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.

9975aeb37f Add methods to start and stop effect slot processing 
A newly-created effect slot is in an AL_INITIAL state, in which processing is
stopped but will automatically become AL_PLAYING after successfully setting an
AL_EFFECTSLOT_EFFECT value (including AL_EFFECT_NULL or 0). Calling Play[v] or
Stop[v] will set the effect slot to AL_PLAYING or AL_STOPPED respectively.
While stopped, the effect won't produce audio and will not be processed.

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.

23259b48dd Avoid a zero-length array for the FlexArray definition 
Newer GCCs are warning about FlexArray being used at the end of another struct.
Though not the most ideal to always allocate space for at least 1 element,
actual 0-sized uses are rare and for smaller element types.
