    router: Authorities add their own IPv6 to trusted dir servers
    
    Authorities currently add themselves to the trusted dir servers list,
    but if they have an IPv6 ORPort, they leave it out.
    
    This commit makes authorities add their own IPv6 ORPort to the trusted
    dir servers list.
    
    Closes ticket 32822.
