- Fix GLProcAddressResolver regression: Use GLProcAddressResolver !

- X11GLXDrawableFactory:
    - Move shared resource creation/destruction into it's own thread
    - Remove the ATI hack (no XDisplay closing) for every Display,
      this is only necessary for the shared XDisplay and in case of AWT.

- Newt
    - Display: Only pumpMessages if device is ready.
    - X11Display: Verify handle not null at DispatchMessage.

- Common recursive ToolkitLock implementation, from
    src/nativewindow/classes/com/jogamp/nativewindow/impl/LockingNativeWindowFactory.java and
    src/newt/classes/com/jogamp/newt/Window.java,
    -> com.jogamp.nativewindow.impl.RecursiveToolkitLock

- Unique XLockDisplay/XUnlockDisplay call via X11Util to simplify debugging.
  X11Util: Added debug code for XLockDisplay/XUnlockDisplay.
           Added fast LongObjectHashMap
           Added static lib loading and initialization.
           Removed active and passive list, as well as unused methods,
           to easy maintenance. Possible since the only 'uncloseable' Display
           might be the shareable one.
- X11Lib: Added static initialization via X11Util

Test:
    junit/com/jogamp/test/junit/jogl/demos/gl2/gears/TestGears*
        - Add WindowListener for quit ..
