I think it is okay for dnParent (and dn_parent) to assume that the
DN is pretty (dnPretty) or is normalized (dnNormalize), which
should allow for a very efficient implementation, e.g.:
        parent = strchr(in,','));

I note that as soon as dn_parent() is not used in any of the
primary backends, it should be removed from the frontend.
Likewise for dn_normalize().  dn_validate() is already history.
