improved audio resampling for limited featured sound cards (like the ones found in
laptops, supporting only 16 bits, only stereo etc). as added bonus of new "stackable"
conversion scheme fixes resampling for 8 bit streams.
(thanks Damien Clermonté for discussion and ideas)
note1: alsa patch untested.
note2: pass-through untested.
