Direct copy of sse2. Slight improvement because neon has
abs().
flower.ppm had minimal improvement. Somewhat expected because
GetResidualCost_C is only ~3.6%
mug.ppm had a better improvement because GetResidualCost_C is
almost 9%.
C 2.150
NEON 2.130

Much faster with aarch64. Still somewhat faster without vmaxv.

The old code simply did not make sense.
The effect is that the pair would be popped from the
queue no matter what; as the queue is small, it does
not matter that much on the results.
But it will matter for a later CL.

(cherry picked from commit 485ff86fbb)
Stick to the strict necessary for running webp_js,
and avoid building sub-lib or examples with heavy dependencies.

Also, histograms in a HistogramSet can be initialized all
at once.

(cherry picked from commit 6752904b2f)
When histograms are empty, it is easy to add them.
They should also not be considered when merging histograms
(it is a waste of CPU).
This does not change the compression performance,
just the speed.

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."

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

A complete row of # is replaced by only one,
so add a space after the first one to keep it.

To be compiled with Visual Studio on Windows through CMake.
Targets are get_disto, vwebp_sdl, webp_quality.

Instead of unsetting WEBP_BUILD_GIF2WEBP,
disable it to keep it displayed in ccmake.
Disable WEBP_BUILD_GIF2WEBP before it's tested.
Do the same for WEBP_BUILD_ANIM_UTILS.
