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.

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.

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.

The graphical bug happens when there is a frame disposed to background
color, followed by another frame that does not blend, and their areas
don't fully overlap. Only the previous frame clears its part of the
viewport. The fix consists in clearing the screen for the previous and
the current frame if needed.

Option -usebgcolor may be used to display ANIM background color (or white if no ANIM chunk), blended on top of checkerboard. By default this is disabled (old behavior) to easily see transparent areas. Spec says that "background color MAY be used", so it's an option.
Key b may be pressed to toggle ANIM background color display. There are visual artifacts (leftovers) when toggling during an animation. This is already the case for rescaling, toggling info etc. (fixing it implies storing viewport render or rendering whole animation from start till current frame).

Container spec indicates that background color is written
in BGRA byte order, but glClearColor() parameters are RGBA.
Anyway the checkerboard is displayed right after glClear()
calls so it replaces background color.

We should be using 'floor' when doing the final divide.

I'll update and re-enable it in a later
patch, since this code needs some refactoring first.
