1fb9311d82 Lock the device before calling aluHandleDisconnect 
PulseAudio causes an assert if being relocked inside a callback on the worker
thread, where aluHandleDisconnect is called. We can assume it's already locked
there, so just make sure the device is locked before being calling it.

92dde81296 Add rudimentary latency tracking for mmdevapi 
This won't be as granular as it could be, since it only updates when the wakeup
event trips (which may or may not happen more often than OpenAL's mix updates).
A more correct method would be to query GetCurrentPadding directly, but that
would require sending a message to the processing thread and waiting for a
reply, since we can't guarantee COM on the calling thread.

0865db564f 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.

ac4fc4026c 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.

fe6e532c87 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.
