rcombs ba81e4ed88 ao_audiounit: get the channel layout from the AU itself
Fixes 5.1/7.1 output mapping on tvOS 16,
and also makes the AC3-layout hack unnecessary.

Also adds some diagnostic log messages.

wm4 6b13d71cdc audio: remove unused ring.h includes
From what I can tell, this has been copy-pasted from times when
ao_coreaudio still used its own ringbuffer, instead of the common code.

wm4 d27ad96542 audio: redo internal AO API
This affects "pull" AOs only: ao_alsa, ao_pulse, ao_openal, ao_pcm,
ao_lavc. There are changes to the other AOs too, but that's only about
renaming ao_driver.resume to ao_driver.start.

ao_openal is broken because I didn't manage to fix it, so it exits with
an error message. If you want it, why don't _you_ put effort into it? I
see no reason to waste my own precious lifetime over this (I realize the
irony).

ao_alsa loses the poll() mechanism, but it was mostly broken and didn't
really do what it was supposed to. There doesn't seem to be anything in
the ALSA API to watch the playback status without polling (unless you
want to use raw UNIX signals).

No idea if ao_pulse is correct, or whether it's subtly broken now. There
is no documentation, so I can't tell what is correct, without reverse
engineering the whole project. I recommend using ALSA.

This was supposed to be just a simple fix, but somehow it expanded scope
like a train wreck. Very high chance of regressions, but probably only
for the AOs listed above. The rest you can figure out from reading the
diff.

Aman Gupta e35aca3cb4 ao/audiounit: improve a/v sync
This more closely mimics ao_coreaudio, on which this driver was
originally based.

Josh Lehman 515c4163ea ao_audiounit: rename pause function to reset
AudioUnit output driver uses the pull based api so it should have
a reset function instead of a pause function.

wm4 c87224bf1b ao_coreaudio: change license to LGPL
All authors have agreed to the relicensing.

The code was pretty much rewritten by Stefano Pigozzi. Since the rewrite
happened incrementally, and seems to include refactored portions of
older code, this relicensing was done on the pre-refactor code do.

The original commit adding this AO (as ao_macosx.c) credits Timothy J.
Wood as original author. He was asked and agreed to LGPL. It's not
entirely sure from which project this code came from, but it's probably
libao. In that project, Stanley Seibert made some changes to it (who as
a major developer of libao was asked just to be sure), and also Ralph
Giles and Ben Hines made two small changes. The latter were not asked,
but none of their code survived anyway.

wm4 1a2319f3e4 options: remove deprecated sub-option handling for --vo and --ao
Long planned. Leads to some sanity.

There still are some rather gross things. Especially g_groups is ugly,
and a hack that can hopefully be removed. (There is a plan for it, but
whether it's implemented depends on how much energy is left.)
