Simplify gst_vaapi_create_display() helper as gst_vaapi_display_XXX_new()
performs the necessary validation checks for the underlying VA display
prior to returning to the caller. So, if an error occurred, then NULL is
really returned in that case.
If the gstreamer-vaapi plug-in elements are built with GLX support, then
try to allocate a GstVaapiDisplayGLX first before resorting to a VA/X11
display next.

Port vaapidecode and vaapisink plugins to GStreamer API >= 1.0. This
is rather minimalistic so that to test the basic functionality.
Disable vaapiupload, vaapidownload and vaapipostproc plugins. The latter
needs polishing wrt. to GStreamer 1.x functionality and the former are
totally phased out in favor of GstVaapiVideoMemory map/unmap facilities,
which are yet to be implemented.

Fix gst_vaapi_apply_composition() to not fail if no overlay composition
was found. i.e. return success (TRUE). This was harmless though extra
debug messages are not nice.
This is a regression introduced by commit 95b8659.
Make gst_vaapi_reply_to_query() first check whether the query argument
is actually a video-context query, i.e. with type GST_QUERY_TYPE_CUSTOM.
Then, make sure vaapisink propagates the query to the parent class if
it is not a video-context query.
If vaapisink is in the GStreamer pipeline, then we shall allocate a
unique GstVaapiDisplay and propagate it upstream. i.e. subsequent
queries from vaapidecode shall get a valid answer from vaapisink.
Move display types from gstvaapipluginutil.* to gstvaapidisplay.* so that
we could simplify characterization of a GstVaapiDisplay. Also rename "auto"
type to "any", and add a "display-type" attribute.
vaapisink is now built with support for multiple display types, whenever
they are enabled. The new "display" attribute is used to select a particular
renderer.
This flag is obsolete. It was meant to explicitly enable/disable VA/GLX API
support, or fallback to TFP+FBO if this API is not found. Now, we check for
the VA/GLX API by default if --enable-glx is set. If this API is not found,
we now default to use TFP+FBO.
Note: TFP+FBO, i.e. using vaPutSurface() is now also a deprecated usage and
will be removed in the future. If GLX rendering is requested, then the VA/GLX
API shall be used as it covers most usages. e.g. AMD driver can't render to
an X pixmap yet.
This ensures the display name provided to gst_vaapi_display_*_new()
maps to the system defaults, instead of forcing "" that could be different
from the current DISPLAY name.
This new interface allows for upstream and downstream display sharing
that works in both static and dynamic pipelines.
