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.

This new interface allows for upstream and downstream display sharing
that works in both static and dynamic pipelines.
