Fix buffer overrun.

MFC after: 1 day

- Remove struct ifinfo *iflist. It is no longer used.
- Suppress warnings about increase of alignment requirement.

- Use time_uptime instead of time_second in data structures for
PF_INET6 in kernel. This fixes various malfunction when the wall time
clock is changed. Bump __FreeBSD_version to 1000041.

- Use clock_gettime(CLOCK_MONOTONIC_FAST) in userland utilities.

Silent warnings.

- Add ":origin" label to the interface id for resolvconf(8). (r223149)
- Add -u option to enable adding :[RA-source-address] to the interface id.
(r223149)
- s/INET6_ADDRSTRLEN/sizeof(ntopbuf)/ (r223149)
- Fix a bug that can prevent -D from being overridden by -d. (r223149)
- /-P pidfile/-p pidfile/ for consistency with rtadvd(8). (r223149)
- Fix -F flag handling to support receiving RAs even when ip6.forwarding=1.
(r225150)

Approved by: re (kib)

- Accumulate RA options instead of replacing old ones when a new RA arrived.
RFC 4861 6.3.4 clearly defines handling multiple RAs in this way.

- RDNSS/DNSSL options from multiple RAs on a single link will be
gathered and sent to resolvconf(8).

- Call "resolvconf -d" only after at least one RDNSS or DNSSL option is
received and then all of them are expired.

- The rtsold.dump output now supports displaying a list of the RA options.

- Use more human-readable expression for logging values of struct timeval.

Discussed with: ume

- Disable "resolvconf -d" temporarily to avoid extra invocations of the script
under a certain condition.
- Fix argv handling.

Spotted by: ume

- Implement RDNSS and DNSSL options (RFC 6106, IPv6 Router Advertisement
Options for DNS Configuration) into rtadvd(8) and rtsold(8). DNS
information received by rtsold(8) will go to resolv.conf(5) by
resolvconf(8) script. This is based on work by J.R. Oldroyd (kern/156259)
but revised extensively[1].

- rtadvd(8) now supports "noifprefix" to disable gathering on-link prefixes
from interfaces when no "addr" is specified[2]. An entry in rtadvd.conf
with "noifprefix" + no "addr" generates an RA message with no prefix
information option.

- rtadvd(8) now supports RTM_IFANNOUNCE message to fix crashes when an
interface is added or removed.

- Correct bogus ND_OPT_ROUTE_INFO value to one in RFC 4191.

rtsol(8)/rtsold(8): make WARNS=3 clean

Cleanup of userland __P use

ansify.

Obtained from: KAME

- improved the -a option. it can probe a interface automatically when
the interface wake up. it can be started anytime even when there is
no network interface on the list of intarfaces in the kernel.
- get a correct link ID for each interface at initialization
(using scope libraries if HAVE_SCOPELIB is defined).
- fill in sin6_scope_id correctly before sendmsg().

__FUNCTION__ --> __func__

Explicitly specifies sin6_family & sin6_len of sockaddr_in6 for raw socket
destination.
(Currently lack of their specification does not lead to any problem, because
kernel does not check the consistency between actual address and its
address family / length on raw socket.

However kernel should always check their consistency and stop sending packets
if there is a contradiction. Considering backward compatibility of
programs, I just fixed rtsol now; I'd like to fix the kernel behavior later.)

Sync with recent KAME.
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.
