34130afe8b anim_encode: fix integer overflow 
calculate the file duration using unsigned math. this could still result
in an incorrect average duration calculation if there were multiple
rollovers. caching the duration is an option if it was desirable to
support such an extreme case.

b8821dbd81 Improve the box LZ77 speed. 
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.

c6d1db4b36 fix Android standalone toolchain build 
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.

8e42ba4c80 simplify WEBP_EXTERN macro 
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.
