Extensions can have a minimum set of dependencies (e.g. API version) and may
also be promoted to core in a later version. Don't explicitly enable extensions
that fail to meet their requirements or that have been promoted to the core API.

The instance API version supported may not be of the same version supported by
the device. It is possible that the function that is returned may be non-0
but not functional due to the requested API version of the instance limiting the
availability of calling the returned function.
Can be reproduced by running a pipeline with GST_VULKAN_INSTANCE_API_VERSION=1.1

Since Vulkan 1.1, the requested API version is the maximum API version that the
application is expecting to use. It is also possible for individual devices
(backed by potentially different drivers) may support a higher or lower API
version than the instance. Both cases (higher and lower) should be supported
and as such, it is not an error to request an API version that is larger than
the instance supported API version.

If the vulkan plugin was compiled against a newer version than the supported
vulkan runtime instance or device, then it was possible for format retrieval to
fail. Failure was due to unconditionally using newer extensions and features
without runtime checking them.

The API version exposed by a particular device can be completely different from
what is exported by the parent instance. Since Vulkan 1.1 it is also possible
to use newer device API than supported by the instance API version (with the
appropriate version checks).

The parent class will allow the handle to be reused at the end of the function.
If we are still modifying the released fence, then another thread can acquire
the fence while we are still clearing some of its data and produce a data race
or a leaked fence depending on which thread wins.

With this patch, configure time is identical no matter whether doc is
enabled or not.
The configuration files also now contain explicitly-listed sources with
no wildcards.
For the four libraries where hotdoc needs to use clang to generate the
documentation (as opposed to the rest of the libraries where hotdoc uses
the gir), the script will call pkg-config to determine the appropriate
C flags.
This means a side effect of this patch is that pkg-config files are now
generated for the gstadaptivedemux and gstopencv libraries.

This commit enables the usage of inline queries, if and only if, the
provided
pNext structure, in gst_vulkan_opeation_enable_query(), chains a
VK_STRUCTURE_TYPE_VIDEO_PROFILE_INFO_KHR typed structure.
Also it guards "gstvkvideo-private.h" include

It creates a new structure for passing the codec quality structure at _start(),
where it will be filled. The quality level can be set or changed according
encoder limits.
Later the quality level will be set at _update_session_parameters() and at each
frame encoding. That's why it has to be set at _start().

The algorithm for generating the current slot index is a simple round robin,
nonetheless it's not assured that the next slot index it's not still used by a
still living encode picture.
This new way holds an array with the still living encode pictures and the next
slot index looks for a released index in the array.
Its downside is deallocating a picture need to be removed from the array, so the
helper has to be passed to the uninit() function

In GStreamer that buffer information is decoupled, holding other structures to
describe the stream: GstCaps. So, to keep the GStreamer design this patch
removes these information from GstVulkanEncoderPicture and pass to
gst_vulkan_encoder_encode() a pointer to GstVideoInfo.

Instead of holding all headers in an external array and add them into the
bitstream buffer before the encoding operation, adding extra memory and extra
copy operations, the encoder picture should specify the offset where the Vulkan
will start to add the bitstream slices/frame, because the element has written
already the headers until that offset.

That's the number of references that gst_vulkan_encoder_encode() receives to
process, so it has to go as a parameter, because it's part of the reference
list, not of the picture.
This commit also modified unit tests accordingly.

The structure already stored the generic video capabilities and the specific
codec capabilities both for encoding an decoding. The generic decoder
capabilities weren't stored because it was only used internally in the decoder
helper object. Nonetheless, for the encoder, the elements will need the generic
encoder capabilities to configure the encoding. That's why it's required to
expose it as part of GstVulkanVideoCapabilities. And the generic decoder is
included for the sake of symmetry.
While updating the API vkvideoencodeh265 test got some code-style fixes.
