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

gst-launch-1.0 videotestsrc ! \
  textoverlay name=foo filesrc location=foo.srt ! subparse ! queue ! foo. foo. ! \
  glimagesink

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
work our way down.

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.

cff2d74cd4 gl/eagl: Don't call anything synchronously from the main thread 
This will deadlock if the main thread is the one who creates the GstGLContext.
All things we call from the main thread should be possible from any thread.
