Better shared GLAutoDrawable synchronization: Block slave instances to also block until all master's GLEventListener.init(..) methods have been called

Better shared GLAutoDrawable synchronization.
Block slave instances to also block until all master's GLEventListener.init(..) methods have been called

- GLSharedContextSetter: Add areAllGLEventListenerInitialized()
  - GLCanvas (SWT, AWT)
  - GLJPanel
  - GLAutoDrawableBase (GLWindow, ..)

- GLDrawableHelper's isSharedGLContextPending(..)
  takes 'areAllGLEventListenerInitialized()' into consideration
  allowing to block the slave creation until master is completed.

This solves teh use case, where the master creates resources in it's
GLEventListener initialization (buffers), which are shared with
it's slaves.
