Move the device lock into the backend function table
...
For backend-specific implementations: this should hold the audio mixer loop for
playback devices, and provide recursive mutex behavior.

Keep the backend device open until the last reference is released
...
This should generally happen with the next ALCdevice_DecRef call unless the
device is in the middle of being used in another thread, in which case it's
probably best to not remove the resources.

Don't unlock the pulseaudio mainloop when mixing
...
Lock contention could cause a lengthy delay between mixing and writing the
audio. There shouldn't be any risk of dead-locking as the device lock should
never be held when the mainloop gets locked.

These functions should not fail, but there seem to be bugs that cause them to

though, so anything is better than nothing here.
