Some more work on the 'sound' bochsrc option
 - added 'wavein' parameter to specify the wave input device if necessary
 - if 'wavein' is not set, Bochs uses the 'waveout' value for input, too
 - SB16: the 'wave' parameter is now only used to specify the filename (mode 2 or 3)
 - TODO: implement 'wavemode' feature for ES1370 similar to SB16
