[silverblade] 34340: Some restructuring to avoid SOUND_DEVICE_INSTANCE containing members only relevant to the a wave device thread. Now there are separate structures for device, device instance, thread, and anything relevant to a wave thread. Extended overlapped I/O structure so that the completion routine can identify the device instance, completed wave buffer and thread-specific data. The completion routine re-submits the same buffer repeatedly at present.

Log:
Some restructuring to avoid SOUND_DEVICE_INSTANCE containing members only
relevant to the a wave device thread. Now there are separate structures for
device, device instance, thread, and anything relevant to a wave thread.
Extended overlapped I/O structure so that the completion routine can identify
the device instance, completed wave buffer and thread-specific data.
The completion routine re-submits the same buffer repeatedly at present.
