The former approach to left the bin unfinished has some problems: the context
cannot be shared because the vaapidecode is unlinked in many cases, leading to
creating a VADisplay twice.
Initially the bin is fully functional, constructed as
(-----------------------------------)
| vaapidecodebin |
| (-------------) (-------) |
|<--| vaapidecode |--->| queue |--->|
| (-------------) (-------) |
(-----------------------------------)
When the context is shared and the VADisplay has VPP capabilities, before
changing to READY state, the bin is reconfigured dynamically, adding the
vaapipostproc element afeter the queue:
(--------------------------------------------------------)
| vaapidecodebin |
| (-------------) (-------) (---------------) |
|<--| vaapidecode |--->| queue |--->| vaapipostproc |--->|
| (-------------) (-------) (---------------) |
(--------------------------------------------------------)

Delay the bin configuration until changing to READY state. This is because we
should add the vaapipostproc element until the vaapidecode has emitted the
HAVE_CONTEXT message, so de gst_bin_add() could set the context set to
vaapipostproc.

A caps query can occur before the element has a display. In that case, the
element can return its pad's template. But when the element already has a
display, and the caps probe fails, the element shall return an empty caps, so
the auto-plug could try with another decoder.
If the element has a display and the caps probe works, then the computed caps
should be returned.

Caps query can happen before the element has a bus. The display creation should
be should occur on the context negotiation, when the bus is already configured.
Then at caps query no display should be created.
Instead of force the display creation, we graciously fail the allowed_caps()
creation.
This change only applies for vaapidecode and vaapisink. The vaapipostroc, as a
basetransform descendant, seems to be not affected by this, nor the encoders.

The current context query handling design is flawed: the function
gst_vaapi_reply_to_query() returns FALSE either if the query is not a
GST_CONTEXT_QUERY of if the query could not be handled correctly. But the
pad query function should handle differently each case.
This patch changes the gst_vaapi_reply_to_query() for
gst_vaapi_handle_context_query() and changes it usage in all the vaapi plugins
to match the correct context query handling.

Since the context messages are sync'ed, the display assignation happens in the
same thread, hence we can know if the display was found or not as soon we call

as a new parameter, the address of the plugin's display, and reports back if
the display was found and set.

The context structure is named "display" which is too generic. The contrary
happens, for example, with GstGL, what uses the same name as the context, and
its logs make more sense.
This patch renames the context structure with the same name as the
context, thus GST_PTR_FORMAT can pretty print it.
https://bugzilla.gnome.org/show_bug.cgi?id=757598
First, refactorized run_context_query() into _gst_context_run_query(), adding
a new parameter: the pad direction, in order to simplify the code.
Second, added a new helper function: _gst_context_query(), which is a generic
context query function. It isolates the operation of running the query and
sets the context if found, also it enhances the logs.
_gst_context_query() is similar to the one used in GstGL. Perhaps, in the
future this helper function will be merged into the core libraries of
GStreamer.
Finally, gst_vaapi_video_context_prepare() was rewritten to use
_gst_context_query().

Delaying the pool re-negotiation untill we push all decoded (and queued)
frames downstream. Otherwise for the multi-resolution videos, the
GstVideoVideoMemory will be having wrong resolution and which leads
to nasty behaviours, especially when using software renderers.
sample media file: RAP_B_Bossen_1.bin
case explained:
The first SPS Nal will report resoultion of 448x256 and having crop rectangles to
get the final resoultion 416x240.
Starting from 25 th frame, the resolution will change to 416x240. But parser
elements won't report this since the effective croped resolution is same in
both cases. Here the core libgstvaapi will detect this through it's internal
parsing and do all context/pool destory/reset stuffs. Also it will notify this
change to plugins in advance. But if the plugin try to do re-negotiaion of pool
immediately, this will not sync with the resolution of already decoded and queued
frames and which will lead to failure in gst_video_frame_map() in downstream(if we use the
software renderer). So we have to delay the pool renegotiation in vaapidecode,
untill we push all decoded frames downstream.

Currently we are sharing the input GstVideoCodecState with
GstVaapiDecoder(gst-libs/gst/vaapi) by just doing ref and unref for
each caps change. This is troublesome in many cases, for eg: if
resoultion changes with in a singe stream. Because, when ever there
is a resolution change, GstVideoDecoder will first change the Codec_state->caps
fields with new resolution, but since we are using the same codecstate (ref)
in gstvaapidecode.c, the caps check for input caps change will always fail.

There are sometimes that the VA-API display context is not shared among the
pipeline, but it is important to know it before going to READY state (when the
pipeline is already linked).
One instance of this case is this:
gst-launch-1.0 filesrc location=media ! decodebin ! vaapipostproc ! vaapisink
This patch adds a new function in gstvaapipluginutil called
gst_vaapi_create_test_display(). Its purpose is to create a disposable VA-API
display, which only will be used for verify if the VAEntrypointVideoProc is
available by the hardware. Afterwards, it should be unrefed.
If the vaapidecodebin is going to READY state, and the element still doesn't
know if VPP is available, the last resort is to create a new instance of the
VA-API display and test for it.
