treat an ANMF chunk containing multiple VP8/VP8L file as malformed.
fixes a WebPMuxImage::img_ leak.
Though the invalid free in #9106 was avoided in (ubsan):
be738c6d muxread,ChunkVerifyAndAssign: validate chunk_size
that file would still cause a leak similar to #9099.

previously when adjusting size down based on a smaller riff_size the
checks were insufficient to prevent 'size -= RIFF_HEADER_SIZE' from
rolling over causing ChunkVerifyAndAssign to over read. the new checks
are imported from demux.c.

with loop_compatibility disabled (the default), non-zero loop counts
will be incremented by 1 for browser rendering compatibility. the max,
65535, is a special case as the muxer will fail if it is exceeded; avoid
increasing the limit in this case. this isn't 100% correct, but should
be close enough given the high number of iterations.

this results in flickering with animated webp + alpha. disabling the
option is a workaround to restore the behavior to the previous release.

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.

Rewrote WebPPictureHasTransparency() to use them (even for argb).
This is 10% faster, for some reasons.
SSE2 version should be straightforward.
Removes a TODO.

The WebPDemux and WebPAnimDecoder APIs are provided for the purpose of
