Allow effect slots to be updated asynchronously
...
Updates when the slot changes effect type is still sychronous, however, to
ensure a proper state for the Process method call. Fixing this would
essentially require all effects to work from the same state.

Add a source property to skip channel virtualization for multi-channel buffers
...
With virtualization disabled, channels are mapped directly from input to output
and any input channel that is missing an output is dropped. Any virtualization
effects (such as HRTF filters) for positional cues are also skipped.
The idea is to allow applications a way to play pre-filtered audio that channel
vitualization effects could interfere with.

Add an option to reverse Z panning of mono sources
...
Applications that are not built around OpenAL's orientation system need to
convert their given vectors to it. Depending on how this is done, it can lead
to proper stereo (left-right) panning with improper surround sound (front-back)
panning, which thusly sounds correct with stereo output and incorrect with 4+
channel output.
This option is intended to help fix playback of such applications on surround
sound systems, without having to resort to forcing stereo output.
