Fix for MSVC
...
MSVC won't accept zero-sized arrays at the end of structs, if that struct is
used in another struct that's not also at the end. This wastes a float for each
FILTER object

Make the filter history buffer size flexible
...
This lets the filter history buffer be as big as needed for a given use, so
that it can have a size large enough for the more demanding cases, but not be
wasteful for lesser-demanding cases, while not incuring the overhead of an
added pointer indirection

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.
