Bug 665: Allow re-association of GLContext/GLEventListener to a GLDrawable (Part 4)

Note:

  - GLEventListenerState preservs the GLAutoDrawable state,
    i.e. GLContext, all GLEventListener and the GLAnimatorControl association.

  - GLEventListenerState may be utilized to move the state from a dying GLAutoDrawable,
    to be moved to a new created GLAutoDrawable at a later time.

  - GLEventListenerState will be made public soon.

+++

Exessive unit tests cover the new feature, tested manually on GNU/Linux/X11 and OSX(Java6/Java7).

+++

- GLAutoDrawable
  - Change 'setContext(..)' to allow the destruction of the unbound old context:
      'setContext(GLContext newCtx)' -> 'setContext(GLContext newCtx, boolean destroyPrevCtx)'

  - Implementations: Properly implement 'setRealized(..)' incl. obeying threading constraints if exists.
    Method is being utilized at least for GLEventListenerState.moveTo(..)
    to unrealize and realize the drawable resources.

Fix propagation of GLContext/GLDrawable association change (Bottom -> Top):

  GLDrawableImpl.associateContext
      GLContextImpl.associateDrawable
          GLContextImpl.makeCurrent
          GLContextImpl.destroy
          GLContext.setGLDrawable
              ...
              GLDrawableHelper.switchContext
                  GLAutoDrawble.setContext

associateDrawable(..)/associateContext(..) unifies and hence:
    - GLContextImpl.contextRealized() (removed)
    - GLDrawableImpl.contextRealized() (removed)
    - GLDrawableImpl.associateContext(..) (merged)
    - MacOSXCGLContext.drawableChangedNotify(..) (removed)

+++

- EGLUpstreamSurfaceHook.evalUpstreamSurface() validates the surface's device for reusage,
  which is valid in case of GLEventListenerState.moveTo(..)

- MacOSXCGLContext.NSOpenGLImpl: pixelFormat replaces NSOpenGLLayerPfmt and has simplified lifecycle [create..destroy],
  while native NSOpenGLLayer code only holds the reference until released.
