* Fix sceNgs2SystemCreateWithAllocator
The cause of the exceptions without libraries.
* Remove error handling for unimplemented functions
Since nothing exists to create any VoiceHandle or RackHandle, we were consistently hitting those error returns.
Also promotes logs for stubbed functions back to LOG_ERROR, with the exception of two functions that get spammed pretty frequently.
* Use Core::ExecuteGuest to execute allocator alloc and free
* Clang
* Fix function definitions in ngs2.h
These should be using the SYSV ABI
* Fix function defs in ngs2_impl.h
This will (hopefully) fix compilation
* Clang
* Clang
again
* core: Split error codes into separate files
* Reduces build times and is cleaner
* core: Bring structs and enums to codebase style
* core: More style changes
