If the pad is already fixed the caps query have to be reply with the
current fixed caps. Otherwise the query has to be replied with the
autogeneratd src caps.
This path fix this by falling back to the normal caps query processing
if the pad is already fixed. Otherwise it will fetch the allowed src
pad caps.

Since commit 9f627ef2 if the user sets level in the encoder src caps
the caps negotiation is rejected.
But since the same commit the same encoder set the autoconfigured
level in caps. Some change in the base class might fixed the operation
order so now the caps are set and later negotiated.
This patch removes the level check.

This code path is used when frames are rendered as textures through
GstVideoGLTextureUploadMeta with EGL, mainly under Wayland.
Originally the EGLImage was exported as GEM, which was handled by
Intel drivers, but Gallium ones cannot create VA surfaces from
GEM buffers, only DMABuf.
This patch checks the memory types supported by VA driver to choose
the render the EGLImages from GEM or DMABuf, because GEM is still
better where supported.
DMABuf is well handled either by intel-vaapi-driver and gallium.

Since nobody uses it, just remove it.
Thus extract_allowed_surface_formats() is refactored to attend only
gst_vaapi_plugin_base_get_allowed_sinkpad_raw_caps().
Now a surface is created when the image chorma is different from the
previous one. And if the driver has the quirk, it outputs all the
supported image formats without trying them.
Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer-vaapi/-/merge_requests/381>
The try-and-error approach for getting the possible image formats from
a surface has brought several problems in different drivers, from
crashes to drop in performance.
Instead of that we change the algorithm to determine the possible
image formats based in the surface chroma: only those available image
formats with same chroma are exposed as possible raw caps.
Do this is important to avoid performance degrading in raw sinks
which doesn't handle NV12 but it does YV12 or I420.

Some buffers and the associated FrameState state may still be pending at
that point. If the wayland connection is shared, then messages for the
buffer may still arrive. However, the associated event queue is already
deleted. So the result is a crash.
With a private connection the associated memory is leaked instead.

On Wayland, The whole gtk window is one Wayland surface. So
gtk_widget_get_window() must be called on the top-level widget.
For any other widget the following gdk_window_ensure_native() may create a
new top-level Wayland surface that is never visible.
As a result, the coordinates passed to
gst_video_overlay_set_render_rectangle() must be relativ to the top-level
window. Otherwise the video is placed incorrectly.

gst_vaapi_window_wayland_set_render_rect() may be called from an arbitrary
thread. That thread may be responsible for making the window visible.
At that point another thread will block in gst_vaapi_window_wayland_sync()
because the frame callback will not be called until the window is visible.
If that happens, then acquiring the display lock in
gst_vaapi_window_wayland_set_render_rect() would result in a deadlock.
Cache the size of the opaque rectangle separately and create the opaque
region right before applying it to the surface.

Implements new vmethod gst_vaapi_window_set_render_rectangle,
which is doing set the information of the rendered rectangle set by
user.
This is necessary on wayland at least to get exact information of
external surface.
And vaapisink calls this when gst_video_overlay_set_render_rectangle is
called.

The Wayland sub-surfaces API is used to embed the video into an application
window.
See Appendix A. Wayland Protocol Specification as the following.
"""
The aim of sub-surfaces is to offload some of the compositing work
within a window from clients to the compositor. A prime example is
a video player with decorations and video in separate wl_surface
objects.
This should allow the compositor to pass YUV video buffer processing to
dedicated overlay hardware when possible.

Some context does not report any valid format that we can support.
For example, the HEVC 444 12 bits decoder context, all the formats
it reports is not supported now, which make the formats list a NULL
array. We should check that pointer before we use it.

In h265, bigger profile idc may not be compatible with the small profile
idc. And more important, there are multi profiles with the same profile
idc. Such as main-422-10, main-444 and main-444-10, they all have profile
idc 4.
So recording the max profile idc is not enough, the encoder needs to know
all allowed profiles when deciding the real profile.

In h265, higher profile idc number does not mean better compression
performance and may be not compatible with the lower profile idc.
So, it is not suitable to find the heighest idc for hw to ensure the
compatibility.
On the other side, when the entrypoint of the selected profile is valid,
it means the hw really support this profile, no need to check it again.
