The incoming data has already been scanned in mpeg_packetizer_add_buf.
We can therefore stop scanning for picture data as soon as we've parsed
the header. Makes mpegvideoparse 2 times faster.
https://bugzilla.gnome.org/show_bug.cgi?id=648933
Use information from the gop header and picture
header to calculate the picture timestamp. (time_code
and temporal_reference) and adapt to upstream timestamps if
provided.
https://bugzilla.gnome.org/show_bug.cgi?id=632222
mpeg_packetizer_get_block() in some circumstances (here: if
downstream was unlinked) returns a block but does not set the
buffer causing mpegvideoparse_drain_avail() to cause invalid memory
access.
Fixes#619502.

Queue new-segment events and send them after caps have been
determined and set, so that the decoder will have been auto-plugged.

Fix some silly bugs with calculating the guard sizes.
Properly compare the old sequence header structure with the new one.
Don't error out on an invalid sequence - just ignore it.

Port mpeg1videoparse to 0.10 and give it rank SECONDARY-1, so
that it's below existing decoders.
Rename it to mpegvideoparse to reflect that it handles MPEG-1 and
MPEG-2 now.
Re-write the parsing code so that it collects packets differently
and timestamps Picture packets correctly.
Add a list of FIXME's at the top.
