Also re-do the method we use for disconnecting ourselves from the supplied
gmp and z libraries so that this can be maintained in the future (sigh!).
patch-ac: call setsid() before setlogin() in the child (when emulating rsh)
otherwise the setlogin() will fail when/if the proposed setlogin() changes
