0ec4b12334 Introduce support for Mandatory Access Control and extensible
kernel access control.

When generating an IGMP message, invoke a MAC entry point to permit
the MAC framework to label its mbuf appropriately for the target
interface.

c73d99b567 Add netstat(1) knob to reset net.inet.{ip|icmp|tcp|udp|igmp}.stats.
For example, ``netstat -s -p ip -z'' will show and reset IP stats.

If timer calculation results in degenerate value (0), force it to 1
    to avoid divide-by-zero panic later on in calls to IGMP_RANDOM_DELAY().
    I considered simply adding 1 to the timer calculation, but was unsure
    if the calculation was part of the IGMP standard or not so did not want
    to mess with it for all cases.

Distribute all but the most fundamental malloc types.  This time I also
remembered the trick to making things static:  Put "static" in front of
them.

1130b656e5 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

765b90447e These diffs modify the behaviour of multicast clients to conform with the
IGMPv2 spec.  This fixes the following bugs:

o ntohs() on a char provides silly results
o timer needs to be scaled to units of PR_FASTHZ; this was being done
  inconsistenly so now it gets done when it is initialized.

f0068c4a70 Initial get-the-easy-case-working upgrade of the multicast code
to something more recent than the ancient 1.2 release contained in
4.4.  This code has the following advantages as compared to
previous versions (culled from the README file for the SunOS release):

- True multicast delivery
- Configurable rate-limiting of forwarded multicast traffic on each
  physical interface or tunnel, using a token-bucket limiter.
- Simplistic classification of packets for prioritized dropping.
- Administrative scoping of multicast address ranges.
- Faster detection of hosts leaving groups.
- Support for multicast traceroute (code not yet available).
- Support for RSVP, the Resource Reservation Protocol.

What still needs to be done:

- The multicast forwarder needs testing.
- The multicast routing daemon needs to be ported.
- Network interface drivers need to have the `#ifdef MULTICAST' goop ripped
  out of them.
- The IGMP code should probably be bogon-tested.

Some notes about the porting process:

In some cases, the Berkeley people decided to incorporate functionality from
later releases of the multicast code, but then had to do things differently.
As a result, if you look at Deering's patches, and then look at
our code, it is not always obvious whether the patch even applies.  Let
the reader beware.

I ran ip_mroute.c through several passes of `unifdef' to get rid of
useless grot, and to permanently enable the RSVP support, which we will
include as standard.
