Reimplement panning using lookup tables, based on a patch by Christian Borss
...
This allows speaker positions to be specified by discrete angles around the
listener, providing more flexibility and configurability in placement.
Additional patches to take advantage of this are forthcoming.

Add initial AL_EXTX_buffer_sub_data support

Note that this is an in-development extension, as noted by the EXTX moniker
instead of EXT. It's behavior is subject to change, and the extension string
will be removed (replaced with the official string once it's finalized).
Developers are discouraged from using this in production code, though feel
free to play around with it.
