* Add ReHLDS API files and its dependencies Note: This has been stolen from ReAPI AMXX module and modified/adjusted to match AMXX existing includes and to provide as less dependencies as possible as well * Add the necessary files to get ReHLDS interface * Split SV_DropClient into pre/post code * Init ReHLDS API and add SV_DropClient hook * Add Cvar_DirectSet hook and adjust code with helpers Note: we don't need to split code here. This is pretty much the naive and straight way, but fairly enough for our case. If it happens we got a lot more hooks, we may consider to use some class to manage better the things. * Move platform and interface stuff in their own files in public directory * Make sure to init cvar stuff after ReHLDS * Add ReGameDLL API files and its dependencies in cstrike module * Init ReHLDS in cstrike module and adjust code Note: About cs_uset_set_model(). ReHLDS API doesn't offer a way to know directly the precached models, so instead of looping through all the ressources, the models list is saved one time at map change into a hashmap. * Init ReGameDLL and adjust code * Fix linux compilation * Init ReGameDLL in fakemeta module and adjust code * Rename /reapi directory to /resdk to avoid confusion * Retrieve gamerules pointer through InstallGameRules in fakemeta module * Retrieve gamerules pointer through InstallGameRules in cstrike module Note: actually gamerules is not used if regamedll is enabled, but it could be used in future natives. * Fix a typo when ReGameDLL is not enabled * Fix missing interface check for ReHLDS. I'm pretty sure I was checking at the very first since I worked first on vanilla version of engine, looks like change has been lost.
