Add missing types to fully mapped out PakGlobals_s struct, which is a 13MiB+ structure! This covers the vast majority of the pakfile system which is why we had to change a bunch of stuff for this patch. This patch also comes with:
- Reversed 'JobFifoLock_s' structure
- Reversed 'PakTracker_s' structure
- Reversed 'PakAssetTracker_s' structure
Many globals have been dropped as they were covered by the large PakGlobals_s singleton.
The pak decoder logic has been changed up as well, we now use a decode mode enumerant which will make it easier to add in more decoders for the pak files in the future.
Pak files above 4GB caused the async file system to throw an error about failing to load audio banks, removed casts and promoted everything correctly. Also removed irrelevant comments in the public pakfile header.
* split rtech_game and rtech_utils cpp files into multiple files
* rebuilt several large pak load routines for debugging and custom implementations
* moved rson code to rtech_game
* reworked and improved engine and sdk pak precache system
* reversed more of the jobthreads system
