timecode: move timecode muxer options to metadata.

Browse Source 
Some demuxers set a timecode in the format or streams metadata. The
muxers now make use of this metadata instead of a duplicated private
option.

This makes possible transparent copy of the timecode when transmuxing
and transcoding.

-timecode option for MPEG1/2 codec is also renamed to -gop_timecode. The
global ffmpeg -timecode option will set it anyway so no option change
visible for the user.
