Log Message:
libossaudio: Various OSSv4 fixes to allow reference programs to compile

- Define various new AFMT_*. These are not returned as supported
  formats by SNDCTL_DSP_GETFMTS, because it would be very silly to
  have Vorbis in the kernel.

- Implement PLAYTGT and RECSRC. For each NetBSD audio device
  we only return one playback and recording source, "primary".

- Return preferred channel configuration in capabilities.
  Either DSP_CH_STEREO, DSP_CH_MONO, or DSP_CH_MULTI
  depending on the current hardware format.

- SNDCTL_DSP_HALT_* simply flushes the audio device.
