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 is a binary compatible release.
* lossy encoder improvements to avoid chroma shifts in various circumstances
(issues #308, #340)
* big-endian fixes for decode, RGBA import and WebPPictureDistortion
Tool updates:
gifwebp, anim_diff - default duration behavior (<= 10ms) changed to match
web browsers, transcoding tools (issue #379)
img2webp, webpmux - allow options to be passed in via a file (issue #355)

the interpretation of a 0 duration depends on the implementation;
merging of multiple frames isn't guaranteed, some may enforce a minimum
duration.

this internalizes the init checks and provides stronger synchronization
with pthreads when available while still allowing VP8GetCPUInfo to be
modified (mostly for testing purposes). windows is left as is since a
critical section or mutex would cause a leak.

-> fall back to C implementation in this case for now

Also fix the bug where near lossless was not used
and allow examples to be built by default.
