GIFDisplayError() is already defined exactly the same way
in gifdec. Remove it from anim_util.c and add dependency.

with loop_compatibility disabled (the default), non-zero loop counts
will be incremented by 1 for browser rendering compatibility. the max,
65535, is a special case as the muxer will fail if it is exceeded; avoid
increasing the limit in this case. this isn't 100% correct, but should
be close enough given the high number of iterations.

This is to harmonize the -h/-version options on all our examples.
+ added GetAnimatedImageVersions() method to anim_util.*

this is consistent with web browser behavior as well as various
transcoding tools (ffmpeg, gif2apng, etc).
also: update anim_diff to account for this new behaviour.

the sizes are already validated by CheckSizeForOverflow(), add casts to
size_t to avoid -Wshorten-64-to-32

some multiplies here and there needed some extra checks
and error reporting. Even if width * height is guaranteed
to be < 2**32, we were multiplying by num_channels and
triggering a 32b overflow.
Some multiplies were not using size_t or uint64_t, additionally.

Change it from transparent white to transparent black, which matches
the transparent color assumed in Webp dispose-to-background method.
Also pre-multiply background colors before comparison in anim_diff,
just as what is done with regular pixel values.

+ jenkins fixes for native config (library order)
