion. Type should be as wide as the type used for 'CUtlMemory::m_nAllocationCount', which is 64-bits on this particular implementation.
Recently, there has been a sudden influx of players playing with a name that isn't valid. Names such as " " or "@something $very !crazy". This patch fixes this problem by enforcing checks during connect by default.
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.
