2f9b765326 mpegvideoparse: Apply previous timestamp when there isn't any newer.
If the current incoming packet didn't carry a timestamp, but a
previous packet had one we didn't yet use, then apply that timestamp
to the next picture.
Fixes: #618336

721643431e mpegvideoparse: fix crash if downstream is unliked
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.

8144fee47c mpegvideoparse: Parse bitrate and emit as tag
This patch picks up the bitrate for the stream from the MPEG sequence
header and emits it as a tag on the source pad.

Fixes #599298.

0444aa3374 mpegvideoparse: Detect interlaced content and set it on outgoing caps.
I also added the parsing of all the other bits in the sequence extension
header in case we need it later.

Track segment events.
Do the first part of reverse playback by sending data between two
I-frames to the decoder.

ceba19f691 gst/mpegvideoparse/: Fix some silly bugs with calculating the guard sizes.
Original commit message from CVS:
* gst/mpegvideoparse/mpegpacketiser.c:
(mpeg_util_parse_extension_packet), (mpeg_util_parse_sequence_hdr),
(mpeg_util_parse_picture_hdr):
* gst/mpegvideoparse/mpegvideoparse.c:
(mpegvideoparse_handle_sequence), (mpegvideoparse_drain_avail):
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.

* gst/mpegvideoparse/mpegvideoparse.h:
Move the MPEG specific byte parsing into the mpegpacketiser code.
Add parsing of picture types, that just feeds into a debug message
for now.
Fix some 64-bit format strings.

* gst/mpegvideoparse/mpegvideoparse.vcproj:
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.
