29dc7bc636 Merge final round of MLD changes from p4:
ip6_input.c, in6.h:
 * Add netinet6-specific mbuf flag M_RTALERT_MLD, shadowing M_PROTO6.
  * Always set this flag if HBH Router Alert option is present for MLD,
    even when not forwarding.

 icmp6.c:
 * In icmp6_input(), spell m->m_pkthdr.rcvif as ifp to be consistent.
 * Use scope ID for verifying input. Do not apply SSM filters here, no inpcb.
  * Check for M_RTALERT_MLD when validating MLD traffic, as we can't see
    IPv6 hop options outside of ip6_input().

 in6_mcast.c:
 * Use KAME scope/zone ID in in6_multi.
   * Update net.inet6.ip6.mcast.filters implementation to use scope IDs
     for comparisons.
 * Fix scope ID treatment in multicast socket option processing.
   Scope IDs passed in from userland will be ignored as other less
   ambiguous APIs exist for specifying the link.
 * Tighten userland input checks in IPv6 SSM delta and full-state ops.
   * Source filter embedded scope IDs need to be revisited, for now
     just clear them and ignore them on input.
 * Adapt KAME behaviour of looking up the scope ID in the default zone
   for multicast leaves, when the interface is ambiguous.

 mld6.c:
 * Tighten origin checks on MLD traffic as per RFC3810 Section 6.2:
  * ip6_src MAY be the unspecified address for MLDv1 reports.
  * ip6_src MAY have link-local address scope for MLDv1 reports,
    MLDv1 queries, and MLDv2 queries.
  * Perform address field validation *before* accepting queries.
 * Use KAME scope/zone ID in query/report processing.
   * Break const correctness for mld_v1_input_report(), mld_v1_input_query()
     as we temporarily modify the input mbuf chain.
   * Clear the scope ID before handoff to userland MLD daemon.
 * Fix MLDv1 old querier present timer processing.
   With the protocol defaults, hosts should revert to MLDv2 after 260s.
 * Add net.inet6.mld.v1enable sysctl, default to on.

 ifmcstat.c:
 * Use sysctl by default; -K requests kvm(3) if so compiled.

 mld.4:
 * Connect man page to build.

Tested using PCS.

d10910e6ce Merge IGMPv3 and Source-Specific Multicast (SSM) to the FreeBSD
IPv4 stack.

Diffs are minimized against p4.
PCS has been used for some protocol verification, more widespread
testing of recorded sources in Group-and-Source queries is needed.
sizeof(struct igmpstat) has changed.

__FreeBSD_version is bumped to 800070.

d508ff40b9 Improve ifmcstat(8) and fix a few bugs while we're at it:
* Retire the old 'ifmcstat <kernel>' usage.
 * Print AF_LINK records even if run against KVM.
   This makes the KVM backend consistent with the sysctl backend.
 * Suppress printing of link-layer group records by default.
 * Add a -v switch to allow link-layer groups to be printed.
 * If compiled without INET6 support, actually work.
 * If compiled with INET6 support, print the scope ID of
   all IPv6 addresses in both backends.
 * Update man page.
 * Update copyrights.

With this change, it is now reasonable to retire netstat -g.
Most of the SSM related gunk in this file will require later refactoring.

60dd8da775 Considerably rework the ifmcstat utility.
* Build with or without INET, INET6, or KVM features.
  * When built without KVM, the sysctl-based getifmaddrs() function
    is used as the back-end for the utility.
 * Reflect the fact that FreeBSD now uses the in_multi refcount as
   a true refcount.
 * Style.

The utility may now be run without super-user privilege, albeit with
a less detailed display, equivalent to that of the soon-to-be-retired
netstat -g host-mode output.

Possibly merge or split with netstat -g.

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.
