Move some of the logic in gst_vaapi_plugin_base_driver_is_whitelisted() to a
new function gst_vaapi_driver_is_whitelisted(), in this way, it can be used
when registering the plugin's feature set with the test VA display.

This patch tries to instantiate a GstVaapiDisplay when registering the plugin
features, if it fails, no gstreamer-vaapi element is registering.
The purpose of this patch is to avoid a situation where the user has
gstreamer-vaapi installed but their VA-API setup is not functional, which may
lead to unexpected behavior.

There are two main external dependencies that define the feature set of this
plugin: a) the kernel and b) the VA driver
This patch tracks both dependencies, if any of them change, GStreamer will
re-inspect the plugin.
The kernel is tracked through the device files /dev/dri/card*
The VA driver is tracked through the files VA_DRIVERS_PATH/*_drv_video.so,
where VA_DRIVERS_PATH is the one defined in libva package configuration. Also,
the environment variables LIBVA_DRIVERS_PATH and LIBVA_DRIVER_NAME are tracked
since they modify the driver lookup.
Additionally, the environment variable GST_VAAPI_ALL_DRIVERS is tracked too.

This reverts commit 1dbcc8a0e1 and commit
372a03a9e3.
While the dmabuf handle is exported, the derive image must exist, otherwise
the image's VA buffer is invalid, thus the dmabuf handle is never released,
leading into a file descriptors leak.
This is a fix for a regression of previous commit, which updates the filters
only when the property is set, because it is also required to update the
filter when the color balance interface change its values.
In case that sink caps and src caps are same, and no filtering parameter set,
pass-through mode is enabled.
If new filtering parameter is set during playback, it makes it reconfiguring,
so that pass-through mode is changed
In addition, updating filter is performed during reconfiguration, if needed.

A planar(or some other) buffer allocation may fail on the driver, then
the wayland connection becomes invalid, not able to send request or
receive any event. So we need to set up a new wayland connection if
there's an error detected on the cached wl_display.

In order to handle correctly seek and other operations, vaapiencode should
flush all the remaining data from the encoder without pushing it downstream.
This patch implements the flush() vmethod, only after of pausing the
source pad task, and restarting it again after the flush stop.

To avoid surface-exhausted situation during reverse playback,
drop frames except for key frame.
Also, to avoid the corruption of the parser state, flush() vmethod
doesn't destroy the VA decoder when playing in reverse.

The queue in GstVaapiDecode adds an extra reference to the frames. This patch
unref that extra reference earlier making the code simpler to follow.
https://bugzilla.gnome.org/show_bug.cgi?id=768652
Calling drain() vmethod means "decode any data it can at this point, but that
more data may arrive after". Hence, vaapidecode should check if there is data
in the output adapter and process them, without destroying the decoded picture
buffer (dpb).
Since this operation is done by gst_vaapidecode_internal_flush(), the operation
was refactored into a new function gst_vaapidecode_flush_output_adapter().
https://bugzilla.gnome.org/show_bug.cgi?id=768652
Calling flush() vmethod means "to flush all remaining data from the decoder
without pushing it downstream".
Nonetheless flush() is calling gst_vaapidecode_internal_flush(), which calls
gst_video_decoder_have_frame() if there is still something in the input
adapter, which may push buffers to downstream by calling handle_frame().
This patch changes this behavior by calling gst_vaapidecode_purge() rather
than gst_vaapidecode_internal_flush(), which does what we want: flushes the VA
decoder and releases all the rest of decoded frames.

This patch is a fix for my bad review of commit 6d73ca8d. The element should
be able to return the available raw caps handled by the VA display, but that
only should happen when there a VA display. If there's none, the element
should use the caps template.

Though USE_{JPEG,VP8,VP9,H265}_ENCODER macros definition depend on USE_ENCODER
macro, it is clearer to nest them, showing explicitly the dependency relation.
Under certain conditions the element might receive a positive context query
but without a context instance. This situation will lead to a segmentation
fault when traversing the context list in the pipeline.

Change defaults for max-bframes, cabac, and dct8x8 to be enabled
by default. This will cause the default profile to be high instead
of baseline. In most situations this is the right decision, and
the profile can still be lowered in the case of caps restrictions.

Without this, all dpb pictures are not released during flush,
because we used the global dpb_count variable for checking the
dpb fullness which get decremented in dpb_remove_index()
routine during each loop iteration.

If vaapisink received a caps query before getting a VA display, it returned
only the surfaces related caps. This behavior broke the autovideosink
negotiation.
This patch returns the pad's template caps if no VA display, otherwise the
caps are crafted as before.
