- Reduce unnecessary loop in pmsg_addrs().
- Remove iso_ntoa(). This is not used.
- Fix a bug in sodump() which prevented struct sockaddr_in6 from displaying.
- Fix a bug in in fiboptlist_csv() which could cause free() of uninitialized
pointer.
- Style cleanups:
. Add missing "static" keywords.
. Use an array of struct sockaddr_storage instead of sockunion for rtmsg.
. Use err() and errx() instead of pair of fprintf(stderr, "...") + exit(1).
. Use nitems() macro.
. Various style(9) fixes.
Since ARP and routing are separated, "proxy only" entries
don't have any meaning, thus we don't need additional field
in sockaddr to pass SIN_PROXY flag.
New kernel is binary compatible with old tools, since sizes
of sockaddr_inarp and sockaddr_in match, and sa_family are
filled with same value.
The structure declaration is left for compatibility with
third party software, but in tree code no longer use it.

KAME-specific sin6_scope_id handling routine from each userland utility:
sin6.sin6_scope_id = ntohs(*(u_int16_t *)&sin6.sin6_addr.s6_addr[2]);
This behavior can be controlled by net.inet6.ip6.deembed_scopeid. This is
set to 1 by default (sin6_scope_id will be filled in the kernel).

if a entry is not route add -net xxx/bits then we should use
the addr (xxx) to establish the number of bits by looking at
the first non-zero bit. So if we enter
route add -net 10.1.1.0 10.1.3.5
this is the same as doing
route add -net 10.1.1.0/24
Since the 8th bit (zero counting) is set to 1 we set bits
to 32-8.
Users can of course still use the /x to change this behavior
or in cases where the network is in the trailing part
of the address, a "netmask" argument can be supplied to
override what is established from the interpretation of the
address itself. e.g:
route add -net 10.1.1.8 -netmask 0xff00ffff
should overide and place the proper CIDR mask in place.

1. separating L2 tables (ARP, NDP) from the L3 routing tables
2. removing as much locking dependencies among these layers as
possible to allow for some parallelism in the search operations
3. simplify the logic in the routing code,
The most notable end result is the obsolescent of the route
cloning (RTF_CLONING) concept, which translated into code reduction
in both IPv4 ARP and IPv6 NDP related modules, and size reduction in
struct rtentry{}. The change in design obsoletes the semantics of
RTF_CLONING, RTF_WASCLONE and RTF_LLINFO routing flags. The userland
applications such as "arp" and "ndp" have been modified to reflect
those changes. The output from "netstat -r" shows only the routing
entries.
Quite a few developers have contributed to this project in the
past: Glebius Smirnoff, Luigi Rizzo, Alessandro Cerri, and
Andre Oppermann. And most recently:
- Kip Macy revised the locking code completely, thus completing
the last piece of the puzzle, Kip has also been conducting
active functional testing
- Sam Leffler has helped me improving/refactoring the code, and
provided valuable reviews
- Julian Elischer setup the perforce tree for me and has helped
me maintaining that branch before the svn conversion
'get'. Since rtmsg() always gets called and returns 0 on success and -1
on failure, it's possible to exit with a suitable exit code by calling
exit(ret != 0) instead, as is done at the end of newroute().

command would add incorrect routing entries if network numbers weren't
fully "spelled" out according to their class. For example:
# route add 128.0/16 (works)
# route add 128/16 (doesn't work)
# route add 193.0.0/24 (works)
# route add 193/24 (doesn't work)
Also, rework the way a netmask is deduced from network number if
