Proper X11 Display Closing

X11Util:
Removed TLS semantics, since TLS name -> dpy mapping is erroneous at this point.
Added lists for open connections (for optional later shutdown).

AbstractGraphicsDevice interface and implementations:
Adding 'close()' method allowing native implementations the ability
to close the native resource, ie X11GraphicsDevice.
This becomes necessary for 'on the fly' created X11 Display connections,
ie in X11AWTGLXGraphicsConfigurationFactory, which enables closing.
Utilize 'close' call in use cases: GLCanvas, GLJPanel and AWTCanvas.

Remove active X11 Display creation in X11JAWTWindow,
as a last resort, use the X11SunJDKReflection method.
Used for reference only, not active rendering etc,
mostly for on the fly AWT parenting in NewtFactoryAWT.

However, these 'on the fly' references are erroneous and should be remodelled,
ie passice and active X11GraphicsDevice's ..
