f824b5187e Widen struct sockbuf's sb_timeo member to int from short. With 
non-default but reasonable values of hz this member overflowed,
breaking NFS over UDP.

Also, as long as I'm plowing up struct sockbuf ... Change certain
members from u_long/long to u_int/int in order to reduce wasted
space on 64-bit machines.  This change was requested by Andrew
Gallatin.

Netstat and systat need to be rebuilt.  I am incrementing
__FreeBSD_version in case any ports need to change.

bd7142087b - Make ip_rtaddr() global, and use it to look up the correct source 
address in icmp_reflect().
- Two new "struct icmpstat" members: icps_badaddr and icps_noroute.

3384154590 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.

convert icmp_stats() to use sysctl(3) to retrieve the information
rather than kvm.  This makes it easy to also print whether ICMP address
mask responses are enabled, so do so.

e1fb4daa3e TCP statistics are unsigned counters. 
Tor Egge reports counter wrap and requests and update to quad_t sized
counters, which is also a good thing to do,  but I'm unhappy about adding
two more instructions into the  code path every time we doink a counter.

Maybe with or after the Lite2 merge...
