JOGL GL4 preperation:

  - Re-Enable GL3bc native library build, works ..
  - Adding all the is/get GL4/GL4bc stubs ..
  - Adding dummy interface GL4 and GL4bc, will be removed when done

  - Context creation refactoring:
    - Move Version information to GLContext
    - Determine version by creation if possible (ARB_create_context),
      only use the unreliable GL_VERSION string if necessary.
    - Offering an almost platform independent ARB_create_context path:
        - createContextARBImpl - platform dependent GLX calls
        - createContextARB     - platform independent setup and version loop
