Fix Bug 642 TestJSplitPaneMixHwLw01AWT (AWT-GLCanvas); Robustness GLContext/GLDrawable

- Fix Bug 642 TestJSplitPaneMixHwLw01AWT
  On Windows platform when mixing hw/lw JSplitPanel,
  the GLCanvas is removed and added when splitter is moved.
  The lack of robustness (see below) lead to an exception.

  Note: Only w/ GLJPanel (no hw/lw mixing) the splitter can be moved
  in both direction. Only here it is guaranteed that the GL component
  will survive the action.

- Fix AWT-GLCanvas EDT Runnable: swapBuffer().. / display(..)
  - Check drawable.isRealized() within the lock on the performing thread.
    This is not possible before issuing the EDT Runnable action
    since we cannot hold the lock beforehand.

- Robustness GLDrawableImpl
  - boolean realized -> volatile boolean realized
  - remove 'synchronized' on isRealized() and setRealized(..)
  - Use dbl-checked locking on 'realized' test for swapBuffers() and setRealized(..)

- Robustness GLContextImpl
  - Catch createImpl(..) exception and properly return CONTEXT_NOT_CURRENT
