46390ba875 Additional reduction of untyped variables
These were not caught by the regex due to typos, or additional symbols that were not taken into account when making the regex.

87f9420889 Globally reduce the use of auto for function pointer declarations
Find regex pattern:
inline auto ([a-zA-Z0-9_]+) = ([a-zA-Z0-9_]+)\.RCast<([a-zA-Z0-9_:<>*]+) *\(\*\)\(([^)]*)\)>\(\);
Replace regex pattern:
inline $3(*$1)($4);

This commit also removes the unnecessary initialization (which was required to type the auto variables),
and therefore removed 6kb of unnecessary dynamic initialization code.

892fd19c4a Fix incorrect CPlayer member offset
Member offset for 'm_bGamePaused' did not align with the executable, moving the member 'm_hPlayerViewEntity' before the first bool in this row results in correct code generation (also aligns properly in the disassembly of the game's code).

32d28d4285 *::ProcessUserCmds rebuild
Rebuild of the 'CServerGameClients::ProcessUserCmds' and 'CPlayer::ProcessUserCmds' methods. The rebuild is pretty much identical to the original implementation, but with additional checks for the number of commands, and total commands in 'CServerGameClients::ProcessUserCmds'. In the future, additional clamps and checks between CPlayer and the recv'd UserCMD should be incorporated in these functions.

ef69611435 Replace memalloc calls throughout entire SDK
Global 'direct' usage of 'MemAllocSingleton()' has been jettisoned. Where possible, smart pointers were used instead. During the refactor, the following bugs were addressed and fixed:
- The virtual destructor of 'CCVarIteratorInternal' was NOT called on destruction.
- Class function 'KeyValues::MakeCopy' did NOT calculate the buffer size of the wide string correctly, the original calculation was 'len+1*sizeof(wchar_t)', but should've been '(len+1)*sizeof(wchar_t)'.

Some other code changes include:
- Tier0 include 'memstd.h' has been moved above all thirdparty includes, to make sure the memalloc functions get shadowed with ours in third party libraries as well.
- RPak file paths string literals are now defines.
- 'DestroyOverlay' has been refactored to match the assembly of the game.

ac4ab6aa1a Add reason parameter to kick/ban commands
Reason parameters are optional. For scripts, to use the default message, pass in an empty string. The function for the script system should be centralized soon to avoid more duplicate code.

3f8baf6f68 Allow setting compile options for specific targets
Previously, it was all controlled from the global init (applied to all projects), but some projects need different options. With these changes, you can disable the common options applied in the 'add_module' macro, and set your own if desired.

51ea9c7c4f CUserCmd hardening
Fix several exploitable bugs in the CUserCmd class. Some of these have been used to exploit/cheat in-game. Fixes contain:
- Camera position clamping (the only patch that hasn't been tested yet!)
- Weapon activity exploit, allowing player to infinitely throw ordnances, and perform other 'cheats'.
- Akimbo exploit + server crasher, allowing client to set multiple inventory weapons as active. The active weapon index bounds were also not checked, a properly crafter CUserCmd message would therefore be able to crash the server.

Note that this does not fix all issues related to the UserCmd class; further reversing and testing revealed there is more to be fixed, these fixes will get implemented with a future commit.

c874b7c4d8 Implement 'SVC_UserMessage' print handler properly
Check if the actual message type is 'TextMsg' before printing, since other data is binary and could be read as 'HUD_PRINTCONSOLE', 'HUD_PRINTCENTER', etc.. resulting in printing binary data. This fix permanently solves that problem. The check has also been applied to the 'ShouldReplayMessage' function.

a2468bb184 Normalize view angles in client's usercmd
Must be normalized, bad values (NAN or FLT_MAX) will crash the game. There is more that needs to be clamped, but before we can do this CUserCmd has to be reversed more.

11fd49efde Fix speed hack exploit
The frame time send from CL_Move is not sanitized on the server; clamp it to the same cvars the client is clamping them to so players busting out the clamps cannot speed hack. The values are replicated between the server and client, so if someone wants to tweak the values, it won't mess up on either the server or client.

8e379457bf Fix server code crasher in 'FireWeaponBolt'
The function 'FireWeaponBolt' calls 'CreateWeaponBolt' to create a bolt entity, but it can return NULL. 'FireWeaponBolt' does NOT check for NULL and derefs the pointer regardless. This rarely happens though; in all cases, it was caused by a defect in scripts. Code has been hooked to throw an engine error instead of crashing.

552f5f750c Fix crash in 'CClient::ActivatePlayer'
Set the persistence fields to 'ready' in 'CClient::ActivatePlayer', before executing the rest of the function. Previously, it was set in 'CVEngineServer::PersistenceAvailable', but this is too late. The function 'FairFight_Init' was actually 'CClient::ActivatePlayer', and thus it has been moved to the correct file, and the old file defining it previously has been removed.

11864f8902 Add all public headers to CMake projects
Added all public headers to CMake projects, also moved some files around in the public directory. Translation units have been moved to the libraries that were responsible for implementing them, as this game is monolithic.

9f44bcc818 Treat compiler warnings as errors
Treat them as errors globally. Most of the time a warning is a bug, or problem in code that could be solved in a different (better) manner. Thirdparty code have this disabled. The warnings as errors option can be globally disabled through the CMake GUI, but this is not recommended.

8dbc2024c6 CMake code improvements
Use the 'add_module' macro to add modules without creating duplicate code. This macro also takes a reuse PCH as parameter, so modules that need a precompiled header, could reuse those from different targets that compile them. This commit also restructures the group order of the generated solution files for easier code navigation.

f120354e96 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!
