    Make all begindir or one-hop circuits internal
    
    This solves bug 5283, where client traffic could get sent over the
    same circuit as an anonymized connection to a directory, even if
    that circuit used an exit node unsuitable for clients.  By marking
    the directory connection as needs_internal, we ensure that the
    (non-internal!) client-traffic connection won't be sent over the
    same circuit.
