Change the way we automatically add prefix routes when adding a new address.
This makes it possible to have more than one address with the same prefix.
The first address added is used for the route. On deletion of an address
with IFA_ROUTE set, we try to find a "fallback" address and hand over the
route if possible.
I plan to MFC this in 4 weeks, hence I keep the - now obsolete - argument to
in_ifscrub as it must be considered KAPI as it is not static in in.c. I will
clean this after the MFC.
