  WinRT: made SDL_xaudio2.c compile as C code when building for WinRT XAudio2 2.8's header file, xaudio2.h, doesn't compile in plain C code for WinRT apps, not automatically at least. Initially, this file was adapted to compile as C++, however these changes are now deprecated in favor of some preprocessor based hacks that should get xaudio2.h to compile (while making sure XAudio2 still works).
