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.

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.

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.

7912b79fa2 CL_CopyExistingEntity: implement missing bounds check
Implement bounds check for non-sanitized value of u.m_nNewEntity.
Debug builds of the engine have an assertion, however in release these are stripped.
This fixes a full chain client RCE exploit, for more information, see: https://ctf.re/source-engine/exploitation/2021/05/01/source-engine-2/
