Timecode input/output

--tcfile-in allows a user to specify a timecode v1 or v2 file to override input timestamps.
Useful for dealing with VFR input, especially when FFMS/LAVF support isn't available.
--tcfile-out writes a timecode v2 file containing the timecodes of the output file.
New --timebase option allows a user to change the stream timebase.
Intended primarily for forcing timebase with timecode files if necessary.
When using --seek, note that x264 will seek in the timecode file as well.
