06e995f17b Server: fix incorrect calculation of player timebase on bot instances
- Member CPlayer::m_lastUCmdSimulationRemainderTime is set and checked as an int in compiled code, change type from float to int.
- Simulation time was calculated incorrectly; brough expression 'CPlayer::m_lastUCmdSimulationRemainderTime * TICK_INTERVAL' into parentheses.
- Call to CPlayer::SetTotalExtraClientCmdTimeAttempted() took incorrect parameter value if flSimulationTime < 0.0f, it was supposed to be clamped to 0.0f, but instead, took the value of 'TIME_TO_TICKS( flTimeBase )'.

42e02b4569 UserCmd: limit command backlog to prevent exploitation
Implement UserCmd command backlog limiting (the new convar 'sv_maxUserCmdProcessTicks' dictates how many ticks can be processed per second). Defaulted to 10, which is (default tick interval (0.05) * default cvar val (10) = 0.5ms window), which is equal to the default of cvar 'sv_maxunlag'.

Before this patch, you could stuff several seconds worth of usercmd's in one second and achieve speed hacking.

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.

6bc15b50b5 Put lag compensation clamping in a separate method, under a cvar that is disabled for now
There have been reports of hit registration issues, this is most likely caused by the clamping system to mitigate an exploit. Put behind a convar and disabled for now until debugged.

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.

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.

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.
