CommandLineToArgvW() returns a LPWSTR*, storing to const LPWSTR* is
incorrect without a cast; fixes gcc -Wincompatible-pointer-types
and clang(-cl) -Wincompatible-pointer-types-discads-qualifiers warnings

It's safer to clip the passed param instead of doing 32b arithmetic
and clipping afterward.
Output is unchanged, but code no longer rely on UB.

dst->cur_ was not set.
The bug occurred only with several VP8LBitWriter instances
(thread_level > 0) and in 32-bit (in 64-bit, src->cur_ was
always 0 in VP8LBitWriterClone()).

Move IsFlat to its own header. This allows it to continue to be
inlined. Using the RTCD and creating a distinct function slows down arm
builds.

thresh is defined by FLATNESS_LIMIT_* which ranges from 2-10.
score_t is int64 which is a touch overkill.

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%.

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.

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.

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."
