f66955de5f WEBP_REDUCE_CSP: restrict colorspace support 
only supported ones are: RGBA/BGRA/rgbA/bgrA (decoder)
as well as: WebPPictureImportRGB/RGBX/RGBA (encoder).

(note: extras/get_disto is affected too)

c10a493caf vwebp: disable double buffering on windows & mac 
this results in flickering with animated webp + alpha. disabling the
option is a workaround to restore the behavior to the previous release.

b94cee98fb dec_sse2: remove HE8uv_SSE2 
with gcc-4.8, clang-4.0.1/5 this is no faster (actually up to 2x slower)
than the code generated for memset (0x01010... * dst[-1]). shuffles in
sse4 recover a bit, but performance is still down.

This is 10% faster, for some reasons.

SSE2 version should be straightforward.

04b029d236 WebPMemToUint32: remove ptr cast to int

the input ptr to anything aside from its type is unnecessary for memcpy
and is contrary to the intent of this function.

b7971d0e22 dsp: avoid defining _C functions w/NEON builds 
when targeting NEON C functions with NEON equivalents won't be used, but
will contribute to binary size. the same goes for sse2, etc., but this
change is primarily concerned with binary sizes for android arm targets.

note '-noasm' or otherwise modifying VP8GetCPUInfo will have no effect
on the use of NEON functions.

this decision can be overridden by defining WEBP_DSP_OMIT_C_CODE to 0.
