Fix crash caused in threading code; attempting to call a callback function. The callback ptr was assigned to uninitialized memory. Manual debugging revealed 'CEngineVGui::RenderStart' (semantic name) was causing the crash. Further research revealed that both 'CEngineVGui_RenderStart' and 'CEngineVGui::RenderEnd' weren't even necessary to draw the VGui debug overlays. These have been removed.
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.
* Use single static buffer instead of each overlay having its own (its only used in the material system thread).
* Improved readability by using ternary operators and c++ style casts.
* 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
* Added ability to invert rect to calculate offsets from bottom/right as well so debug text doesn't get out of view, or obstruct view when window is resized.
* Added Con_NPrintf() hook which shows detailed systems running times and VGUI panel debug information.
* Add Cbuf_AddText and Cbuf_Execute signatures.
* Remove additional VGui stuff from dedicated statemachine.
* Move signatures to their respective headers.
* De-inline 'CHostState::FrameUpdate()'
* Ported al new patters to GAMEDLL_S1, CEngine still recreation needs extra work
