- Unset stream ids if a collection does not contain them
- Automatically select a default stream of a type if the stream type is
enabled but no stream is selected yet when receiving the stream collection
- Warn if there's a collection update via streams-selected and if there are
unexpected streams being selected, or actually selected streams not being
found
- Improve debug output a bit
Among other things this also makes sure that we don't forget a selected stream
id when disabling a track so that when enabling it again later the same one can
be enabled again.

As of Gst >= 1.24 we can just use GstVideoInfoDmaDrm APIs. Note
that SHM formats match DRM ones with only two exceptions.
No functional changes intended (for backporting) apart from
supporting a few more formats - those present in video-info-dma.c
but missing in the removed mapping.

Calculating intersection-of-union (IoU) is a very common operation used by
tensor-decoder handling tensors from vision models. Having this in a library
will improve maintainability and ease of writing tensor-decoder.
- Post-fix _uint: We might eventually want to handle different datatype that we
woule post-fix with _type

`gst/analytics/analytics.h` includes `gst/analytics/gstanalyticssegmentationmtd.h`,
which in turn `gst/video/video-info.h` but `gst-video-1.0` was only listed
in `Requires.private` field of `gst-analytics-1.0.pc`.
This would cause projects linking against `gst-analytics-1.0.pc` to fail to find
the headers when using alternative interpretation of pkg-config specification
that only considers private dependencies for include path during static builds,
such as the case e.g. on Nix.

The position is no longer duplicated across each pad and pad's segment. The
position is now only updated if it changes in the direction of playback so that
quickly repeated forward seeks do not cause the stream to seek from 0.
Reverse playback is expressly disallowed and an unnecessary extra flush of track
when seeking was removed.
A background task was added to periodically check on the current position and
the media source's buffering levels to keep the ready state up-to-date. The
source buffer no longer needs to trigger this update, it will happen whenever
the element state is READY or higher.
Finally, added proper error reporting when failing to push a buffer and improved
debug logging.

Since the sample map/track buffer now iterates samples in batches corresponding
to each coded frame group, the logic to feed the tracks is simpler. For media
without delta frames, it's a special case where the coded frame groups are all
size 1.
Now, all it does is skip data until the keyframe group containing the seek point
is found, then feed the track queue with the current sample and all future
samples until EOS or cancellation.
Resync of the iterator when the underlying track is modified is not necessary
because the outer loop attempts to resume feeding track data from where it was
interrupted in case of modification.
Also, the track feed task struct now holds a weak ref to its parent source
buffer to allow the task to cancel itself in any situation where the source
buffer is destroyed before the task is shut down.
Media parsing activity in the append pipeline no longer triggers ready state
recalculation on the msesrc since the msesrc now has a background task that
updates the ready state periodically when it's active which is more efficient in
cases where there is a high volume of samples being processed by the media
parser.
Finally, updated to adapt to track buffer API changes. Some functions previously
passed in a lower bound for sample timestamps. Now the source buffer is
responsible for clipping samples within a desired range of time.
