* Build with or without INET, INET6, or KVM features.
* When built without KVM, the sysctl-based getifmaddrs() function
is used as the back-end for the utility.
* Reflect the fact that FreeBSD now uses the in_multi refcount as
a true refcount.
* Style.

a less detailed display, equivalent to that of the soon-to-be-retired
netstat -g host-mode output.

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.
