decoder: h264: add initial support for repeat-first-field (RFF) flag.

Browse source 
Use the SEI pic_timing() message to track and propagate down the repeat
first field (RFF) flag. This is only initial support as there is one
other condition that could induce the RFF flag, which is not handled
yet.
