This work was based on kame-20010528-freebsd43-snap.tgz and some
critical problem after the snap was out were fixed.
There are many many changes since last KAME merge.
TODO:
- The definitions of SADB_* in sys/net/pfkeyv2.h are still different
from RFC2407/IANA assignment because of binary compatibility
issue. It should be fixed under 5-CURRENT.
- ip6po_m member of struct ip6_pktopts is no longer used. But, it
is still there because of binary compatibility issue. It should
be removed under 5-CURRENT.

It may happen (if the routing table is screwed) that the gateway
route is the same route as the one being modified, in which case
a kernel reports EDQUOT. Be more verbose about this:

- Use inet_ntoa(3) where it should have been used. This
part of code simply wasn't converted to the "new" style
after the routename() function was converted from the
protocol-generic version to protocol-specific version

the `gateway' as network address and passed its name to getnetbyname(3),
which in the BIND resolution case does the T_PTR lookup on that name.

Without this fix, routes with IPv6 scoped addr won't work when it is
assigned by "route" command.

IPv6 scoped addr display is not yet supported by ifconfig
and route. Now almost of IPv6 apps support it, so its support
in ifconfig and route is important to keep consisetncy, and
to avoid user confusion.

Opening the socket is the only privileged operation route requires.
Make a couple of static buffers bigger, and use strncpy() and snprintf() where

This patch allows true interface routing to be controlled
from the command line..
you can now do:
route add default -interface ppp0
even if you have no clue what the address at the other end is..
this is part of a set of changes that allow true "unnumbered links"
such as netcom run between their sites..
In practice you should assign the address from one of your ethernet
interfaces to the local side of the P2P link so that IP doesn't
say that the packet comes from 255.255.255.255, but
there is no need whatsoever to assign an address of any kind
to the remote end of the link.. useful for frame relay links etc also.
