As gstreamer-vaapi now only supports from GStreamer 1.6, this patch removes
all the old GStreamer version guards.

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.

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.

The use of gst_caps_is_always_compatible() for this optimization may lead to
false positives. It is better to stick to gst_caps_is_strictly_equal() to know
if it is required a re-negotiation.

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.
https://bugzilla.gnome.org/show_bug.cgi?id=753914
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.

Refactor the main vaapi caps strings into three macros:
GST_VAAPI_MAKE_SURFACE_CAPS, GST_VAAPI_MAKE_ENC_SURFACE_CAPS and
GST_VAAPI_MAKE_GLTEXUPLOAD_CAPS.
Those are in gstvaapipluginutil.h so all the elements could use them, instead
of re-declaring them every time.
No functional changes.

When seeking, the decoder is reset, but the buffer pool is not
re-negotiated, but in reset_full() the code forgets if the negotiated buffer
pool has the GLTextureUpload meta.
The decoder knows that GLTextureUpload meta was negotiated in
decide_allocation(), but this method is not called when seeking.

Fix link when building plugin elements without HEVC support. e.g. don't
try to call into gst_vaapi_decoder_h265_set_alignment() if there is no
support HEVC enabled in libgstvaapi.
Also, drop disabled codecs from static template caps. Add the missing
HEVC static template caps into vaapidecodebin too.
This a cosmetic refactor: gst_vaapidecode_internal_flush() removes its only
label; gst_vaapidecode_finish() is more readable and gst_vaapidecode_purge()
shares the same error message of gst_vaapidecode_internal_flush() when flush
fails.
Add the method gst_vaapidecode_purge(). This method releases the
flushed frames from the decoder.
This new method add more readablity to gst_vaapidecode_destroy()
When a frame is rejected by downstream, the message is logged twice. This
patch removes one of those logging messages.
Also, the reject of a frame doesn't mean an alarming error. This patch demotes
the log message from error to info.
We get one reference when the frame is passed to decode_handle_frame()
and create another one in gst_vaapi_decoder_push_frame().
Usually the frame is handled in gst_vaapidecode_push_decoded_frame().
Here the frame is always released twice:
gst_video_decoder_finish_frame() + gst_video_codec_frame_unref() or
gst_video_decoder_drop_frame() + gst_video_codec_frame_unref().
In gst_vaapidecode_reset_full() both references to the frame must be
released as well.

The purpose of gstcompat.h is to couple the API differences among
gstreamer-1.0 and gstreamer-0.10. Since gstreamer-0.10 is obsolete, the code
in this compatibility layer shall be removed.
Nevertheless, the gstcompat.h header should be kept, if new incompatibilites
appear in the future, but it shall live in gst/vaapi, not in gst-libs.
This patch removes the crumbs defined gstcompat.h and moves it to gst/vaapi.
In order to avoid layer violations, gstcompat.h includes sysdeps.h and all
the includes in gst/vaapi of sysdeps.h are replaced with gstcompat.h

Since GStreamer 1.2 the vmethod reset() in GstVideoDecoderClass was deprecated
and flush() was added.
This patch set the vmethod flush() if the installed GStreamer version is 1.2 or
superior. Otherwise, reset() is set.
v2: 1) In order to avoid symbol collision, the old method gst_vaapidecode_flush()
was renamed to gst_vaapidecode_internal_flush().
2) The new vmethod flush() always do a hard full reset.
v3: 1) Call gst_vaapidecode_internal_flush() first in flush() vmethod, in order to
gather all collected data with gst_video_decoder_have_frame()

GstVideoDecoder, the base class of vaapidecode, added support for
pad queries as virtual methods. This patch enables the use of that
support, while keeping support for lower versions of gstreamer.
This patch is important because GstVideoDecoder takes care of other
queries that might be important in the pipeline managing.
v2: 1) rebase to current master
2) fix indentation with gst-indent
3) simplify the patch layout
4) fix the context query
5) initialise the filter to NULL
6) improve the query log message for gst-1.2
