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.

f1ce139997 Use SSE to do 4 samples at once (non-HRTF direct mix), instead of to apply a matrix row 
MaxCHannels no longer needs to be a multiple of 4 now, either.

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.

611bd0b2d3 Add a method to calculate gains given a sound point and its half-width, and use it for reverb 
The half-width ranges from 0 to pi, and essentially specifies the coverage area
around the listener. At 0, it's an infinitely small point sound and behaves
like a usual panning sound. At pi/2 it covers half the area, and at pi it
covers the whole area.

fcf9034c2b Calculate the listener matrix when a new orientation is specified 
This is so the matrix isn't derived each time a source is updated, and it will
make supporting user-defined matrices easier.
