a1f7e5f8ee scope cleanup. with this change
- 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.

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.

abbd890233 o Merge <machine/ansi.h> and <machine/types.h> into a new header
called <machine/_types.h>.
o <machine/ansi.h> will continue to live so it can define MD clock
  macros, which are only MD because of gratuitous differences between
  architectures.
o Change all headers to make use of this.  This mainly involves
  changing:
    #ifdef _BSD_FOO_T_
    typedef	_BSD_FOO_T_	foo_t;
    #undef _BSD_FOO_T_

o Use POSIX spelling for types, where possible.
o Define size_t in the __BSD_VISIBLE case (this isn't really needed
  for standards conformance, but follows the tradition of not
  requiring <sys/types.h> as a prerequisite).
o Use _BYTE_ORDER and friends instead of BYTE_ORDER and friends, since
  there may not be enough pollution in order for the latter to work.
o Add an XXX note about the missing IPPROTO_IPV6 macro.

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.
