b9e192b78a Implement a band-limited sinc resampler 
This is essentially a 12-point sinc resampler, unless it's resampling to a rate
higher than the output, at which point it will vary between 12 and 24 points
and do anti-aliasing to avoid/reduce frequencies going over nyquist.

Code provided by Christopher Fitzgerald.

dce3d0c7bf Change the Kaiser rippling limit to -60dB 
This improves the transition cutoff, shortening its width and reducing the
amount of error.

Also better handle the peaking filter gain.

63259872d1 Remove the Reverb Bost option from alsoft-config 
It's not really an appropriate setting for most users to play with. The option
still exists, but it's no longer editable in the GUI.

9ce2b8f9a7 Always update all reverb properties 
The EAX-only effect properties will be set to compatible defaults when standard
reverb is set, and the EAX-only effects will be skipped during sample
processing.

fc03a955e9 Fix the SSE4.1 resamplers 
Apparently the given _mm_extract_epi32 index obeys memory order, rather than
component order.

2a62b38530 Update filter histories even when they're not used 
If the filter properties are continually updated, and the HF or LF gain goes
from <1, to 1, and later back to <1, the history shouldn't hold stale values
from before it was at 1.

714354caee Set XYZ channel gains for source sends to 0 
It's cleaner to just set the gains to 0 rather than to special-case B-Format in
the mixer.

6689c61ff4 Remove the MIDI code 
The extension's not going anywhere, and it can't do anything fluidsynth can't.
The code maintenance and bloat is not worth keeping around, and ideally the AL
API would be able to facilitate MIDI-like behavior anyway (envelopes, start-at-
time, etc).

c4ba9d21dc Use the correct array indices for SSE register components 
SSE uses reverse ordering, such that component 0 is the last in memory.
_mm_load_* and _mm_loadu_*, and the corresponding stores, do not change the
memory ordering.
