274551d450 mxfdemux: Store GstMXFDemuxEssenceTrack in their own fixed allocation
Previously they were stored inline inside a GArray, but as references to
the tracks were stored in various other places although the array could
still be updated (and reallocated!), this could lead to dangling
references in various places.

Instead now store them in a GPtrArray in their own allocation so each
track's memory position stays fixed.

Fixes ZDI-CAN-22299

Fixes https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/3055

This can happen when tracks aren't fully/properly detected due to new descriptors

206ed12368 mxfdemux: Handle sub-descriptor in generic descriptors
Specificied in S377-1 (2019) B.2 Generic Descriptor

This is one of the ways to store more "sub descriptors" for a single track

The segment was freed ... but not the contents :)

7ac4dd3d9d mxfdemux: Handle files produced by legacy FFmpeg
Until March 2022, the FFmpeg MXF muxer would write the various index table
segments with the same instance ID, which should only be used if it is a
duplicate/repeated table.

In order to cope with those, we first compare the other index table segment
properties (body/index SID, start position) before comparing the instance
ID. This will ensure that we don't consider them as duplicate, but can still
detect "real" duplicates (which would have the same other properties).

25b37c33dd mxfdemux: Fix issue with re-syncing
In case of re-syncing (i.e. moving to another partition to avoid too much of an
interleave), there was previously no checks to figure out whether a given
partition was already fully handled (i.e. when coming across it again after a
previous resync).

In order to handle this at least for single-track partitions, check whether we
have reached the essence track duration, and if so skip the partition.

3a77a3c696 mxfdemux: Don't double-increase track position
The essence track position should only be overriden if we sucesfully switched to
another position. In case of EOS we do not want to override it else we would
increase the track position *again* at the end of this function
