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.
This flag is obsolete.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.
GStreamer codecparsers-based decoders are the only supported decoders now.
Though, FFmpeg decoders are still available in gstreamer-vaapi 0.3.x series.
Bump GStreamer required version to 0.10.14, needed for
gst_element_class_set_details_simple().

Fix typo whereby plain VADisplay type was used instead of the GstVaapiDisplay
wrapper.

Try to gracefully abort when the HW does not support the requested
profile. There is no fallback unless profiles are correctly parsed
and matched through caps beforehand.
Rationale: playbin2 links all elements at run-time. Once vaapidecode
is created and a NEWSEGMENT event arrives, downstream element may not
be ready yet. So, delay this event until next element is chained in,
otherwise basesink could output "Received buffer without a new-segment.
Assuming timestamps start from 0".

Propagate "interlaced" caps downstream and set "tff" buffer flag
appropriately to output buffers for interlaced pictures.

Otherwise, the decoder would always create its own X display instead
of probing it from the downstream element, which is not reliable.
e.g. DISPLAY is not :0 or when running on Wayland.

With the new video/x-surface abstraction, we can't rely on having a VA
specific sink downstream. Also, there was no particular reason to do that.

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