6d4380a48c Change the backend getLatency method to return the clock time too 
This will also allow backends to better synchronize the tracked clock time with
the device output latency, without necessarily needing to lock if the backend
API can allow for it.

10dbb1bc9b Remove the Lock and Unlock methods from BackendFuncs 
All backends that still use the old interface use the default locking methods,
which is also used by the ALCbackend base.

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.

7e06a10f73 Return int and float config values through a parameter

without a separate call and check.
