All visuals with parameter GLX_SAMPLE_BUFFERS_ARB = 0 have
GLX_SAMPLES_ARB = 0, so the old code would only ever choose
visuals with GLX_SAMPLE_BUFFERS_ARB>=1 and GLX_SAMPLES_ARB>=1.
Some drivers do not export any multisampling capable visuals,
so dolphin fails to find a matching visual and falls back to
the single buffered visual(which does not work for some yet
unknown reason). Fixes issue #2647.

This should give the exact same shader code except for the cases of
SELA == SELB and SELC == 1, the latter only for the color combinder.
In these two cases the results of the shader should not change in any way.
It would have been possible to optimize the SELC == HALF case too, if
the actual factor had been 0.5f instead of 0.4980392f.

strcasecmp is provided by Source/Core/Common/Src/CommonFuncs.h
and vswprintf is overloaded in C++ to take the same parameters as
vsnwprintf, according to MSDN.

The real hardware probably always sends the result of its computations
to the alpha test/fog units, in parallel to its registers, but those
only take the result of the last texenv stage.
This makes grass show up in ZTP, where the last texenv stage oddly writes to
reg #3 instead of #0.

This removes some bad behaviour, like the audio thread busy waiting inside ALSA code,
missing begins of voice samples(due to DSP_HLE code not getting called often enough).
Turns out my understanding of ALSA API was lacking.
Tested with pulse plugin and directly on my intel-hda/realtek hardware.

The fix is asking alsa for a prefered "hardware" buffer size, so alsa does not fall
back to pulseaudios offering of ~1 minute. Additionally, alsa busy waits when pulseaudio
is used, sw:avail_min is set and hw:buffer_size is small.
