Avid uses a custom essence container UL and custom essence element keys
that are fortunately compatible with the generic container essence
elements. Partially fixes bug #561922.
Avid usually uses a custom essence container label for the essence
descriptors and stores the actual codec that is used inside the
picture essence coding field (and for sound probably in the sound
essence coding field but I have no sample files with sound).
Partially fixes bug #561922.
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.
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.

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.

table (including body sid) to the start of partition packs.
Later this will be used for reading all index table segments of
the complete file efficiently.

Use guint instead of guint64 or gsize for all buffer sizes and
use correct format strings for them. Only local tag set sizes
are still guint16 as they can't be larger.
Only allow KLV packets of sizes below 1<<32 as GStreamer only uses
guint for buffer sizes. The MXF standard allows packet sizes up
to 1<<64.
