20886059fd Wrap fopen calls under Windows 
The idea is that all filenames we deal with are encoded as UTF-8, but the
Windows functions that take a char string interpret it using the ANSI codepage.
So instead, we convert the UTF-8 string to a wchar string, and then use the
wchar functions for proper extended character filename support.

55f851093f Remove the now-unneeded click removal buffers for the device 
They are still there for auxiliary sends. However, they should go away soon
enough too, and then we won't have to mess around with calculating extra
"predictive" samples in the mixer.

92433532fe Don't feed the HRTF mix to the click removal and pending click buffers 
The coefficients (which control the volume and panning) already use stepping to
non-abruptly fade the mix.

81e049bd47 Step mixing gains per-sample for non-HRTF mixing 
This fades the dry mixing gains using a logarithmic curve, which should produce
a smoother transition than a linear one. It functions similarly to a linear
fade except that

step = (target - current) / numsteps;
...
gain += step;

becomes

step = powf(target / current, 1.0f / numsteps);
...
gain *= step;

where 'target' and 'current' are clamped to a lower bound that is greater than
0 (which makes no sense on a logarithmic scale).

Consequently, the non-HRTF direct mixers do not do not feed into the click
removal and pending click buffers, as this per-sample fading would do an
adequate job of stopping clicks and pops caused by extreme gain changes. These
buffers should be removed shortly.

cc599333a8 Don't try to use __restrict as a replacement for restrict 
The compiler it's intended for, MSVC, can't use it anyway because of problems
it causes with __declspec(restrict).

mixers and resamplers.
