coreaudio: Use the standard SDL audio thread instead of spinning a new one.
Fixes corner cases, like the audio callback not firing if the device is
disconnected, etc.

coreaudio: changed device close procedure to prevent long hangs in some cases.
The audioqueue thread needs to keep running, and processing the CFRunLoop
until the AudioQueue is disposed of, otherwise CoreAudio will hang waiting for
final data to feed the device.
At least, I think this is how it all works. It definitely fixes the bug here!
Since AudioQueueDispose() calls AudioQueueStop() internally, there's no need
for our thread to handle this, either, which is good because the AudioQueue
would be disposed by this point. So now the AudioQueue is disposed first, and
then our thread is joined, and everything works out okay.
Just in case, we mark the device "paused" before setting everything in motion,
so any further callbacks from CoreAudio will write silence and not fire the
app's audio callback again.
Fixes Bugzilla #3868.

coreaudio: we don't need to track number of allocated audio buffers anymore.
CoreAudio takes care of iterating through the buffers and freeing them now,
so we don't have to manage this ourselves.

coreaudio: Better handling of audio buffer queue management.
We don't fill buffers just to throw them away during shutdown now, we let the
AudioQueue free its own buffers during disposal (which fixes possible warnings
getting printed to stderr by CoreAudio), and we stop the queue after running
any queued audio during shutdown, which prevents dropping the end of the
audio playback if you opened the device with an enormous sample buffer.
Fixes Bugzilla #3555.

coreaudio: dynamically allocate AudioQueueBuffers.
We need more than two buffers to flip between if they are small, or CoreAudio
won't make any sound; apparently it needs X milliseconds of audio queued when
it needs to play more or it drops any queued buffers. We are currently
guessing 50 milliseconds as a minimum, but there's probably a more proper
way to get the minimum time period from the system.
Fixes Bugzilla #3656.

audio: fixed more "spec" references that should have been "callbackspec".
This should catch all the ones for audio targets that have provided their
own audio threads.

Note that linking with AVFoundation is now required if you don't disable SDL_audio compilation on iOS and tvOS.
