Is this for handling CI rename properly?  Barry was looking into this,
but i told him to hold off for a while - the lookup code is changing
quite a bit because Al is trying to sort out the lookup intent mess and
we hopefully will stop passing the nameidata to ->lookup soon.

Also I think LOOKUP_RENAME_TARGET might be a little more descriptive
than LOOKUP_RENAME_NEW.
