eefda551de Properly handle input samples for changes with the FIR coefficients 
This makes sure previously processed samples are not changed due to changes in
the FIR filter. It also applies the coefficients in ascending order with the
values, to improve caching.

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.

eb489ac886 Store double formats as float 
The mixer will cut it down to float anyway, so it's unnecessary and needlessly
creates more mixer functions
