Generate an index table for essence streams during playback
and make sure that only the correct essence elements are
used for played tracks.
Make it possible to have one essence stream used in multiple
playback tracks.
Fix some minor bugs.
When parsing an index table segment without a valid
primer pack in this partition only parse the static
local tags and ignore all dynamic ones.
This allows us to use index table segments in some
broken files.
Add an abstraction to represent essence tracks and
use this everywhere. This will later be used to keep
track of positions and to generate/handle seek tables.
Some random cleanup and renaming.
Header metadata is finished after partition.header_byte_count
bytes after the first byte of the primer pack are handled.
After this there can only be index table segments, filler packets,
essence or the start of the next partition.
This fixes playback of some files that have non-standard metadata
packets in the header metadata.
Store all partitions & primer packs in memory for faster access.
This is later needed for fast seeking.
Pre-fill the list of partitions with the content of the random
index pack.
Don't parse metadata of an partition twice.
Store the MXF metadata in a hash table, keyed by the
instance UID. This simplifies resolval of the metadata
and makes looping over all metadata sets unnecessary
in most cases.
Additionally parse metadata always. If we already have
a metadata set with the same UID replace it only if
the new metadata set is from a later offset. This
fixes metadata parsing of files where following partitions
don't have a complete copy of the previous metadata.

Don't allow negative or zero edit rates to prevent division
by zero and we support negative edit rates anyway.

Implement support for OP2a/b/c and OP3a/b/c, i.e. tracks with
more than a single component. This currently only works for
the case where the components are stored in playback order
in the file.
Set some more default/distinguished values for the structural
metadata.
Make some types more strict by choosing the correct subclasses.
Set DISCONT flag on buffers after a component switch.
Take the last partition from the random index pack for the footer
partition of the header partition doesn't reference the footer
partition. This gives us the final structural metadata for
some more files in the beginning.

set rate and channels and use this for all sound essence.
Give some debug output when setting picture essence caps with
invalid descriptor values.
Fix height calculation from the frame layout a bit more and
add a TODO to check if it's really correct now or if it needs
more fixing (especially, does the framerate need adjustments?).
Original commit message from CVS:
* gst/mxf/mxfdemux.c: (gst_mxf_demux_chain):
In push mode skip the run in again if we get buffers with
an offset before the run in. This can happen on seeks for example.
