99cabd2ac8 UserCmd: cleanup variable names and comments
Reversed some extra field names + adjusted comment for clamping ucmd->camerapos (this was tested and works, this field should be clamped).

609d705a0c 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.

edc52ad669 IDetour: remove extraneous pointer assignments
Originally, we store the search results in a CMemory instance which we then assign to the actual function pointer. CMemory is just a pointer class; we can assign the results directly to the actual function pointer. This commit reduces a lot of code verbosity, and also reduced roughly 2KiB worth of static pointers in the resulting executable. This commit also officially deprecates the support for any GameDLL's below S3 (Season 3), since it makes more sense to port the assets from earlier/later games back to the version this SDK supports.

144d5f62e1 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.

75e327e447 Normalize pitch angles
Prob not needed, but other unclamped angles/vectors were able to crash games in the past, so just normalize this too.

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.

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.

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.

359820615f Move low level code to tier0/tier1
Moved to tier0/tier1 so it could be compiled into a static library in the future.

a618990937 Detour code refactor
This change was planned for a long time. This moves all REGISTER calls to a single translation unit, this is required as we currently added a very dirty workaround for not registering duplicates by checking if VFTable pointer was already present in the vector... Registering from single translation unit prevents duplicate instances that gets created if header is included by more cpp files.
Reworking this reduced 100kb+ of compiled code. This commit also reworked the way functions/variables/constant gets logged with their addresses; the new code formats them on the fly, and allows for resize at any time. Formatting is no longer required by programmer.

TODO: currently there are some compile errors for dedicated and client dll's. These will be resolved very soon as they need to be properly worked out still (server & client only stuff needs to be properly split). Use the 'main' (stable) branch for the time being if you need to compile these dll's.

4710b51fa3 Experimental bot simulation implementation
Simulate bot user commands on the server. The simulation system is experimental and only runs if cvar 'sv_simulateBots' is set, and bots are created on the server.

afe8efbc2a Add CUserCmd class to SDK
Implemented CUserCmd to SDK. Constructor resets the class using the game's 'Reset' implementation as the majority of the structure is unknown.
