  lavf: remove unreliable timestamp guessing heuristic

Conflicts:
	libavformat/utils.c

Not merged, as the change breaks ABI by removing a field from the middle
of AVStream.
Also, if you have files that decode better or worse without this code please
open a ticket on trac. If the timestamp code turns out useless it of course
should be removed.

  h264_ps: when parsing a VUI fails, only abort when explode is set

Merge only for metadata, ignoring invalid data can put the context
into an invalid state and can possibly be used for remote code
execution exploits.
Also we support all non standard VUIs that have been reported so
ignoring parsing failure makes no sense for us unless theres
some issue that has not been reported
