GstVideoEncoder, the base class of vaapiencode, added support for pad queries
as virtual methods since gstreamer 1.4. This patch enables those vmethods,
while keeps support for previous versions of gstreamer.
This patch is relevant since GstVideoEncoder takes care of other queries that
we are currently ignoring.

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
for it.
In order to take advantage of it, gst_vaapi_video_context_prepare() receives,
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.

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().

Though caps features are supported since GStreamer 1.2, there are some
issues with the features caps negotiation in that version. Nonetheless,
those issues are fixed in GStreamer 1.4. So, the memoy:VASurface caps
feature negotiation is relaxed for GStreamer 1.4.
The guard is the same as in vaapisink's caps template.

Instead of calling gst_vaapi_find_preferred_caps_feature(), which is
expensive, we check the caps from the allocation query, to check the
negotiated feature.
In order to do this verification a new utility function has been implemented:
gst_vaapi_caps_feature_contains().
As this new function shared its logic with gst_caps_has_vaapi_surface(), both
have been refactorized.

Support for GStreamer 1.2 is obsolete. i.e. it is no longer supported.
Our goal is to support the last two stable versions of GStreamer which
are 1.4 and 1.6 at the moment.
We still keep the 1.2 specific codes until the next gstreamer-vaapi-0.7
release and will get rid of those in 0.8.
gst_buffer_copy_deep() was added in GStreamer 1.5. If want to use it we should
add an implementation if gstreamer-vaapi is linked to previous versions.

When the GstVaapiParserInfoH264 is allocated, the memory is not initialized,
so it contains random data.
When gst_h264_parser_parse_pps() fails, the PPS structure keeps slice_group_id
pointer uninitialized, leading to a segmentation fault when the memory is
freed.
This patch prevents this by initializing the slice_group_id before the PPS
parsing.
