513693be6c rework feeder sytem to allow feeders in klds 
modify driver capability reporting format to list every audio format
seperately- required for above and because we could not previously indicate
that mono was unsupported.

there should be no functional impact.

98d83734f4 this is a full fix for writes not aligned to the sample size selected. 
should be a no-op in most cases.

5b78a73443 * add a non-reset device- will not reset the channel on open. you 
will have to mknod yourself for now.
* don't eat the first write()
* partial rvplayer fix- don't panic on unaligned writes unless our
  feeder chain requires them for downconversion.  a fuller fix is
  on the way.
