0d5fad46cf 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.

c1cb86af5f fix 16b overflow in SSE2 
the 'accum' variable can be larger than 15b for large
rescale values.

Assert triggered:
 src/dsp/rescaler_sse2.c:249: RescalerExportRowExpand_SSE2: Assertion `v >= 0 && v <= 255' failed.
 src/dsp/rescaler_sse2.c:350: RescalerExportRowShrink_SSE2: Assertion `v >= 0 && v <= 255' failed.

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

38410c082f [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.

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.
