b1e4abd246 Give struct socket structures a ref counting interface similar to
vnodes.  This will hopefully serve as a base from which we can
expand the MP code.  We currently do not attempt to obtain any
mutex or SX locks, but the door is open to add them when we nail
down exactly how that part of it is going to work.

ce17880650 o Replace reference to 'struct proc' with 'struct thread' in 'struct
sysctl_req', which describes in-progress sysctl requests.  This permits
  sysctl handlers to have access to the current thread, permitting work
  on implementing td->td_ucred, migration of suser() to using struct
  thread to derive the appropriate ucred, and allowing struct thread to be
  passed down to other code, such as network code where td is not currently
  available (and curproc is used).

o Note: netncp and netsmb are not updated to reflect this change, as they
  are not currently KSE-adapted.

e9d3164d29 Fixed the behavior when there is no inbound policy for the ipsec
tunneled packet.
When there is no suitable inbound policy for the packet of the ipsec
tunnel mode, the kernel never decapsulate the tunneled packet
as the ipsec tunnel mode even when the system wide policy is "none".
Then the kernel leaves the generic tunnel module to process this
packet.  If there is no rule of the generic tunnel, the packet
is rejected and the statistics will be counted up.

8071913df2 Pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2.
Have sys/net/route.c:rtrequest1(), which takes ``rt_addrinfo *''
as the argument.  Pass rt_addrinfo all the way down to rtrequest1
and ifa->ifa_rtrequest.  3rd argument of ifa->ifa_rtrequest is now
``rt_addrinfo *'' instead of ``sockaddr *'' (almost noone is
using it anyways).

Benefit: the following command now works.  Previously we needed
two route(8) invocations, "add" then "change".
# route add -inet6 default ::1 -ifp gif0

Remove unsafe typecast in rtrequest(), from ``rtentry *'' to
``sockaddr *''.  It was introduced by 4.3BSD-Reno and never
corrected.

make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

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.
