6c572040c6 Eliminate use of M_EXT in IP6_EXTHDR_CHECK() by trimming a redundant
'if'/'else' case: it matches the simple 'else' case that follows.

This reduces awareness of external-storage mechanics outside of the
mbuf allocator.

1263305f0c Start removing IPv6 Type 0 Routing header code.
RH0 was deprecated by RFC 5095.

While most of the code had been disabled by #if 0 already, leave a
bit of infrastructure for possible RH2 code and a log message under
BURN_BRIDGES in case a user still tries to send RH0 packets.

4b79449e2f Rather than using hidden includes (with cicular dependencies),
directly include only the header files needed. This reduces the
unneeded spamming of various headers into lots of files.

For now, this leaves us with very few modules including vnet.h
and thus needing to depend on opt_route.h.

8b615593fc Step 1.5 of importing the network stack virtualization infrastructure
from the vimage project, as per plan established at devsummit 08/08:
http://wiki.freebsd.org/Image/Notes200808DevSummit

Introduce INIT_VNET_*() initializer macros, VNET_FOREACH() iterator
macros, and CURVNET_SET() context setting macros, all currently
resolving to NOPs.

Prepare for virtualization of selected SYSCTL objects by introducing a
family of SYSCTL_V_*() macros, currently resolving to their global
counterparts, i.e. SYSCTL_V_INT() == SYSCTL_INT().

Move selected #defines from sys/sys/vimage.h to newly introduced header
files specific to virtualized subsystems (sys/net/vnet.h,
sys/netinet/vinet.h etc.).

All the changes are verified to have zero functional impact at this
point in time by doing MD5 comparision between pre- and post-change
object files(*).

(*) netipsec/keysock.c did not validate depending on compile time options.

603724d3ab Commit step 1 of the vimage project, (network stack)
virtualization work done by Marko Zec (zec@).

This is the first in a series of commits over the course
of the next few weeks.

Mark all uses of global variables to be virtualized
with a V_ prefix.
Use macros to map them back to their global names for
now, so this is a NOP change only.

We hope to have caught at least 85-90% of what is needed
so we do not invalidate a lot of outstanding patches again.

f95d46333d Switch Advanced Sockets API for IPv6 from RFC2292 to RFC3542
(aka RFC2292bis).  Though I believe this commit doesn't break
backward compatibility againt existing binaries, it breaks
backward compatibility of API.
Now, the applications which use Advanced Sockets API such as
telnet, ping6, mld6query and traceroute6 use RFC3542 API.

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.

1aa540eb03 Forbid include of soem inet6 header files from wrong place
KAME put INET6 related stuff into sys/netinet6 dir, but IPv6
  standard API(RFC2553) require following files to be under sys/netinet.
    netinet/ip6.h
    netinet/icmp6.h
  Now those header files just include each following files.
    netinet6/ip6.h
    netinet6/icmp6.h

  Also KAME has netinet6/in6.h for easy INET6 common defs
  sharing between different BSDs, but RFC2553 requires only
  netinet/in.h should be included from userland.
  So netinet/in.h also includes netinet6/in6.h inside.

  To keep apps portability, apps should not directly include
  above files from netinet6 dir.
  Ideally, all contents of,
    netinet6/ip6.h
    netinet6/icmp6.h
    netinet6/in6.h
  should be moved into
    netinet/ip6.h
    netinet/icmp6.h
    netinet/in.h
  but to avoid big changes in this stage, add some hack, that
    -Put some special macro define into those files under neitnet
    -Let files under netinet6 cause error if it is included
     from some apps, and, if the specifal macro define is not
     defined.
     (which should have been defined if files under netinet is
     included)
    -And let them print an error message which tells the
     correct name of the include file to be included.

  Also fix apps which includes invalid header files.
