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().

gst-indent does not handle correctly some expression like function

This patch makes gst-indent to ignore the attributed function
declartion so the followed function definition is not mangled, such

Since gstvaapidisplay_glx.h do not expose gl.h/glx.h structures, it is not
required to include them in the header. It is not also required to include
them in gstvaapidisplay_glx.c, since gstvaapiutils_glx.h includes them and
exposes their structures (e.g. GLXPixmap).
Nonetheless, glext.h neither glxext.h are required to include, they are
already included conditionally by gl.h and glx.h, respectively.

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Support for GStreamer 1.2 is obsolete.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.

GST_CODEC_PARSER_* variables are defined if builtin codec parsers are disabled
when running configure.
Right now, libgstcodecparsers links only to libgstvaapi, but libgstvaapi_parse
need it if builtin codec parsers are disabled.
This patch adds GST_CODEC_PARSER_* variables to libgstvaapi_parse
compilation. If builtin codec parsers are enable, this variable is null, so it
should work using libgstvaapi, as normal.

Currently the H264 and H265 parsers look for MVC and SPS respectively, and
the required symbols for those were added in GStreamer 1.5
If we try to compile in GStreamer < 1.4, without enabling the builtin codec
parsers, the compilation fails, because the lack of those symbols.
This patch verifies if the installed H264 and H265 parsers have those symbols. If
they do not, the specific built in codec parsers are enabled and used.

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.

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.
