This gives a similar structure to libwebp and fixes a bug where passing NULL to SharpYuvInit() would unconditionally set optimized function pointers. SharpYuvInit() is left as an undocumented public function and SharpYuvGetCPUInfo is kept private to serialize updates to the pointer. Change-Id: Id72fbf3ba5b396367510e3bcd1ee2e4e11b95b8c
