59579a9cb3 plugin: remove custom GstGL context handling
Instead of using our own context handling for looking for GstGL
parameters (display, context and other context), this patch changes
the logic to use the utility function offered by GstGL.

8f5933cd80 vaapivideocontext: only vaapisink process app context
gst.vaapi.app.Display context is made for applications that will
provide the VA display and the native display to used by the
pipeline, when are using vaapisink as overlay. There are no use
case for encoders, decoders, neither for the postprocessor.

In the case of the vaapisink, it shall query for gst.vaapi.Display
upstream first, and then, if there is no reply,
gst.vaapi.app.Display context will be posted in the bus for the
application. If the application replies, a GstVaapiDisplay object
is instantiated given the context info, otherwise a
GstVaapiDisplay is created with the normal algorithm to guess the
graphics platform. Either way, the instantiated GstVaapiDisplay
is propagated among the pipeline and the have-message bus message.

Also only vaapisink will process the gst.vaapi.app.Display, if
and only if, it doesn't have a display already set. This is
caused because if vaapisink is in a bin (playsink, for example)
the need-context is posted twice, leading to an error state.

6b2b1294f8 vaapivideocontext: return the direction of gl context
In function gst_vaapi_find_gl_context() add a direction parameter to
return back the direction where the GstGL context was found.

This is going to be useful when checking if downstream can import
dmabuf-based buffers.

b8265db260 videocontext: support "gst.vaapi.app.Display" context
Through "gst.vaapi.app.Display" context, users can set their own VADisplay
and native display of their backend.

Attributes:
- display : pointer of VADisplay
- x11-display : pointer of X11 display (Display *), if they're using.

This patch creates GstVaapidisplayX11 if information provided through
"gst.vaapi.app.Display"

604986749e plugins: add gst_vaapi_plugin_base_find_gl_context()
Using the GstContext mechanism, it is possible to find if the pipeline
shares a GstGLContext, even if we are not to negotiating GLTextureUpload
meta. This is interesting because we could negotiate system memory caps
feature, but enable DMABuf if the GstGLContext is EGL with some extensions.

ed280f5b84 vaapivideocontext: add gst_vaapi_video_context_set_display()
This function set the display to an already created context. This function is
going to be used later.

Also, gst_vaapi_video_context_new_with_display() now uses this function.

ef3fb4afaf plugins: check if display is set in sync
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.

3024640d4f plugins: remove gstreamer-0.10 crumbs
GstVideoContext was used in gstreamer-0.10, which is not supported anymore.
Still, its definition was still in the code. This patch removes it.

8b36e25f47 Removal of gstreamer-1.0 support
The support for GStreamer 1.0 has been obsoleted in 0.5.10 release.
GStreamer 1.2 is the a minimal requirement for building the gstreamer-vaapi.

This patch removes all the pre-processor conditional code compilation guarded
for gstreamer-1.0.

Thus, all the video converters were removed too.

c67b783275 plugins: add compat layer for GstVideoContext.
Add thin compatibility layer for the deprecated GstVideoContext API.
For GStreamer API >= 1.2, this involves the following two functions:
- gst_vaapi_video_context_prepare(): queries if a context is already
  set in the pipeline ;
- gst_vaapi_video_context_propagate(): propagates the newly-created
  context to the rest of the pipeline.
