279c2b07b4 glcompositionoverlay: Add class for managing GstVideoOverlayCompositionOverlay buffers
Add a class to store and manage the OpenGL texture,
vertex buffer and GstVideoOverlayRectangle.
Transforms overlay coordinate space to vertex buffer space with aspect ratios in mind.

= Example Pipelines =

Simple pipeline

gst-launch-1.0 videotestsrc ! \
  textoverlay text="Hello World" font-desc="sans bold 30" ! \
  glimagesink

Display 3 static overlays at different positions

gst-launch-1.0 videotestsrc ! \
  textoverlay text="text1" valignment="top" font-desc="sans bold 30" ! \
  textoverlay text="text2" halignment="right" font-desc="sans bold 30" ! \
  textoverlay text="text3" halignment="left" font-desc="sans bold 30" ! \
  glimagesink

Display subtitle file over testsrc

66407b9877 glcontext: fix get_current_gl_api on x11/nvidia drivers
They require to get_proc_address some functions through the
platform specific {glX,egl}GetProcAddress rather than the default
GL library symbol lookup.

3343e2dccd glcontext/glx: try creating a context with the highest version
nvidia drivers return the exact version in glGstString (GL_VERSION)
we request on creation so start with the highest known version and

78957c45c2 glcontext: track sharedness with a cookie
The previous approach of traversing the other_context weak ref tree was
1. Less performant
2. Incorrect for context destruction removing a link in the tree

Example of 2:
c1 = context_create (NULL)
c2 = context_create (c1)
c3 = context_create (c2)
context_can_share (c1, c3) == TRUE
context_destroy (c2)
unref (c2)
context_can_share (c1, c3) returns FALSE when it should be TRUE!

This does not remove the restriction that context sharedness can only
be tracked between GstGLContext's.

5f38bcf905 uploadelement: Protect against NULL pointer
I notice that if you stop the pipeline during a renegotiation
the upload may be NULL while an allocation query is being run.
In that scenario, returning FALSE to the allocation query is the
best thing.

This will deadlock if the main thread is the one who creates the GstGLContext.
