This is not an attempt to clean up the various issues with the pthread logic, instead just moving the pthread specific logic out of FEXCore in to FEXLoader. FEXCore needs to know how to create threads in an agnostic way. Which is why we obfuscate the details with this inteface. Initially this was implemented with the pthread handlers in FEXCore and expected eventually for those to get moved to the frontend. This is the time when it has been moved. This is the first step towards compiling with llvm-mingw. Still a long way to go.
