+ split AllocateInternalBuffers() into two 32b/8b variants instead of
trying to do everything in one function.
Change-Id: I35cac9fcd990a2194c95da4b2a4046ca3a514343
Considering the fact that insert to/lookup from the color cache is always 32
bit, use DecodeImageData() variant in that case.

no precision loss observed
speed is not really faster (0.5% at max), as forward-WHT isn't called often.
also: replaced a "int << 3" (undefined by C-spec) by a "int * 8"

when establishing the need for libGL at link time.

(cherry picked from commit d640614d54)
This wasn't used often and benefits were likely minimal. Dropping it
outright is a bit simpler than adding a compatibility ifdef.
provides some compatibility with older versions of autoconf.

(cherry picked from commit ad4a367dba)
The auto-infer logic of detecting the 'Alpha' use case
(via check '(palette[i] & 0x00ff00ffu) != 0' is failing
for this corner case image with all black pixels (rgb = 0)
and different Alpha values.

(cherry picked from commit afa3450c11)
Added 1 pixel cache for palette colors for faster lookup.
This will speedup images that require ApplyPalette by 6.5% for lossless
compression.
