[silverblade] 34475: Implemented functions required to make wave playback pause and resume function (WODM_PAUSE and WODM_RESTART) using IOCTL_WAVE_SET_STATE. Modified internal I/O control routine to deal with the fact the device does overlapped I/O. Verified pause/resume functions, however there is a crash on exit if all audio buffers are exhausted by the time WODM_CLOSE is issued.

Log:
Implemented functions required to make wave playback pause and resume function
(WODM_PAUSE and WODM_RESTART) using IOCTL_WAVE_SET_STATE. Modified internal
I/O control routine to deal with the fact the device does overlapped I/O.
Verified pause/resume functions, however there is a crash on exit if all
audio buffers are exhausted by the time WODM_CLOSE is issued.
