Update to 8.13.8.  Changes:

8.13.8/8.13.8   2006/08/09
        Fix a regression in 8.13.7: if shared memory is activated, then
                the server can erroneously report that there is
                insufficient disk space.  Additionally make sure that
                an internal variable is set properly to avoid those
                misleading errors.  Based on patch from Steve Hubert
                of University of Washington.
        Fix a regression in 8.13.7: the PidFile could be removed after
                the process that forks the daemon exited, i.e., if
                sendmail -bd is invoked.  Problem reported by Kan Sasaki
                of Fusion Communications Corp. and Werner Wiethege.
        Avoid opening qf files if QueueSortOrder is "none".  Patch from
                David F. Skoll.
        Avoid a crash when finishing due to referencing a freed variable.
                Problem reported and diagnosed by Moritz Jodeit.
        CONTRIB: cidrexpand now deals with /0 by issuing the entire IPv4
                range (0..255).
        LIBMILTER: The "hostname" argument of the xxfi_connect() callback
                previously was the equivalent of {client_ptr}.  However,
                this did not match the documentation of the function, hence
                it has been changed to {client_name}.  See doc/op/op.*
                about these macros.
