03e96f3ceb gtkglsink: expose the created display and context correctly
1. Propagate the GstGLDisplay we create
2. Add the created GstGLContext to the propagated GstGLDisplay

Otherwise with multi-branch GL pipelines involving gtkglsink, things
will fall apart and errors will be genarated somewhere.

2fd84a6c86 gl: do not include GL headers in public gstgl headers
Except for gst/gl/gstglfuncs.h

It is up to the client app to include these headers.
It is coherent with the fact that gstreamer-gl.pc does not
require any egl.pc/gles.pc. I.e. it is the responsability
of the app to search these headers within its build setup.

For example gstreamer-vaapi includes explicitly EGL/egl.h
and search for it in its configure.ac.

For example with this patch, if an app includes the headers
  gst/gl/egl/gstglcontext_egl.h
  gst/gl/egl/gstgldisplay_egl.h
  gst/gl/egl/gstglmemoryegl.h
it will *no longer* automatically include EGL/egl.h and GLES2/gl2.h.
Which is good because the app might want to use the gstgl api only
without the need to bother about gl headers.

Also added a test: cd tests/check && make libs/gstglheaders.check

efc015f27d gl: GL_ARRAY_BUFFER is not a part of VAO state
As a result we need to bind it on every draw in order to have the
correct state in the GL state machine.

cfbe7d1399 gtk/gl: don't assert when gdk doesn't provide a GL context
Allows the application to check whether gtkglsink is supported by setting
the element to READY.

cd4a93da3b glsyncmeta: separate out gpu/cpu waits.
CPU waits are more expensive and are only required if the CPU is ever going to
access the data. GPU waits perform inter-context synchronisation and are cheaper
as they don't require CPU intervention.

b25807c382 glshader: port to using GstGLSLStage objects for string management
A GstGLShader is now simply a collection of stages that are
compiled and linked together into a program.  The uniform/attribute
interface has remained the same.

0b271a863e gtkglsink: Fix unsafe handling of buffer life time
We need to keep the active buffer (the one we have retreive a
texture id from) otherwise it's racy and upstream may upload
new content before we have rendered or during later redisplay.

0bc7e9a240 gtk: Fix race between queue_draw and destroy
In GTK dispose can be called before the last ref is reached. This
happens when you close the container window. The dispose will be
explicitly called, and destroyed notify will be fired. This patch
fixes this race by properly tracking the widget state.

In the sink, we now set the widget pointer to NULL, so the widget
will properly get created again if you set your pipeline to NULL
state after the widget was destroy, and set it back to PLAYING.

Otherwise we might be waiting for the lock on the main loop (for

aa37a70efb gtkglwidget: Calculate the viewport size ourselves
Getting the current viewport and modifying it relatively will produce an
interesting feedback loop during widget resizing. Over a few frames we
will gradually move the viewport a bit until it converged again, adding
unnecessary additional borders at the top and left.
