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.

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},

Instead of guessing the DRM format and modifier, pass a DRM video info to
gst_va_dmabuf_memories_setup().
Still, it checks for the DRM parameters in DRM info, if they are not available,
as in the case of V4L2 buffers, the part of the video info is used.
This is an API breakage, but since the plugin is still in stage, it's still
allowed.

To import DMAbufs we used VASurfaceAttribExternalBuffers which works, but it's
not specific for DRM PRIME 2, since it lacks of many metadata. This patch
replaces VASurfaceAttribExternalBuffers with VADRMPRIMESurfaceDescriptor in
va_create_surfaces().
Still, this patch assumes linear modifier only.
The hack for RGB surfaces in I965 driver was pushed down into
va_create_surfaces() to avoid handling both structures.

Now that nvidia-vaapi-driver appeared and isn't yet supported by GstVA, we've to
add an allowed list of supported drivers.
This patch implements it adding a environment variable to disable this driver
check: GST_VA_ALL_DRIVERS

Suppose you have a project where GStreamer and wayland-protocols are
pulled in as dependencies via .wrap files. In that case, Meson's setup
step will fail for gst-plugins-bad with the message "Sandbox violation:
Tried to grab file viewporter.xml outside current (sub)project." To
avoid this exception, one should use Meson's `files` and `join_paths`
functions. The suggested solution is identical to how GTK 4 processes
Wayland files.

When hotdoc documentation is enabled and opencv plugin is set as
auto-detected, but the library isn't installed, meson configuration fails
with this message:
../subprojects/gst-plugins-bad/docs/meson.build:139:21: ERROR: Unknown variable "gstopencv_dep".
This patch fixes this case defined gstopencv_dep as disabler() when
dependencies aren't found.

Current codes try derive image in _update_image_info first, if
derive returns no error, the va_allocator->info is the one from derived
image, but in va_map_unlocked, we disable derive manner for d3d backend
because it doesn't seem to work, this will cause issue for d3d path,
i.e. possibly using derived info in va_get_image to do mapping...
This patch disables derive image for d3d backend in _update_image_info,
to ensure we only use info from va_create_image for d3d path.

An operation is an arbitrary amount of work to be executed on the host, a
device, or an external entity such as a presentation engine.
The purpose of this object is to help on the operation's synchronization
through declaring explicit execution dependencies, and memory dependencies
between two sets of operations defined by the command’s two synchronization
scopes.

While VkPipelineStageFlags is an enum (arguably backed as uint32 in 32bit
platforms), VkPipelineStageFlags2 is a redefinition of guint64; likewise for
VkAccessFlags and VkAccessFlags2.
This patch types both members in GstVulkanBarrierMemoryInfo as guint64 for
compatibility, so it could be used with or without synchronization2 vulkan
extension.

Previously we were checking for opencv dep in 2 different places,
and the checks would vary in terms of how complex and exhaustive
they were.
Move the check into the libs module and reuse the result later on.

This field is used to store gbooleans (which are ints) but if it's
a :1 bit depth assigning ints to it changes it's value as the only
valid values are -1 and 0.
Make it a guint instead so the cast would be correct.
```

The v4l2codecs H.265 decoder uses the
GstH265SliceHdr::entry_point_offset_minus1 array so make sure that it is not
freed before decoding the frame.
Before this patch, some H.265 input would segfault in
gst_v4l2_codec_h265_dec_fill_slice_params() when executing the line:
guint32 entry_point_offset = slice_hdr->entry_point_offset_minus1[i] + 1;
Make sure that the array is not freed before using it.
