b4e731cd93 neon-implementation for rescaler code 
It's better to stay with a 32b fixed-point precision overall, otherwise
the C-version on ARM gets *slower*.
Actually, gcc ARM compiler optimizes some instructions pretty
well when WEBP_RESCALER_FIX is exactly 32, even in C.

76a7dc39e5 rescaler: add some SSE2 code 
The rounding and arithmetic is not the same as previously, to prevent overflow cases for large upscale factors.

We still rely on 32b x 32b -> 64b multiplies. Raised the fixed-point precision to 32b
so that we have some nice shifts from epi64 to epi32.
Changed rescaler_t type to 'uint32_t' in order to squeeze in all the precision required.

The MIPS code has been disabled because it's now out-of-sync. Will be fixed in
a subsequent CL when the dust settles.
~30-35% faster

d39dc8f3cc Create a WebPAnimDecoder API. 
This is designed for the simple use-case where one wants to decode all
frames one-by-one in order.

Also, use this API in anim_util library, which is in turn used by
anim_diff tool.

022d2f886c add SSE2 variants for alpha filtering functions 
The 'inverse' variants are harder to parallelize, since
the result of filtering is used for prediction.
The 'direct' way is relatively easier.

The heavy bottleneck left for optimization is still GradientUnfilter()
