Partial CNetChan class rebuild and implementation (see description) * Adapt codebase to new class to reduce rune-like code. * Fixed several bugs where the global CClient pointer was used instead of the instance in question to issue bans and display information about a certain client in CBanSystem and Pylon. * Upgraded CBanSystem and Pylon to use IPv6 instead (including IPv4 mapped IPv6 addresses). This breaks all existing banlist files! All bans have to be re-issued or the existing file has to be updated to use IPv4 mapped IPv6 addresses and renamed to 'banlist.json', and moved to the root of the 'platform' folder.

#include "mathlib/color.h"
Initial port to CMake * All libraries have been isolated from each other, and build into separate artifacts. * Project has been restructured to support isolating libraries. * CCrashHandler now calls a callback on crash (setup from core/dllmain.cpp, this can be setup in any way for any project. This callback is getting called when the apllication crashes. Useful for flushing buffers before closing handles to logging files for example). * Tier0 'CoreMsgV' function now calls a callback sink, which could be set by the user (currently setup to the SDK's internal logger in core/dllmain.cpp). TODO: * Add a batch file to autogenerate all projects. * Add support for dedicated server. * Add support for client dll. Bugs: * Game crashes on the title screen after the UI script compiler has finished (root cause unknown). * Curl error messages are getting logged twice for the dedicated server due to the removal of all "DEDICATED" preprocessor directives to support isolating projects. This has to be fixed properly!

Tier1: properly implement ConVar change callbacks Change callbacks actually take a structure of 2 pointers, one being for the callback itself, and the other being 'userdata' which typically is used to sync the ConVar with VGUI slider elements. This issue was noticed after implementing the ADS scalars and attempting to hook them up to VGUI, only to find out it would crash due to this lacking detail. All change callback prototypes had to be adjusted.

Tier1: static construction of ConVar objects during link time Fully implemented ConVar class so we could statically construct all SDK convars, this avoids a level of indirection, and allows for creating ConVar's everywhere in the project. This patch also removed the settings tab of the ImGui server browser, as it has threading issues, while it technically never caused a crash yet, it has been removed as there was no point keeping it vs the work required to make it thread save (it only managed 2 convars which are perfectly manageable through cfg's or the in-game console).

Tier1: static construction of ConVar objects during link time Fully implemented ConVar class so we could statically construct all SDK convars, this avoids a level of indirection, and allows for creating ConVar's everywhere in the project. This patch also removed the settings tab of the ImGui server browser, as it has threading issues, while it technically never caused a crash yet, it has been removed as there was no point keeping it vs the work required to make it thread save (it only managed 2 convars which are perfectly manageable through cfg's or the in-game console). Also temporarily disabled the creation of ConVar's in the mod system due to a memory leak, we would allocate and register a convar based on details parsed out of a mod file definition, but never unregister and free it.

Potential fix for intermittent crash during playlists reload This should fix a rare crash that happens when the playlists file is reloaded during disconnect. The client fetches the playlists from the server on connect. On disconnect, we want to reload the one from the client so that if the player want's to create his own game, that he would have his own playlists. The fix is to delay the reload of the playlists file to the beginning of the next frame.

Partial CNetChan class rebuild and implementation (see description) * Adapt codebase to new class to reduce rune-like code. * Fixed several bugs where the global CClient pointer was used instead of the instance in question to issue bans and display information about a certain client in CBanSystem and Pylon. * Upgraded CBanSystem and Pylon to use IPv6 instead (including IPv4 mapped IPv6 addresses). This breaks all existing banlist files! All bans have to be re-issued or the existing file has to be updated to use IPv4 mapped IPv6 addresses and renamed to 'banlist.json', and moved to the root of the 'platform' folder.

RCON implementation (see description) * 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

IDetour: code refactor Utilize the new IDetour::DetourSetup() code, IDetour::Attach and IDetour::Detach have been removed in favor of this (significantly reduces chance of user error). Since the template check happens in the idetour header, it is much more aggressive on type mismatches, such as a difference in parameter types, between the function and detour, will now raise a compile time error. As a result, some type mismatches have been fixed in this commit as well.
