Pull up following revision(s) (requested by isaki in ticket #285):
        sys/dev/audiovar.h: 1.64
        sys/dev/audio.c: 1.399-1.402, 1.404-1.405
        sys/dev/audio.c: 1.406 via patch
Clean up mix_write().
--
Fix typo. sc_mrr -> sc_mpr for play buffer.
--
Remove goto in mix_write()
--
Remove meaningless sc_blkset.
audio_calc_blksize() checks whether sc_blkset is set but
it seems to be always cleared before calling audio_calc_blksize().
--
Don't assign sc->sc_pr/rr.blksize in audio_initbufs().
For hwvc, it is calculated in audiosetinfno().  And the user vc should
not change sc->sc_pr/rr.blksize.  In addition, this assignments appear twice.
--
Remove duplicated code.
For hwvc, audio_calc_blksize() appears soon again.
For user vc, the userland format and HW format are separeted, so
audio_calc_blksize() here is no longer necessary.  In addition,
vc->sc_mpr.blksize is already initialized in audio_open().
--
Separete sc->sc_pr/rr (mix ring) block size and hwvc->sc_mpr/mrr (hw ring)
block size.  Now MI audio supports(revives) device with different precision
than mix ring's precision like vs(4) (4bit ADPCM).
