de8db47547 Add support for RFC 3542 Adv. Socket API for IPv6 (which obsoletes 2292).
* RFC 3542 isn't binary compatible with RFC 2292.
* RFC 2292 support is on by default but can be disabled.
* update ping6, telnet and traceroute6 to the new API.

From the KAME project (www.kame.net).

78678b130a Better support of IPv6 scoped addresses.
- most of the kernel code will not care about the actual encoding of
  scope zone IDs and won't touch "s6_addr16[1]" directly.
- similarly, most of the kernel code will not care about link-local
  scoped addresses as a special case.
- scope boundary check will be stricter.  For example, the current
  *BSD code allows a packet with src=::1 and dst=(some global IPv6
  address) to be sent outside of the node, if the application do:
    s = socket(AF_INET6);
    bind(s, "::1");
    sendto(s, some_global_IPv6_addr);
  This is clearly wrong, since ::1 is only meaningful within a single
  node, but the current implementation of the *BSD kernel cannot
  reject this attempt.
- and, while there, don't try to remove the ff02::/32 interface route
  entry in in6_ifdetach() as it's already gone.

This also includes some level of support for the standard source
address selection algorithm defined in RFC3484, which will be
completed on in the future.

c24781af04 Pass the current process structure to in_pcbconnect() so that it can
pass it to in_pcbbind() so that can allocate a low numbered port
if setsockopt() has been used to set IP_PORTRANGE to IP_PORTRANGE_LOW.
While there, fail in_pcbconnect() if the in_pcbbind() fails - rather
than sending the request out from a port of zero.
This has been largely broken since the socket option was added in 1998.

f7abb16323 Fix per-PCB IPsec policy cache for FAST_IPSEC:
The sys/netipsec policy-cache (added by Jason Thorpe as a rewrite of
the KAME per-PCB policy cache) assumes that policy-cacheable PCBs
always has a non-NULL inph_sp in the common PCB header.  So we must
do all the per-PCB policy cache calls when either (KAME) IPSEC, or
FAST_IPSEC is defined.  ``Make it so''.

We can now support non-IPsec'ed IPv6 traffic, when both
``options FAST_IPSEC'' and ``options INET6'' are configured.

- do not bark when we forward packet to loopback.

4308599c5a disallow bind(2) with IPv4 mapped address for now. port number check is
insufficient at this moment and we can bind(2) two sockets listen on same
port number.

for real fix, we need to check inpcb table with in6pcb.  we can't
find inpcb chain from particular in6pcb chain (like finding tcbtable from tcb6)
luckily RFC2553 does not talk about bind(2) behavior for IPv4 mapped.
IPv4 mapped brings in too much complexities...
