Use EXIT_SUCCESS / EXIT_FAILURE in most cases as more granularity isn't
useful. For anim_diff, use 0 (success), 1 (image difference) and 2
(error) to align it with other diff utilities (diff, etc.).

Define macros in examples/unicode.h to use Unicode argv
on Windows. Keep char everywhere on Unix since it handles
UTF-8 without any change.
Impact:
- All fopen () and SHCreateStreamOnFile(),
- All fprintf() printing file paths,
- All strcmp() used with "-",
- File path parsing,
- Gif reading.
Concerned executables from examples/ and extras/:
anim_diff, anim_dump, vwebp, vwebp_sdl,
cwebp, dwebp, gif2webp, img2webp,
webpmux, webpinfo, webp_quality, get_disto
When compiled on Windows with Unicode enabled, webpmux and
img2webp will not work when used with an argument file and
will print "Reading arguments from a file is a feature
unavailable with Unicode binaries."

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.*

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.

After the introduction of lossy frame rectangles
we need equivalent option in anim_diff for merging similar frames.

+ jenkins fixes for native config (library order)
+ add a missing -lm
+ replace log10 by log, just in case
+ partially reverted configure.ac to remove the C++ part
