71c39a06c8 webp-container-spec: correct frame duration=0 note 
the interpretation of a 0 duration depends on the implementation;
merging of multiple frames isn't guaranteed, some may enforce a minimum
duration.

d77bf512bd add WEBP_DSP_INIT / WEBP_DSP_INIT_FUNC 
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.

978eec2507 [CFI] Remove function pointer casts 
Control Flow Integrity [1] indirect call checking verifies that function
pointers only call valid functions with a matching type signature. This
change eliminates function pointer casts that were causing cfi-icall
failures.

e03f0ec319 sharp_yuv: use 14b fixed-point precision for gamma 
Output is <.1% difference in size, randomly.

Speed is 30-50% faster (-m 0 -sharp_yuv).
It also gives the exact same output on ARM and x86, because floats
are no longer used.
