- Start rewrite of DirectSound

- Start rewrite of DirectSound
- Implemented DirectSoundEnumerateA, DirectSoundEnumerateW, DirectSoundCaptureEnumerateA, DirectSoundCaptureEnumerateW, GetDeviceID
- Partly implemented IDirectSound8 / IDirectSoundCapture8, IDirectSoundCaptureBuffer, primary / secondary IDirectSoundBuffer8 interfaces
- DllRegisterServer / DllUnregisterServer are taken from Wine DSound implementation (John K. Hohm)
- Currently only one primary + secondary buffer are supported for playback
- Mixing of IDirectSoundBuffer is not implemented
- Capture mode isnt yet supported
- Vlc now can use dsound for playback, though stutters in low quality streams are present
- Dsound is not yet added to build untill it has stabilized more
