h264dsp: Factorize code into a new function, h264_find_start_code_candidate
This performs the start code search which was previously part of h264_find_frame_end() - the most CPU intensive part of the function. By itself, this results in a performance regression: Before After Mean StdDev Mean StdDev Change Overall time 2925.6 26.2 3068.5 31.7 -4.7% but this can more than be made up for by platform-optimised implementations of the function.
