stb_dxt: Remove dithering support.
...
Keep STB_DXT_DITHER so as not to break existing code that tries
to enable it, but just leave it permanently off. I originally
introduced it somewhat superstitiously because of the RGB565
endpoint resolution but it never improved either perceptual quality
or objective quality metrics, and the code is appreciably simpler
without it.

stb_dxt: Better error calc for single-color table
...
Don't truncate error as aggressively; easily done, but wanted
to keep it separate from the previous change.

stb_dxt: Initialize tables at compile time
...
Also fix a "potentially uninitialized variable" warning.
This is a modified version of Alan's original PR that keeps the
table generator in the file (in case there's interest) and also
replaces the expand[] tables with math, since it's trivial.
Fixes issue #1117 .

Remove arg from memset macro
...
My clang doesn't like the macro defined this way, choking at the callsite on line 195 with "too many arguments provided to function-like macro invocation"
This change matches what is done for STBTT_memset in stb_truetype.h

Slightly modify the public domain license to keep it in the public domain, but make it clear that even when dedications might not be recognized that the code is still usable. Given that this isn't dual-licensing under a different license, I'm hoping this will be acceptable.
