8ef242bce0 Don't use direct channels with convolution 
It may come back as an effect property, but it's probably better to not try
forcing it by default.

07989a34dc Allow higher-order B-Format buffers for convolution 
Only the first-order channels will be used, but higher-order buffers will be
allowed.

68a099ba35 Apply the first convolution segment in the time domain 
This avoids an inherent delay from the effect, at the cost of higher CPU use.
Having a customizable user-specified delay (with said user ensuring a properly
trimmed impulse response) could help alleviate the cost since once the delay
exceeds the segment size, the initial FIR filter could be skipped.

c52bf8c401 Rework effect slot buffer setting 
Rather than creating an effect-specific buffer that gets passed along as a
property, the buffer is set the effect state when the effect state is created,
the device is updated, or the buffer is changed. The buffer can only be set
while the effect slot isn't playing, so it won't be changed or updated while
the mixer is processing the effect state.

9dab2db33b Avoid copying the convolution filter history to shift it 
Instead, the current/head/newest segment is tracked, and decremented with each
process to overwrite the oldest.

801c7a9226 Initial implementation of the convolution effect 
Currently limited to mono and stereo impulse responses, and stereo IRs try to
use direct/real output rather than panning.
