Fix X11 Display Connection leak w/ new GLAutoDrawableBase code when used w/ offscreen drawables, reported by Mark Raynsford

New common GLAutoDrawableBase missed to close the AbstractGraphicsDevice
in case it has been created and dedicated for the passed GLDrawable.
This detailed knowledge is only known to the creator, hence it is passed
in the constructor and is being passed through all specializations.

Further more the new X11/GLX impl. of GLDrawableFactory's
'createMutableSurfaceImpl' always creates it's own private X11 display connection
to avoid locking / threading issues. Since the old implementation reused the
shared display connection which is prone to threading issues, this bug was not visible before.

Also fixed the unit test TestNEWTCloseX11DisplayBug565,
now correctly validating that no display connection is left over
after a new cycle of create/destroy of onscreen and offscreen drawables.
