This may help prevent confusion when placing frame options after the
target frame.
Note for compatibility this isn't fatal, but the behavior may change in
the future.

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.*
