This brings minor size improvements because repetitive values in
the transform images are easily explainable through LZ77. Still,
it makes an upcoming pull request a bit more stable.
This is 971a03d820 with a fix to
not forget to analyze the end of the line.
A const has also been added to match VP8LColorSpaceTransform's
signature.

Replace the 2d histograms with uint32_t 1d versions (to avoid
pointer casting and to use the optimized VP8LAddVectorEq).

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.).

fixes warnings of the form:
/src/dsp/upsampling_sse41.c:170:1: runtime error: implicit conversion
from type 'int' of value -16 (32-bit, signed) to type 'uintptr_t' (aka
'unsigned long') changed the value to 18446744073709551600 (64-bit,
unsigned)
this is the same change as was done previously in upsampling_sse2.c:
2ee786c7 upsampling_sse2.c: clear int sanitizer warnings
Change-Id: I36064d837ad1a7a118918c16a5551fc732dec2ff
This avoids attempting to allocate 0 bytes if the call fails. (An
additional byte is added to the result to allow a '\0' to be appended.)

Options can precede the file name. This still won't be correct for
Unicode file names, but an approximation will be displayed (with '?'s)
rather than the first character if kParams.file_name were used.
glutCreateWindow() looks like it will prohibit correcting this as it
expects an ASCII string.

Use the result of find_package(SDL2); the cmake module is available
prior to downloading the port. Previously the result of this call was
ignored. This also updates the flags to use the results of
SDL2_LIBRARIES which may be more future proof than specifying them
manually.
SDL2_INCLUDE_DIRS do not appear to be necessary with -sUSE_SDL2.
Based in part on:
d0b3e8efe3/ports/libwebp/0008-sdl.patch

Change-Id: I83386b6c3d9628e3f0d9d17f20d47338d0db044a
Prebuilt SDL2 releases from https://github.com/libsdl-org/SDL/releases
provide include/SDL.h. Test for this and set WEBP_HAVE_JUST_SDL_H
accordingly.
This was inspired by:
d0b3e8efe3/ports/libwebp/0008-sdl.patch
Bug: b:301040580
Change-Id: I320ed1a23352fc4035d491399fdba184dc927554
Test: cmake .. -DCMAKE_PREFIX_PATH=<path-to-sdl2>/cmake
And include directories to imageenc/imagedec. This fixes the build with
`-DWEBP_BUILD_ANIM_UTILS=OFF -DWEBP_BUILD_CWEBP=OFF
-DWEBP_BUILD_DWEBP=OFF -DWEBP_BUILD_GIF2WEBP=OFF
-DWEBP_BUILD_IMG2WEBP=OFF -DWEBP_BUILD_LIBWEBPMUX=OFF
-DWEBP_BUILD_VWEBP=OFF -DWEBP_BUILD_WEBPINFO=OFF
-DWEBP_BUILD_WEBPMUX=OFF` and image dependencies outside of default
include locations (e.g., /usr/include).

With older toolchains, at the least, visibility attributes don't
work and all symbols are exported along with lots of unsupported
warnings.

The data mostly must persist until a call to Assemble() is made. If the
data is discarded and subsequent calls are made the behavior is
undefined.
