This modifies OSS_Wave{In,Out}Init to report the exact capabilities of
the OSS driver. The new code does not try to use SNDCTL_DSP_SETFMTS
since some (old) cards may support 16bit or stereo audio at some sample
rates but not other (higher) rates. It now also reports the 48kHz and
96kHz formats if they are supported.

given the susceptibility of some OSS implementations, I'd suggest 
reimplementing the test loop as:

for fmt

	for channels

		for rates

			if open succeeds

				1/ flag format as supported

				2/ close device

			endif

		endfor

	endfor

endfor

this would also put us out of danger if the device doesn't accept 
changing its mode on the fly
