Details:
* Switched SDL audio mutex to RW lock. This fixes games that continiously call SetVolume in a different thread (like Ghostbusters)

* Fixed a race condition with joins on avplayer close that caused a crash.
* kernel: Add gettimeofday
* kernel: Move sceKernelReleaseDirectMemory where it belongs
* savedata: Stub sceSaveDataDialogUpdateStatus to return finished
* memory: Add lock to VirtualQuery and remove debug print
* clang format
* fixed linux build?
* special case for sceKernelWrite (stdin,stdout,stderr)
* special case for case savedata mount
* reduced mutex spamming
* added missing default rwlock attributes init
* kernel: Add more sleep functions
* file_system: Add some functions
* memory: Missed adding some functions
* kernel: Moved some functions to time
