add support for:

 - recording, full-duplex operation
 - format conversions and resampling on the fly
 - mixing on the fly of multiple inputs of different formats
 - up to 16 channels, simplistic "routing" of channel ranges
 - more linear encodings (in raw and wav files)
the old behaviour is fully preserved if none of the new -i and -o
options are used.

code and fixes from jakemsr@ and eric@, suggestions by others.
ok "go ahead" deraadt@
