struct kif is internal to the kroute code with the exception of the
'depend on' tracking message. So create an extra object for this message
and move struct kif to kroute.c.
I renamed the IMSG just to make it clear what this is about and to make
sure I did not miss something.
After that struct kif_node will follow struct kroute_node.
