(cherry picked from commit ee1057e3b1)
This will well isolate contributions for original code,
generated code and SIMD (especially for Android).

(cherry picked from commit 6c62841076)
brings the final libwebp.so size down 16/20K with arm64/armv7 builds
using ndk-r13

quiets a -Wimplicit-function-declaration with some configurations of gcc
(-std=c99).
_POSIX_C_SOURCE is preferred over _BSD_SOURCE with newer versions of
glibc

The image is scaled to fit the whole viewport.
Avoid some oddities with offsets, etc.
removes some TODO.

(cherry picked from commit 9310d19258)
max_i4_header_bits_ could drop to zero for difficult image and trigger
a loop. Surprisingly, StatLoop() didn't have this bug.

(cherry picked from commit 21e7537abe)
Pick the mode with the smallest alpha.
It only affects m0, in which case the mode decision is not re-examined
later in VP8Decimate(). Tests on some natural content png images show
PSNR increase as well as visual quality improvement.
Change-Id: Iea997e718cd7477160fa05eb7cfb35f4cec2fa9a
(cherry picked from commit 1377ac2ec1)
use a compile check on a separate file to avoid assuming using
arm_neon.h is safe to use without flags when just the file itself is
self-contained with GCC target pragmas.

Average3 created a slowdown of 1-2% in lossless decoding.
Average4 created a slowdown of 2-3% in lossless decoding.

...instead of the pointers stored in the array.
Should be faster (inlined) and safer.
Also: suffix explicitly the functions with _SSE2
Change-Id: Ie7de4b8876caea15067fdbe44abfedd72b299a90
Before, a first thread could enter VP8LDspInitSSE2, set
VP8LPredictorsAdd to an SSE2 version BEFORE another thread
would do the memcpy from VP8LPredictorsAdd to VP8LPredictorsAdd_C
thus leading to a C version actually being the SSE2 one (which
would then create an infinite recursion in the SSE2 predictors
at execution).

it actually disables the disposal / blending method
and just displays the raw delta values.
Useful for debugging.
