ad3c4b81e2 Add experimental support for 24-bit, dual-ear HRTFs 
Currently makehrtf only handles 24-bit output, not dual-ear, and only when
given the --experimental switch. Files produced this way will not be guaranteed
future compatibility. When the mhr format is also updated with multi-distance
measurements, the experimental switch can go away.

8a735d0ba9 Add a front-stablizer config option for surround sound modes 
This improves a stereo (front-left + front-right) sound "image" by generating a
front-center channel signal. Done correctly, it helps reduce the comb effects
and phase errors associated with using only two speakers to simulate center
sounds.

Note that it shouldn't be used if the front-center channel is already included
in the positional audio mix (the dialog effect is okay). In general, it may
actually be better to exclude the front-center channel from the positional
audio mix and use this to generate front-center output.

de51ba088e Update default 5.1 and 6.1 coefficients to exclude front-center 
Not all speaker kits have a front-center speaker capable of outputing full-
range content. It's best to err on the side of caution and not include front-
center for normal positional sound by default, leaving it instead for the
dedicated dialog effect.

0a361fa9e2 "Convert" the QSA backend to the new API 
I say "convert" because it takes the lazy way and essentially just embeds the
wrappers into the backend. It's done this way because I lack the means to check
any changes, even syntactically. This also means the device's ExtraData field
is still needed.

However, this does mean all the backends are now using the new API. Code
related to the old interface can now be removed.

Chris Robinson
10ff6cba9c Make the late lines' delay the delay average for modulation 
Similar to the recent chorus and flanger changes, the modulation delay now
swings between -n to +n, where n is less than the delay length. This brings up
a slight issue with the linear interpolation, as modff doesn't produce the
correct fraction value for interpolation (it's inverted, with 0 being closer to
the next sample and 1 being closer to the base). So it's using nearest
interpolation for now.

e9505b164e Fix source sends' initial HF absorption and decay calculation 
The HF absorption is applied given the source distance, as relative to the
source's immediate environment, with additional absorption being applied given
the room/reverb environment. This does double up the amount of absorption
compared to the dry path, but it can be assumed the initial reflections travel
a longer distance.

2b14c1d623 Properly handle the chorus and flanger LFOs

a306407b67 Apply more proper air absorption to the wet path 
This properly accounts for the room rolloff factor for normal air absorption
(which makes it none by default, like distance attenuation), and uses the
reverb's decay time, decay hf ratio, decay hf limit, and room air absorption
properties to calculate an initial hf decay with the WetGainAuto flag. This
mirrors the behavior of the initial distance decay.

87d4710bc4 Apply reverb modulation to the late feedback lines 
This seems to be more in-line with the intended behavior, to allow build-up and
overlap within the reverb decay, rather than a pitch-shift on input.
Unfortunately there's no readily available implementation of this reverb model
that includes modulation to compare with, so a low depth coefficient is used to
keep it very subtle.

12fb0404c1 Reverb code update 
This update modifies the reverb in numerous ways. The 3-series, 4-parallel
all-pass is replaced with a Gerzon vector all-pass. The vector all-pass is also
applied to the early reflections, to help with the initial diffusion in the
late reverb. The late reverb filter and feedback attenuation has been replaced
with a dual first-order equalization filter, which controls the low and high
frequencies with individual low-pass/high-shelf and high-pass/low-shelf filters
with gain control.

Additionally, delay lines now have the ability to blend the output between two
offsets, to help smooth out the transition for when the delay changes (without
such, it could result in undesirable clicks and pops).

a0a41921fc Remove const from _Atomic vars to make Clang happy 
Clang does not allow using C11's atomic_load on const _Atomic variables.
Previously it just disabled use of C11 atomics if atomic_load didn't work on a
const _Atomic variable, but I think I'd prefer to have Clang use C11 atomics
for the added features (more explicit memory ordering) even if it means a few
instances of breaking const.

d9bf4f7620 Allow increasing the maximum source limit 
If the requested number of mono and stereo sources exceeds 256, the source
limit will be expanded. Any config file setting overrides this. If the device
is reset to have fewer sources than are currently allocated, excess sources
will remain and be usable as normal, but no more can be generated until enough
are delated to go back below the limit.

6cc69c8d94 Add a sample converter 
This is intended to do conversions for interleaved samples, and supports
changing from one DevFmtType to another as well as resampling. It does not
handle remixing channels.

The mixer is more optimized to use the resampling functions directly. However,
this should prove useful for recording with certain backends that won't do the
conversion themselves.

ac8b4aa5f6 Convert integer samples to float using a power-of-2 divisor 
This should cut down on unnecessary quantization noise (however minor) for 8-
and 16-bit samples. Unfortunately a power-of-2 multiple can't be used as easily
for converting float samples to integer, due to integer types having a non-
power-of-2 maximum amplitude (it'd require more per-sample clamping).
