cwebp, gif2webp, img2webp, vwebp and webpinfo are modified in this
change to align with the other examples. When given no arguments, the
examples print their help output and exit with failure.

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.).

this makes the output from img2webp and the ordering in doc/tools.md and
man/img2webp.1 consistent

Both are global settings. Modifying them at the frame level is left as a
follow up based on need.

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."

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