db3cb23c1d 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.

c2a6efc77a Use the panning algorithms to build the multi-channel source matrix 
This prevents the stereo-duplication option from working. It should hopefully
be restored soon.

24aaa24b5c Check for the C99 restrict keyword 
GCC does not default to C99 mode yet, so does not know restrict, however it
still allows using __restrict in its place

56d9418119 Add an HRTF filter for mono sources 
The data is based on the KEMAR HRTF data provided by MIT, which can be found at
<http://sound.media.mit.edu/resources/KEMAR.html>. The compact measurements
were used. See hrtf_tables.inc for more information.

The filter is only available for stereo output, using a 44100hz playback rate.
Note also that it currently only applies to mono sounds, and the cf_level and
head_dampen config options are ignored while it is active.
