Make sure the pool recognizes DMA_DRM caps and parses them into
GstVideoInfo that has GstVideoFormat corresponding to "drm-format"
in the caps.
Fixes
gst_video_frame_map_id: assertion 'info->finfo->format ==
meta->format' failed
Where the left side of the assertion was GST_VIDEO_FORMAT_DMA_DRM and
the right side was some GstVideoFormat converted from DRM fourcc.

Wrap dependencies add a ton of warnings with the latest GCC in Fedora
42. Squelch them by specifying that these dependencies are not
a part of the gstreamer project, and should be treated as system deps.
libsoup needs some porting work for the bump, and vorbis/lame are
already at their latest releases.

Some frames are dequeued with error flag, which may cause AV unsync if decoder
does not drop them as soon as possible. So add "output-error-dequeued" and
"capture-error-dequeued" signal for v4l2 to drop such frames.

Make sure to always update next_cluster_offset, if next cluster offset
isn't known set it to zero. If next_cluster_offfset isn't updated it will
be the same as current and if the cluster parsing fails the same cluster
will be parsed again leading to duplication of the data in the cluster.

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.

- LUT now supports various subsampling, interleaves, and bit depths.
- Replaces stride with GstVideoInfo pre_info to represent original data.
- Simplifies gst_row_align_buffer() with gst_video_frame_copy().

Since y4menc inherits from GstVideoEncoder, it negotiates upstream buffer pools
with GstVideoMeta support. Thus, certain decoders might use that meta for
frames with padded memory. Nonetheless y4menc assumes only linear memory video
frames, without padding.
This patch will copy frames using gst_video_frame_copy() if buffer has
GstVideoMeta or its video info is padded with its custom video info. Otherwise,
it ill call the agnostic gst_buffer_copy() for a shallow copy.

When dynamic caps change in the pipeline leads to a new buffer pool
getting negotiated, the change is not propagated to Qt6GLWindow, which
keeps using the old, now defunct, pool.
Unset current pool on Qt6GLWindow in decide_allocation(). This will
trigger a switch to the new pool inside create().
