[silverblade] 34316: Implemented routines for querying if a particular wave format is supported by an audio device. This is done by sending IOCTL_WAVE_QUERY_FORMAT to the driver. This has been tested with the NT4 Sound Blaster driver, which return success for 22050Hz/16bit/Mono, and returns MMSYSERR_NOTSUPPORTED if the same request is then sent with a request for an abnormally high number of channels.

Log:
Implemented routines for querying if a particular wave format is supported by
an audio device. This is done by sending IOCTL_WAVE_QUERY_FORMAT to the driver.
This has been tested with the NT4 Sound Blaster driver, which return success
for 22050Hz/16bit/Mono, and returns MMSYSERR_NOTSUPPORTED if the same request
is then sent with a request for an abnormally high number of channels.
