fb00aa5c37 Force 'CMaterialSystem::IsMaterialInternal' no inline
This seems to work a lot better for our crash handler. 'CMaterialSystem::IsMaterialInternal' still needs to be removed entirely 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.

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.

a68fda98c1 Fix crash when loading arena maps caused by recent BSP crash fix
CMaterial and CMaterialGlue derive from the same abstract classes. The function that builds the culling map uses IMaterialInternal, which is used by CMaterial, CMaterialInternal and CMaterialSubRect. Added a check for CMaterialGlue as these are valid too.

7af660d613 Fixed rare bug where models where missing during level load
Some CMaterial instances are allocated on the heap, and we only check for bounds in .data/.pdata. Checking bounds is cheap, checking valid ptr's is not. However we are lucky most of the data is within the segments, so running this isn't too costly.
This fixes the problem where the large leaf model in worlds edge was missing.

1d48574731 Refactored BuildPropStaticFrustumCullMap (see description)
Redacted most code to only perform operation to obtain studiohdr and staticprop material (read only operation, function does not modify memory used by the original 'v_BuildPropStaticFrustumCullMap()' implementation!)

The new function checks if pointer is within bounds (must stay within .data memory), if this isn't the case, the 'batch' is considered corrupt and function call to 'v_BuildPropStaticFrustumCullMap' won't proceed (note that the loop checks all bodygroups/LOD's of a model, it is possible that one doesn't have corrupt data, but a model where only one of its submeshes culls properly in the level is too much effort to fix as this function is based of disassembled output of the engine implementation, which in it self, comes with its own limitations).

For a better implementation we should proceed fully rebuilding the function (see commented function body).
The current and only problem with this is that it doesn't compute cull data properly (see bsplib.cpp line '222').

8b4df33151 Use 'sqrtf' for computing fade distance
This has to be debugged still as the computed data does not match the one computed from the engine (this is the reason the larger maps show artifacts!)

8ad4350f9f Improved BuildPropStaticFrustumCullMap
* Fixed bug where the address of g_pStaticPropMgr wasn't properly dereferenced and passed to function via its reference (engine addr).
* Fixed dword dereference.

Problems: engine still culls models improperly.

a479b4ac78 See description
Fixed rare crash in CMDLCache when buffer itteration returns invalid pointer (not null!) for handle.

Made all variables and functions used by BuildPropStaticFrustumCullMap searched dynamically (these should also work on s0, s1 and s2, they are compared but at the moment untested).

TODO: Fix deref crash properly (see bsplib.cpp l291).

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.

* Pass strings by reference for where possible.
* Split Module class to dedicated file.

d5b2e58dae Code base refactor + major performance and readability improvement. Read description for details.
* Codebase restructured to SourceSDK codebase style and .cpp/.h assertion paths in the game executable.
* Document most functions with valve style 'Purpose' blocks.
* Rename variables to match the rest of the codebase and Valve's naming convention.
* Dedicated DLL and the SDKLauncher now share the same codebase as the DevSDK.

* Obtain globals or pointers directly instead of waiting for runtime initialized data.
* Dynamically search for all functions and globals (this doesn't count for dedicated yet!).
* Initialize most in-SDK variables.

* Move certain prints and other utilities under ConVars to reduce verbosity and increase performance.
* Print all pattern scan results through a virtual function to make it easier to add and debug new patterns in the future.
* Type global var pointers appropriately if class or type is known and implemented.
* Forward declare 'CClient' class to avoid having 2 'g_pClient' copies.
* Add IDA's pseudo definitions for easier prototyping with decompiled assembly code.

* RPAK decompress Command callback implementation.
* Load decompressed RPaks from 'paks\Win32\' overriding the ones in 'paks\Win64\' (the decompress callback will automatically fix the header and write it to 'paks\Win32\').

* VPK decompress Command callback implementation.
* Move CRC32 ands Adler32 to implementation files.

* Server will print out more details about the connecting client.

* Upgrade ImGui lib to v1.86.
* Don't compile id3dx.h for dedicated.
* Don't compile id3dx.cpp for dedicated
* Implement DevMsg print function allowing to print information to the in-game VGUI/RUI console overlay, ImGui console overlay and the external windows console

* Fixed bug where the Error function would not properly terminate the process when an error is called. This caused access violations for critical/non-recoverable errors.
* Fixed bug where the game would crash if the console or server browser was enabled while the game was still starting up.
* Several bug fixes for the dedicated server (warning: dedicated is still considered work-in-progress!).
