use a fixed frequency (48kHz) and configure the audio server at attach time, instead of at the beginning of playback
improved playback error handling, and get rid of junk+silence insertion at the beginning of playback
expose vchi_get_peer_version
capture peer version; if less than 2, bail out as bulk mode is not supported. report the peer version with "audioctl version"
Some improvements that make playback mostly reliable for me - the final
piece of the jigaw is probably in vchiq:
- prefill vchiq with a number (currently 2) blocks of audio before
   starting
- use a kthread as workqueue isn't suited to our usage.
- don't drain on stopping as for some reason it leaves data behind.
