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.

e4d5b2502d fix a bug where opening for write would not fail if channel allocation failed

channel dead - fail all future operations

do various mmap-related ioctls right.

improve blocksize control.

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.
