9f10ae466c Convert the OpenSL backend to the new backend API 
This also removes the buffer queue callback's call to aluMixData, which could
potentially block on a mutex.

b5b3ea95f8 Add a config to output first-, second-, or third-order ambisonics 
Currently incomplete, as second- and third-order output will not correctly
handle B-Format input buffers. A standalone up-sampler will be needed, similar
to the high-quality decoder.

Also, output is ACN ordering with SN3D normalization. A config option will
eventually be provided to change this if desired.

0051a96376 Fix 5.1 surround sound 
Apparently, 5.1 surround sound is supposed to use the "side" channels, not the
back channels, and we've been wrong this whole time. That means the "5.1 Side"
is actually the correct 5.1 setup, and using the back channels is anomalous.

Additionally, this means the 5.1 buffer format should also use the the side
channels instead of the back channels.

A final note: the 5.1 mixing coefficients are changed so both use the original
5.1 surround sound set (with the surround channels at +/-110 degrees). So the
only difference now between 5.1 "side" and 5.1 "back" is the channel labels.

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.
