Move code around in a more logical way. Introduce GST_VAAPISINK_CAST()
helper macro and use it wherever we know the object is a GstBaseSink or
any base class. Drop explicit initializers for values that have defaults
set to zero.
Introduce new backends vtable so that to have clean separation between
display dependent code and common base code. That's a "soft" separation,
we don't really need dedicated objects.

Support for X11 "synchronous" mode was never implemented, and was only
to be useful for debugging. Drop that altogether, that's not going to
be useful in practice.

Rendering with GLX in vaapisink is kind of useless nowadays, including
OpenGL related fancy effects. Plain VA/GLX interfaces are also getting
deprecated in favor of EGL, or more direct buffer sharing with actual
GL textures.
Should testing of interop with GLX be needed, one could still be using
the modern cluttersink or glimagesink elements.

Allow dynamic changes to the window, e.g. performed by the user, and
make sure to refresh its contents, while preserving aspect ratio.
In practice, Expose and ConfigureNotify events are tracked in X11
display mode by default. This occurs in a separte event thread, and
this is similar to what xvimagesink does. Any of those events will
trigger a reconfiguration of the window "soft" size, subsequently
the render-rect when necessary, and finally _expose() the result.
The default of handle_events=true can be changed programatically via
gst_x_overlay_handle_events().
Thanks to Fabrice Bellet for rebasing the patch.

If a multiview stream is decoded, multiple view components are submitted
as is downstream. It is the responsibility of the sink element to display
the required view components. By default, always select the frame buffer
that matches the view-id of the very first frame to be displayed.
However, introduce a "view-id" property to allow the selection of a
specific view component of interest to display.
This maps GstVideoColorimetry information in vaapisink's sinkpad caps
to GST_VAAPI_COLOR_STANDARD_* flags, if per-buffer information was not
available.

Factor out propose_allocation() hooks, creation of video buffer pool
for the sink pad, conversion from raw YUV buffers to VA surface backed
buffers. Update vaapidecode, vaapiencode and vaapipostproc to cope
with the new GstVaapiPluginBase abilities.
Move common VA display creation code to GstVaapiPluginBase, with the
default display type remaining "any". Also add a "display-changed"
hook so that subclasses could perform additional tasks when/if the
VA display changed, due to a new display type request for instance.
All plug-ins are updated to cope with the new internal APIs.
Introduce a new GstVaapiPluginBase object that will contain all common
data structures and perform all common tasks. First step is to have a
single place to hold VA displays.
While we are at it, also make sure to store and subsequently release
the appropriate debug category for the subclasses.
Handle raw video buffers that were not created from a VA video buffer
pool. Use the generic GstVideo API to copy buffers in GStreamer 1.0.x
builds instead of the GstVaapiUploader.

Other GStreamer sinks, like xvimagesink, have a force-aspect-ratio property,
which allows you to say that you don't want the sink to respect aspect
ratio. Add the same property to vaapisink.

Now that VA/GLX capable buffers are generated by default on X11, thus
depending on a VA/GLX display, we stil want to use vaPutSurface() for
rendering since it is faster.
Anyway, OpenGL rendering in vaapisink was only meant for testing and
enabling "fancy" effects to play with. This has no real value. So,
disable OpenGL rendering by default.
Introduce a new configure option --with-gstreamer-api that determines
the desired GStreamer API to use. By default, GStreamer 1.0 is selected.
Also integrate more compatibility glue into gstcompat.h and plugins.
Use new GstVaapiVideoBufferPool to maintain video buffers. Implement
GstBaseSink::propose_allocation() to expose that pool to upstream
elements; and also implement GstVideoDecoder::decide_allocation() to
actually use that pool (from downstream), if any, or create one.

Add new GstVaapiUploader helper to upload raw YUV buffers to VA surfaces.
It is up to the caller to negotiate source caps (for images) and output
caps (for surfaces). gst_vaapi_uploader_has_direct_rendering() is available
to help decide between the creation of a GstVaapiVideoBuffer or a regular
GstBuffer on sink pads.

Keep VA surface proxy associated with the surface that is currently
being displayed. This makes sure that surface is not released back
to the pool of surfaces free to use for decoding. This is necessary
with VA driver implementations that support rendering to an overlay
pipe. Otherwise, there could be cases where we are decoding into a
surface that is being displayed, hence some flickering.
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.
Fix gst_vaapisink_xoverlay_set_window_handle() when it is called before
caps got negotiated. Besides, when a foreign window is provided by the
user, so should the render rect.
