Jordan K. Hubbard 63f8d699ac Ugen J.S.Antsilevich's latest, happiest, IP firewall code.
Poul:  Please take this into BETA.  It's non-intrusive, and a rather
substantial improvement over what was there before.

Jordan K. Hubbard ad63b51399 2 11th-hour fixes from Ugen (not Uben, sorry!) J.S.Antsilevich.
I think it's time for Ugen to get a freefall account, just so I can
direct mail at him directly and let him drop off patches for us here.  Ugen?
Done!

Garrett Wollman 5e9ae478ac Shuffle some functions and variables around to make it possible for
multicast routing to be implemented as an LKM.  (There's still a bit of
work to do in this area.)

Garrett Wollman 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.
