as written in my previous mail, it was a quick hack.  and there is a
better approach.

the attached patch will add a new plugin, asym, which defines
different slave pcms for playback and capture streams.
for example,

	pcm.duplex {
		type asym
		playback.pcm "dmix"
		capture.pcm "dsnoop"
	}

then you can use the pcm "duplex" for dmix/dsnoop combination.

	% aplay -D duplex foo.wav
	% arecord -D duplex bar.wav

(in reality, you likely need plug layer in addition to support other
 sample rates, though.)

also, by defining

	pcm.dsp0 "duplex"

you can use it via aoss, too.


i'm not sure whether the name "asym" is the best choice.
if you have better idea, please let me know before committing to cvs.
