ad6466fa6c Add 'engine_cl' project to SDK and fix compiler errors
The 'engine_cl' library defines 'CLIENT_DLL', which prunes server specific code. This is used for the 'client.dll' project. Also fixed a compile error in 'CClient::VActivatePlayer', as it used a server only cvar. Ideally, this entire file gets ifdef'd out for engine_cl, currently it doesn't matter as nothing gets compiled in.

126091d3bc Update CServer class
CClient array is part of the CPlayer class. The array has been added, filling up most of the 'unknown' gap. Vtable override functions have been added as the array is static, and therefore requires an implementation of the vtable, these are just stubs however, since the vtable pointer points to the implementation in the engine.

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.

619bbd161c Fix stringcmd replay exploit
This commit fixes an engine bug where netmessages are getting copied into the replay buffer, while these messages should never be replayed. The engine performs an internal check on 'CNetMessage::m_nGroup', and if its NOT 2, the message is getting copied into the replay buffer. All messages returning false in 'ShouldReplayMessage' are not getting copied into the replay buffer anymore. This exploit has been used in the past to route clients that were watching a replay to an arbitrary server, which essentially forms an info leak as the client attempts to connect to the arbitrary server on its own. The exploit also allows for some form of remote code execution, depending on if the client was launched in developer mode or not.

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.

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.

* Changed 'CClient' handle time to 'edict_t' which is an alias of 'uint16_t'.
* Changed 'g_pServerGameDLL' and 'g_pServerGameClients' init (obtain from factory instead).
* Use interface version macro's for obtaining factory pointers instead.
* Added 'g_pServerGameEntities'.

These get reconverted to masked byte patterns at runtime. With the signature map cache system, this will only happen when building the cache.

7804241376 CClient: add rate limit logic for 'ProcessStringCmd'
Client's can run string commands on the server with no rate limit. This means when you run 50k+ commands that are unknown, or spam 30k 'status' commands, you will be able to hang the server for 800/1200ms (15k/30kms if script printing to console is enabled!). Although the netchan processing budget system will kick you, the damage has already been done at this point. This change effectively breaks the ability to DOS the server from the client using networked string commands.
In easier words; binding 'status' to your mousewheel will get you kicked from the server, without hitching the server.

58cadb529b 'Bad behaving player' systems improvement
* Use 'CClient::Disconnect(..)' for all kicks and bans (this automatically clears the entire CClient slot, and removes the net channel).
* Only force disconnect when 'CNetChan::m_nSignonState' has a value that is not NULL.
* Clear the ServerPlayer slot on 'CClient::Disconnect(..)' and 'CClient::Connect(..)'.
* Only kick player for NetChannel overflow when value exceeds processing budget (not equals).

fdd74aa622 Implement net message processing budget
Implement net message process budget (channel gets removed if value is exceeded).
Use 'net_processLimit' to enable the implementation on the server. It will get enabled by default after testing and some cleanup. This helps against people trying to slow the server down by spamming net messages with a higher rate, e.g. using 'bind "mousewheel_up" "status"'.

5548a74d59 Major cleanup (see description)
* Fix all compiler error for GameSDK on S0 and S1.
* Remove some unused patterns and globals (launch performance gains of 100ms).
* Remove most duplicate patterns.
* Relocate globals from engine to a more appropriate location.
* Renamed some unknown vars to a more appropriate name (most of these where obtained a while back, but as we reversed more parts of the engine, some of these vars become known).
* Renamed some vars to fit the naming convention used in the SDK.
* Fixed pattern debug logging using the wrong pointer, thus displaying the wrong address.
