7e81918f7b Update HRTF code 
This update allows for much more flexibility in the HRTF data. It also allows
for HRTF table file names to include "%r" to represent the device's playback
rate (e.g. if you set hrtf-%r.mhr, then it will try to use hrtf-44100.mhr or
hrtf-48000.mhr depending if the device's output rate is 44100 or 48000,
respectively).

The makehrtf utility has also been updated to support more options and input
file formats, as well as the new mhr format.

23bfb03d2a Improve the external HRTF data file format 
Although more parameters are read from the file, some must currently conform to
specific values. In the future, these restrictions may be lifted.
