WEBP_MAX_IMAGE_SIZE can be defined to control this limit.
Set it to 1.5GiB w/--config=asan-fuzzer to avoid OOM with large resolution
images. This limit leaves some headroom over the single image max of 2^14 *
2^14 * 4

For a pixel, we look for the longest match starting in a window around it.
For the following pixel, the previous result can be used and smaller
search window is used.

add a check for cpu-features.h and rework some of the ifdef's around
android + neon. for android builds with cpu-features enabled the
*_neon.c files will still need to be flagged correctly (with e.g.,
.c.neon in Android.mk) to properly build them.

including the type in the macro doesn't bring much benefit to ordering,
current platforms work with a prefix, this would be insufficient if the
attribute needed to follow the function prototype. this form makes it
easier to override on the command line.

we use a static guard to only call SDL_Init() once.
Another option would be to call SDL_Quit(), but it doesn't seem to be
doing anything.
Also, fix the HTML code and add 'use strict' directive.

- some image libraries define _INCLUDE_DIR and not INCLUDE_DIRS.
- CMakePushCheckState is a non-destructive way of changing the
CMAKE_REQUIRED_* variables.

GIF find_package only locates the header and library, it doesn't fail
compile tests when detecting the version, but falls back to 3 (as of at
least cmake 3.7.2). Make sure the library links to avoid incorrect
detection when cross compiling.

If "exact" is false, we can modify the luma samples in fully transparent
areas to facilitate lossy compression. Experiments on some PNG images
show compression improvement of more than 20%.

this avoids the result being cached in a common variable causing
potentially incorrect results in future tests and improves the logging

Half of the functionality was duplicated.
The rest is about the alpha channel handling so we
might as well put it in the appropriate file.
