c13fecf908 remove the PACK() bit-packing tricks 
was too smart for its own good :)
This is more ARM-friendly, since it removes a mult.

cfb56b1707 make -pass option work with token buffers 
-pass 2 can be useful sometimes. More passes usually don't help more.
This change is a step toward being able to re-code the whole picture
with varying parameter (when token buffer is used).

733a7faae4 enc->Iterator memory cleanup 
* move yuv_in_/out_* scratch buffers to iterator

That's ~3k of stack size instead of heap.
But it allows having several iterators work in parallel.

f0d6a14b64 gif2webp: Insert independent frames at regular intervals. 
We use the 'do not blend' option for creating independent frames.
We also mark the already independent frames as 'do not blend'.

This bounds the maximum number of frames that need to be decoded to
decode a given frame, thus leading to a much better decoding performance.

df6cebfa9e 5-7% faster SSE2 versions of YUV->RGB conversion functions 
The C-version gets ~7-8% slower in order to match the SSE2
output exactly. The old (now off-by-1) code is kept under
the WEBP_YUV_USE_TABLE flag for reference.

(note that calc rounding precision is slightly better ~= +0.02dB)

on ARM-neon, we somehow recover the ~4% speed that was lost by mimicking
the initial C-version (see https://gerrit.chromium.org/gerrit/#/c/41610)

d5bad03328 Animated WebP: add "do no blend" option to spec 
Marking certain frames as "do not blend" helps avoiding alpha-blending
at decode/render time.

It also helps inserting I-frames (frames which can be independently
decoded) into the animation.
