This header allows us to properly switch between experimental/finished STD implementations without having to adjust the source code (required for compiling on older versions of the Visual Studio 2017 compiler).
Initial proper implementation pending cleanup.
The new system builds a manifest file when a VPK is unpacked. The manifest files contains data such as the entry flags and texture flags. It also contains a field determining whether the file should be compressed or not.
When a user repacks a pack, the system attempts to load this manifest file and does a lookup to the object to retrieve the flags (most of these flags are unknown, but they are used by the engine and are necessary for stuff like cubemaps and texture files to work correctly. Cubemaps won't work with proper flags, and textures (decals, particle system components, etc..) will look washed out without them.
I think some also determine whether a file within the VPK should be cached or not, so simply marking everything as 0x101 will probably end up in more CPU time and higher filesystem cache usage (depot/ is only 0x1, I don't think anything there is getting cached ever without the 0x100 flag).
User could also repack a VPK while excluding anything that is not in the manifest file. So you could unpack all VPK's into a single directory (each VPK has its own manifest file tied to its level name), and rebuild all the VPK's with only the files that where originally in them.
fs_pack_vpk command usage: <locale> <context> <level_name> <manifest_only>
locale determines the pak language (default english), context determines whether is a server/client vpk, level_name determines the BSP name of the pak, manifest_only determines whether the pack system should only include files within the manifest (leaving this arg out will build all files into the vpk).
The VPK workspace path is determined with ConVar 'fs_packedstore_workspace'.
* Dedicated SDK now supports ASLR enabled executables.
* Complete removal of CEngineClient on the dedicated server.
* Complete removal of gHLClient and g_pHLClient on the dedicated server.
* Performance improvements for the dedicated server frame loop.
* ConVar 'CVCallback_t' structure rebuild.
* Reduced overhead throughout SDK.
* 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
