* 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, and setting volume in HEL primary buffer
|
|
* Optimize WINMM and negotiate fragment size, decrease DS_HEL_MARGIN
