Windows: Bump JVM to 6u29

More Robust GLProfile Initialization ; Add NativeWindowFactory Shutdown

More Robust GLProfile Initialization
 - Catch GLException in GLDrawableFactory getWasSharedContextCreated(device) impl.,
   which may fail (See comment on Firefox/Chorme EGL deployed library for Windows).

 - If getWasSharedContextCreated(devide) fails, set respective factory availability to false,
   ie. hasDesktopGLFactory, hasEGLFactory, ..

Add NativeWindowFactory Shutdown
  - Currenly a dummy entry, may evolve. X11Util shutdown is issued by respective GLDrawableFactory

JOGLNewtApplet1Run: Issue GLProfile.shutdown() to adapt to the 'new' plugin lifecycle.

Applet 'restart' (init.start.stop.destroy .. init.start...)
didn't work on Windows browsers (Firefox, Safari, Chrome, ..) w/ JVM 6u26..6u29.

It seems that after destroy we loose the ClassLoader already (plugin2)
hence we need to bind to the native resources again.
Solution is to map the JOGL lifecycle of GLProfile [initSingleton()..shutdown()]
to the Applet's [init..destroy].

Move manual GDI utils to GDIUtil ; Minor cleanup.

RegisteredClassFactory: Reference the factories itself instead of the RegisteredClass.
                        This enables the shutdown hook to clear the factories state,
                        which is required for proper recreation.

GLDrawableFactory: Implementations lifecycle is handled via constructor/destroy()

GLProfile: use dbl checked locking w/ volatile ; Proper shutdown sequence.

Complete commit 2c0a0981f7e1376064abd981c79c65c9d1b57410 ; Missed native impl.

X11Util / GDISurface Robustness

X11Util:
  - shutdown: keep list of displays, if not really closed.
  - Init default display name in initSingleton.

GDISurface: Check ReleaseDC and throw exception if fails

Minor edits.

Adapt to GlueGen commit 7e6cf46ed2e0e9772f79e06437596056efa8c682: JNILibLoaderBase addNativeJarLibs(..)

Fix Bug 522: NEWT requestFocus() causes a crash if !isNativeValid()

Fix 96205926731aeb61a862c87974f611d814937c54 GDIUtil native code.

GLContext fix shutdown(): Clear proc address tables and extension cache (GLContextImpl)

New GLProfile.ShutdownType: SHARED_ONLY / COMPLETE - Enhance/Fix Lifecycle Management

- Leave Platform, .. TempJarCache untouched.

- GLDrawableFactoryImpl*: Leave DynamicLibraryBundle(lib-binding) untouched,
  for NativeLibrary, JNILibLoaderBase (JNI libs), .. consistency.

- SHARED_ONLY: shutdown shared GLDrawableFactoryImpl* resources and NativeWindowFactory

- COMPLETE: additionally shutdown GLContext*
            Clear all cached GL/GLX proc-address and device/context mappings.

- Use new "GLProfile.shutdown(GLProfile.ShutdownType.SHARED_ONLY)" in Applets

- X11GLXDrawableFactory Shutdown: Uncomment close/destroy of shared resources.

- JAWTWindow.destroy(): Close the delegated device.
  In case it's X11 this closes the exclusive opened X11 Display.
