/** @short  close (or dispose) the given resource.

    @descr  It try to close the given resource first.
            Delegating of the ownership can be influenced from
            outside. If closing isnt possible (because the
            needed interface isnt available) dispose() is tried instead.
            Al possible exception are handled inside.
            So the user of this method has to look for the return value only.

    @attention  The given resource will not be cleared.
                But later using of it can produce an exception!

    @param  xResource
            the object, which should be closed here.

    @param  bDelegateOwnerShip
            used at the XCloseable->close() method to define
            the right owner in case closing failed.

    @return [bool]
            sal_True if closing failed.
