          Implemented support for timer queue close ().

        The rationale for these changes is that when using reactors with
        user defined timer queues the reactor does not delete the timer queue
        when being deleted itself. Without any other cleanup this created the
        possibility (as encountered in TAO/tests/Bug_3837_Regression after
        introduction of the TIME_POLICY changes) of outstanding timer handlers
        in the queue being triggered and attempting to access the reactor after
        the reactor has been destroyed.
        Calling close () for timer queues the reactor does not delete solves
        this potential problem.
