778b74cae1 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.

fc4c867f27 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.

36f133a5ae Use a modulo to keep the buffer position in range for looping sources
A high pitch and low buffer size can cause a lot of unnecessary iterations
otherwise, that just decrement the position
