Message:

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.
