- Add case where we have element in subset that are equal to element in
superset. In this case subset is still a subset if at least one element is a
subset of the corresponding element in superset.
- clarify gst_value_is_subset inline documentation
- Add helper VALUE_TYPE_SINGLETON (type) to identify GType that represent a
value that is not a collection.
- Fixed issue in gst_value_is_subset_array_array (<1, 2, 3>, <0, 1, 4, 2, 3>)
would have returned TRUE because because the alignment of the subset could be
done multiple times. Now once alignment of set as been done once, everything
else in the superset need to be a subset of corresponding element without
interuption. is_subset (<1, 2, 3>, <0, 1, 2, 3>) => TRUE, but is_subset (<1,
2, 3>, <0, 1, 4, 2, 3>) => FALSE.
- If both array are fixed value and we perform a is_subset on them, both value
can't be equal to be considered subset. (For consistency with other fixed
values)
- Define gst_value_subtract (singleton, array) and
gst_value_subtract (array, singleton), to allow a gst_value_is_subset
(singleton, array) and gst_value_is_subset (array, singleton). General
case of gst_value_is_subset (v1, v2) use gst_value_subtract (v1, v2) and
gst_value_subtract (v2, v1) to evaluate _is_subset(), therefore we need these
for is_subset() operation that involve singleton and array.
Note gst_value_subtract (array, array) is not implemented but this case is not
require by gst_value_is_subset () and as it has a direct handling. Warned if
the case is used.

When doing direct dmabuf upload, we rely on the GL stack for doing the color
transformation. The caps we transform from GL to DMABuf are always with a format
of RGBA. Instead of listing all GstVideoFormat and translating them back into
DRM formats, simply list all supported DRM format for the context.
This enable rendering DRM formats that don't have an shader based emulation
implemented such as NV15.

The transformation was fuzzy, adding random modifiers to the list. Use the newly
introduce helpers from 1.26 to precisely convert GStreamer formats to a DRM
fourcc and modifier pair and vice-versa.
This fixes support for formats that have a GstVideoFormat value and requires a
modifier.

It is not possible to do frame cropping when DMABuf caps feature is negotiated.
The VideoInfo size is zero, resulting in empty destination buffers, and video
convert library may not understand what the format actually is.

If the conformance window does not requires cropping the top or left of the
window, we can use GstVideoMeta to crop in a zero-copy fashion. If a copy
is needed, the frame copy can also handle it, and is a lot faster.

Similar to what qtdemux does in `gst_qtdemux_stream_update_segment()`,
in which case we want to resend tags according to our position.
By setting the changed flag for all stream tags we ensure they will all
be (re-)send as we progrees.
This notably ensures that rotation tags are not lost when video players
finish playback and jump back to the beginning of a video.

Similar to and inspired by glimagesink, xvimagesink and others.
The waylandsink never transform the buffer in any way but delegates this to the
Wayland compositor with the Wayland buffer transform API.
Rotation and window size are already supported, so this just changes the video
surface geometry that is communicated to the Wayland compositor.

Cleans up the code and fixes two issues:
- If there are no streamheaders in the caps but we have `HEADER`
buffers, it would run `gst_buffer_list_foreach` with `self->headers`
being `NULL`.
- The code forgot to unmap the buffer if it decided to ignore it.
