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.
```

[-Werror,-Wsingle-bit-bitfield-constant-conversion]

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.

Don't update info's size with the VA image reported data size for single plane
images, since drivers might allocate bigger space than the strictly required to
store the image, but when we dump the buffer as is (using filesink, for example)
the produced stream is corrupted. For multi-plane images video meta is required
to read/write them.
We updated info's size because gstreamer-vaapi did it too, but the reason to
update it there was for uploading and rendering surfaces (commit c698a015).
Furthermore, this patch adds an error message if the allocated data size for the
image by the driver is lesser than the expected because it would be a buggy
driver.
Fixes: #2959

Even if the segmentation feature value is not updated,
the parsed "segmentation_update_map" and "segmentation_temporal_update"
values should not be cleared as it's referenced during lower
level bitstream parsing. Also, don't use assert() in parser
unless it's clearly impossible condition.

If DPB is full already, GstH265Decoder::new_picture() might fail if
subclass uses fixed size picture pool and its size is equal to the DPB
size. Call the new_picture() after DPB is cleared in gst_h265_decoder_dpb_init()
