When fatal is set, the function will show a error dialogue, which will halt the process and close when the message is dismissed. Else we will end up in a crash.
* Implemented robust length-prefix framing logic for non-blocking sockets (previously used character sequences to determine length, but you cannot use character sequences on protocol buffers as its binary data. This logic should fix all problems regarding some commands not getting networked properly to the server and stuff not getting printed on the client).
* Increased buffer size to std::vector::max_size when netconsole is authenticated (MAX_NETCONSOLE_INPUT_LEN still remains enforced on accepted but not authenticated connections to prevent attackers from crashing the server).
* Process max 1024 bytes each recv buffer iteration.
* Additional optimizations and cleanup.
* 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).
** SERVER **
* Close redundant connections if max sockets have been reached.
* Ban if client keeps spamming without authing first (ignoring message).
* Check for whitelisted address before issuing bans (whitelisted address in ConVar 'sv_rcon_whitelist_address' will never get banned or get its connection terminated.
* Transmit SQVM and DevMsg logs over the wire to the net console.
** NETCON **
* IPv6 support.
* Close connection properly after FIN request.
* Prompt user to reconnect after connection has been terminated instead of closing the application.
* Add proper quit command.
** SDKLAUNCHER **
* Rename to 'launcher.exe' to describe its purpose better. Our logo gets printed nice and large on the console during startup.
** SDK **
* Cleanup.
* Fully rewritten protocol agnostic CNetAdr class
* Fully rebuilded legacy CNetAdr class
* Fully rebuilded dual-stack CSocketCreator class
* New project "netconsole" added (lightweight netconsole for RCON)
RCON is still work in progress
