Alex Henrie 5a81b6ac43 dsound: Dynamically allocate the global device GUID arrays. 
This removes the arbitrary limit on the number of renderers and
capturers while satisfying applications that expect the GUIDs to remain
valid after DirectSoundCaptureEnumerate returns.

*
* TODO:
* Implement SetCooperativeLevel properly (need to address focus issues)
* Implement DirectSound3DBuffers (stubs in place)
* Use hardware 3D support if available
* Add critical section locking inside Release and AddRef methods
* Handle static buffers - put those in hardware, non-static not in hardware
* Hardware DuplicateSoundBuffer
* Proper volume calculation for 3d buffers
* Remove DS_HEL_FRAGS and use mixer fragment length for it
