We were previously always querying index 0, and while the number of planes per
buffer will never change, it seems more proper to query the right buffer rather
than always the first one.
This was found while reading strace logs, and wondering why the
V4L2_BUF_FLAG_MAPPED flag was present on all ¬0 indices even though that
happened before VIDIOC_EXPBUF.

- GstAnalyticRelationMeta is a base class for analytics
meta. It's able to store analytics results (GstAnalyticRelatableMtd)
and describe the relation between each analysis results.
- GstAnalysisRelationMeta also contain an algorithm able to explore
analysis results relation using a bfs.
- Relation(edge) between analysis results (vertice) are stored in an adjacency-matrix
that allow to quickly identify if two analysis results are related and by
which relation they related. It also work for indirect relation
and can provide the path of analysis results by which two
analysis results are related.
- One allocation per buffer to store analysis results. Here we rely on
the application to guess how much space will be required to store all
analysis results. This is something that could be improved
significantly but it's a starting point.
- Define common analysis results, classification, object-detection,
tracking that are subclass of GstAnalyticRelatableMtd. The also
provide exemple of how to extend GstAnalyticRelatableMtd to have them
benefit for the mechanim to express relation with other analysis
results.

During the video session memory allocation, the property flags can
be different from the expected ones, so do not expect all the
property flags and test it with G_MAXUINT32
It's failing with driver 525.47.26 and NVidia HW NVIDIA GeForce
RTX 3050 and 2060

Take the case into account when user filters have been set before the
source gets updated.
Note that the further linking of the filters, if present, happens below
in the `gst_camera_bin_check_and_replace_filter()` calls.
The audio filter is still affected by the same issue but left out for
now.

Even if IDXGIOutput6 says current display colorspace is HDR,
captured texture via IDXGIOutputDuplication::AcquireNextFrame()
is converted frame by OS unless we use IDXGIOutput5::DuplicateOutput1()
with DXGI_FORMAT_R16G16B16A16_FLOAT format, in order for captured
frame to be scRGB color space. Then application should perform
tonemap operation based on reported display white level, color primaries, etc.
Since we don't have any tonemapping implementation, ignores colorimetry
reported by IDXGIOutput6.

This is how it was documented and how it worked before the port to GstPlay.
Without this, applications expecting signals to be emitted directly
without anything running the main context will simply not receive any
signals.

d2d runtime seems to execute pending GPU command list
when DXGI ID2D1RenderTarget is being released, and it will invoke
d3d11 immediate context APIs. Should protect all rendering operations
and DXGI resources with lock.

The code seems to validate that the media-level fingerprint matches
the fingerprint of the previous media or of the whole session. There
is no such requirement in any RFC I found. The session-session one
is just meant to act as a fallback when there is no media-level
fingerprint.

This commit corrects the mapping relationship between RGB and BGR in GST and DRM.
The previous mapping was incorrect, causing potential color mismatches in the output.
The changes are as follows:
{WL_SHM_FORMAT_RGB888, DRM_FORMAT_RGB888, GST_VIDEO_FORMAT_BGR},
{WL_SHM_FORMAT_BGR888, DRM_FORMAT_BGR888, GST_VIDEO_FORMAT_RGB},
