GLAutoDrawable* refinement of abstraction / generalization - API Change!

- GLAutoDrawable (compat change - recompile):
  - 'void invoke(boolean wait, GLRunnable glRunnable)' -> 'boolean invoke(boolean wait, GLRunnable glRunnable)'
    Allows notifying caller whether the task has been executed or at least enqueued.

- GLAutoDrawable add 'GLEventListener removeGLEventListener(int index)'
  - This allow one to remove a specific GLEventListener and reusing it (return value).

- GLDrawableImpl remove 'destroy()' to favor 'setRealized(false)'
  - Using more common code of GLAutoDrawableBase, i.e. GLPbufferImpl can use defaultDestroyOp().
  - Removes redundancy of methods

- GLAutoDrawableBase/Delegate
  - better 'default' names to emphasize it's purpose, adding API doc

  - includes more generic functionality
    - defaultWindowDestroyNotify()
    - defaultDestroyOp()

  - TestGLAutoDrawableDelegateNEWT demonstrates a simple example w/ all window events handled.

- Fix TestParenting01cSwingAWT's threading use (gl disturbance thread)
