itojun 23a03329ef verify ICMPv6 too big messages based on TCP pcbs, and/or IPsec SA.
TODO: udp6, and sendto consideration.  as pmtud is mandatory for IPv6,
it is rather important for us to support those cases.
TODO: more testing

thorpej ea9b5a9106 Restructure the Path MTU Discovery code somewhat to avoid
entering rtentry's for hosts we're not actually communicating
with.

Do this by invoking the ctlinput for the protocol, which is
responsible for validating the ICMP message:
	* TCP -- Lookup the connection based on the address/port
	  pairs in the ICMP message.
	* AH/ESP -- Lookup the SA based on the SPI in the ICMP message.

If validation succeeds, ctlinput is responsible for calling
icmp_mtudisc().  icmp_mtudisc() then invokes callbacks registered
by protocols (such as TCP) which want to take some sort of special
action when a path's MTU changes.  For TCP, this is where we now
refresh cached routes and re-enter slow-start.

As a side-effect, this fixes the problem where TCP would not be
notified when a path's MTU changed if AH/ESP were being used.

XXX Note, this is only a fix for the IPv4 case.  For the IPv6
XXX case, we need to wait for the KAME folks.

itojun 1a2a1e2b1f bring in latest KAME ipsec tree.
- interop issues in ipcomp is fixed
- padding type (after ESP) is configurable
- key database memory management (need more fixes)
- policy specification is revisited

XXX m->m_pkthdr.rcvif is still overloaded - hope to fix it soon

- loosen ipsec restriction on packet diredtion.
- revise icmp6 redirect handling on IsRouter bit.
- tcp/udp notification processing (link-local address case)
- cosmetic fixes (better code share across *BSD).
