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.

Add a device method to retrieve the active latency
...
This is effectively the time until the next update will be heard by the user,
or the closest approximation thereof, in nanoseconds.

Use a separate backend callback to start playback of the device
...
This allows us to properly update the ALCdevice and its resources with the new
parameters before starting playback, instead of expecting the mixer to block
and wait after it has begun.
This also lets us avoid holding the device lock while resetting and starting
the device, which helps prevent lock inversion on some backends (ie, one thread
locking A then B, and another thread locking B then A), ultimately allowing
certain backends to asynchronously update the ALCdevice without risk of lockup.
Capture still has issues here, however.
