Use do .. while (0) for macros.
--
Introduce audio_destroy_pfilters()/audio_destroy_rfilters()
and use it.
--
Remove dead codes. chan will never be NULL in SIMPLEQ_FOREACH.
--
Move defines to the appropriate place.
--
Remove mixer chan from sc_audiochan.
Now sc_audiochan contains opened audio chan (and first special
element) only.
First I splitted sc_audiochan into sc_audiochan which has
audio chan (and first special element) and sc_mixerchan
which has mixer chan only.  However nobody else refers this
sc_mixerchan except additions to list and deletions from
list.  So mixer chan's list is not necessary.
--
Split the first special element from sc_audiochan list.
- This makes sc_audiochan a list of only open audio chan.
- "SIMPLEQ_FIRST(&sc->sc_audiochan)->vc" is now "sc->hwvc".
No functional changes (except one debug message).
