Before, a gstgldisplay was instancied by the gl src in terms of gl chain. And then the next element got it through the first gstglbuffer. Now, this is done though queries. All glelements get their ref on a gstgldisplay in READY state. This rewrite is mainly a first step to be able to share OpenGL context hold by the gstgldisplay using more complex glelements. For example, with a glvideomixer. The associated gstgldisplay of each gl chain of the sink pads will share their OpenGL context.
