2501c37044 Globally convert all byte patterns to strings
These get reconverted to masked byte patterns at runtime. With the signature map cache system, this will only happen when building the cache.

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"'.

f8f4504966 NetKey system improvements
* Installed change callback 'NET_UseRandomKeyChanged_f' for cvar 'net_useRandomKey' (when set, it will generate a random key as this is needed when this is enabled!).

e6f45aaa9b CBitBuf improvements
* Use proper types reflecting assembly from the engine in 'CBitRead::Seek' (some values are 64bit, either changed by Respawn or the compiler used by Respawn).
* Confirmed changes made to NETMSG_TYPE_BITS (now 511 instead of 255) and NETMSG_LENGTH_BITS (now 12 which is 511 max instead of 255).
* Confirmed msg HUD types.
* Enforce NET_MIN_MESSAGE on 'SVC_UserMessage::Process'.
* Remove unnecessary padding and add proper symbols where padding was actually used.

ebf4921063 Ban system improvements
NucleusID/OriginID is an unsigned type, changed all types to uint64_t and cleaned up redundant code.

efb7c36408 Light project restructure
Moved server/client headers and implementations into dedicated subfolder.
Renamed Some classes to match the game binary (e.g. CBaseClient is now CClient).
Removed redundant files.

3736d71bb1 Implement 'net_encryptionEnable' ConVar
This ConVar governs the use of encryption on game packets.
Also removed 'net_toggletrace' ConCommand and added 'net_tracePayload' ConVar as we can no longer hook on-demand as we bound the encryption parameter of the function to a ConVar.

e32cc6ae6a Code overhaul
Moved every pattern to IDetour interface. This allows for debugging patterns scans more easily, and create threads during pattern searching (Operation is now fired in APIENTRY).

Also cleaned up some unused code/extraneous comments.
Slightly increased performance by purging duplicate patterns.
Made variable search less dependent from other results (except if pattern-to-scan results is within the same header)

092b7e9d43 Start of migration to IDetour interface
Migrating to this to initialize all patterns and prototypes in Systems_Init() instead.
This should make debugging missing/not found patterns easier and allow for opting out variable/constant search (some of these require other patterns to be found, thus resulting in seg faults..).

Also added check to detect if user has a eligible CPU to run this SDK.
The game requires SSE and SSE2 instruction sets. Our SDK requires this too due to the use of SSE intrinsics, so we cannot let the game handle this. We have to check it ourselves.

8c1dfb50f4 Address class cleanup/improvements
* Move most definitions to implementation file to avoid recompiling whole program for small changes
* Pass strings by reference for where possible.
* Split Module class to dedicated file.
* Add const qualifiers to all eligible methods for address/module class
* Some renaming

e2f06a8a68 Massive performance improvements
Inline every signature defined in the SDK (previously each translation unit had its own copy of the signature and function prototype). DLL init is near instant now (85% speed improvements).

6feb41c285 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.

c187bed4c5 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
