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

Due to race condition it was previously possible that
gst_element_add_pad was not completed for each RTSP stream before
signal 'no-more-pads' was emitted.
Race condition explained:
Lets say two RTSP streams are created: Video and Audio.
1. Callback new_manager_pad is called for the Video stream =>
stream->added=TRUE.
all_added=FALSE because both streams are not yet added.
Call gst_element_add_pad and emit signal 'pad-added' for Video stream.
2. Callback new_manager_pad is called for Audio stream =>
stream->added=TRUE.
all_added=TRUE because both streams are added.
Call gst_element_add_pad and emit signal 'pad-added' for Audio stream.
3. Lets say gst_element_add_pad for the audio stream completes before
the video stream. Since the audio stream already has all_added==TRUE
this will result in the signal 'no-more-pads' to be emitted before
gst_element_add_pad for the video stream is completed.
Solution is to move the logic that sets added=True and checks if all
streams are added to after gst_element_add_pad. This will make sure
signal 'no-more-pads' is not emitted until all code in
gst_element_add_pad is completed for all streams.

There was a race condition where the demuxer would seek back to beginning after
determining the duration and while that seek was in progress one pad would
attempt to push a new buffer downstream, leading to a critical warning in
gst_pad_push().

Devcontainer [1] is a popular container schema that makes
IDEs and tooling aware about the container image you want
to use and develop against.
The most popular implementation of devcontainer are Visual
Studio and VSCode and this allows us to have a out of the
box pre-defined and working build environment that is very
close to the environment CI runs against.
This also allows VSCode on Windows and Mac to setup a
Linux docker container (vm) to develop against if so
desired.

We install the rust toolchain, but then we have to manually
source it in CI since the headless containers skip over
the shell profiles that rustup typically uses.
Ideally we'd set these as variables in the main image, but
we don't have access to the buildah instance used in
ci-templates/cbuild.
However adding them to the toolbox image is good enough to
have the toolbox setup work ootb even if it doesn't call the
ci/scripts/source_image_env.sh script like the gitlab-ci jobs
will do.

Previously the script will give you a command like:
```
toolbox create gst-toolbox ..
```
Which is a bit redundant since we are already creating
toolbox, we don't need to label it as such.
Now instead use gst-$GST_UPSTREAM_BRANCH for the name,
so we will suggest gst-main and gst-1.24 instead

driftsamples currently uses the requested skew directly, even if it
exceeds cexternal.
Use the approach that skew_slaving uses to fix this. As a side benefit,
this makes the custom_slaving and skew_slaving code easier to compare.

This reverts commit 8c017c79c5736c9e45e635df210e08550287646d.
1.22 was the correct pkg-config version. It's only the subproject
version that was wrong. Since we bumped libva.wrap to 2.22 version, h266
is now always available when using the subproject.

The element should allocate GstFdMemory large enough to fit incoming
memory's size plus its potential offset.
Fixes "gst_memory_resize: assertion 'size + mem->offset + offset <=
mem->maxsize' failed".
Fixes an issue reproducible on Raspberry Pi 4 that results in a garbled
image on the receiver's end:
gst-launch-1.0 libcamerasrc ! unixfdsink socket-path=/tmp/socket
gst-launch-1.0 unixfdsrc socket-path=/tmp/socket ! autovideosink
