[606/906] determine the GL platform to use at runtime

Browse source 
- Make GstGLWindow subclassablerather than specified at compile time.
- Add GstGLWindowX11 for x11 windows and two subclasses, GstGLWindowX11GLX
  and GstGLWindwX11EGL for GLX and EGL repectively. (win32 and cocoa
  ports to come)
- Also cleanup GL library detection in configure.ac
