179e1c4dbc Don't check for space in the ringbuffer before trying to write 
The write method already checks and returns how much it managed to fit in.

03274a5b95 Ensure at least the specified ringbuffer size is writable 
Previously, all but one of the specified size could be written (so for a size
of n, only n-1 was guaranteed writable). All users pretty much compensated for
this, but it makes more sense to fix it at the source.

59768674f1 Use an alternate ambisonic HRTF decode layout 
Similar to the previous, but includes the top and bottom HRTF responses. The
higher-order decode (for the "basic" HRTF output) also now uses 2H1P mixed-
order instead of 2H1V, which seems more stable.

1e93122470 Remove unused reverb modulation code 
Still unsure how to handle reverb modulation without some kind of reference
output, so remove the related functions to not waste CPU time. It'll remain in
the Git history should it ever need to be resurrected.
