OS X Layered View Part8: Generalize OffscreenLayerSurface ; Use local JAWT instance ; Applet's on OS X are working

Generalize OffscreenLayerSurface
  - Using new OffscreenLayerSurface allows using this functionality in a clean manner,
    ie. no 'dirty' usage of MacOSXJAWTWindow in a JOGL GL class.

  - 'Promoting' OffscreenLayerSurface functionality to JAWTWindow
    and it's handling to GLDrawableFactoryImpl::createGLDrawable().

  - Move MacOSXCGLDrawableFactory's "MacOSXJAWTWindow getLayeredSurfaceHost(NativeSurface surface)"
    to NativeWindowFactory "OffscreenLayerSurface getOffscreenLayerSurface(NativeSurface surface, boolean ifEnabled)"

Use local JAWT instance
  - Only w/ a local JAWT instance per JAWTWindow it is possible to switch between
    offscreen-layer and onscreen. We also have to determing offscreen-layer lazy
    at surface lock, since only at that time we have knowledge whether it's an Applet
    or not.

+++

ContextUpdater:
  Use local pthread mutex, add DEBUG output

JAWTWindow/NewtCanvasAWT:
  Adding methods to request offscreen-layer-surface (if supported),
  besides 'if applet' this may trigger the new functionality.

Applet's on OS X are working:
  - OS X 10.6.4
    - Safari:
      - Hangs for a while at start .. whole screen freezes .. approx. 10s
      - Sometimes crashes when Applet stops - after all our resources are released!
      - Keyboard input isn't assigned sometimes.
      - Otherwise .. works well, incl. offscreen/onscreen parenting

    - Firefox 8.0:
      - Hangs for a while at start .. whole screen freezes .. approx. 10s
      - Sometimes crashes when Applet stops - after all our resources are released!
      - Keyboard input is never assigned.
      - Otherwise .. works well, incl. offscreen/onscreen parenting

  - OS X 10.7
    - Safari:
      - Sometimes crashes when Applet stops - after all our resources are released!
      - Keyboard input isn't assigned sometimes.
      - Otherwise .. works well, incl. offscreen/onscreen parenting
