This patch fixes CREATE_BUFS support for capture devices. Initially we
would only try and allocate more buffers when the copy threshold
is reached. When the threshold was not set (needed) it would never
happen. Another problem is that on capture side, acquire returns
filled buffer, hence need to pool. We need to set a special flag to
force allocation to happen.

When seeking or finding the previous keyframe, do
comparisons against targets and segments using composition time
to correctly decide which sample times match.
We used to setup an iterator with 1 GValue set with a NULL object
pointer which is not the normal way to do that. Instead we should make
sure that the first call to gst_iterator_next returns GST_ITERATOR_DONE.
Currently during header parsing, we scan through the entire file
and skip every moof+mdat chunk for fragmented mp4s, which makes
start-up incredibly slow. Instead, just stop at the first moof
chunk when have a moov, and start exposing the streams, so we
can go and start handling the moofs for real.
http://www.wavpack.com/file_format.txt:
"Both the APEv2 tags and/or ID3v1 tags must come at the end of the
WavPack file, with the ID3v1 coming last if both are present."
WavPack files that contain APEv2 tags at the beginning of the files
are unplayable on players that use FFmpeg (like VLC) and most other
software (except Banshee). Players that use libwavpack directly can
play the files because it skips the tags, but does not recognize the
tag data at that location.

When an caps-event is received, we must immediately change the crop
to videocrop correctly changed caps-event dimension, otherwise the
videocrop will first use the previous value of the crop that when
resizing video to a smaller resolution may cause an error.

Empty segments in an edit list have a media_start time of -1,
as they don't actually play any media. Allow for that when
aligning to the reference stream in reverse play.
This allow skipping buffer flagged with ERROR that has no payload.
This is typical behaviour when a recovererable error occured during
capture in the driver, but that no valid data was ever written into that
buffer. This patch also translate V4L2_BUF_FLAG_ERROR into
GST_BUFFER_FLAG_CORRUPTED. Hence decoding error produce
by decoder due to missing frames will now be correctly marked. Finally,
this fixes a buffer leak when EOS is reached.

If the v4l2 queue support dmabuf select this buffer pool mode
and update the query with allocator.
This patch only concern exporting dmabuf and not importing dmabuf
fd from downstream element.

Put a 0-byte at the end of the event string. Does not break ABI because
old depayloaders will skip the 0 byte (which is included in the length).
Expect a 0-byte at the end of the event string or a ; for old
payloaders.
