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.

2d4453968d Implement AL_SOFT_buffer_sub_data using the current AL_EXT_buffer_sub_data spec 
This extension can be useful for some applications, but a full EXT version may
not be ready for some time. Using the SOFT moniker will help differentiate it
in case changes need to be done for the EXT version.
