remotely, but they would be if e.g. it happened to call the logging
function using a DNS hostname.
Also replace random() by arc4random() - only one of these is arguably
required since it's directly used in the protocol, but we might as
well replace both to avoid using two different PRNGs.

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.
endian-ness fix, Router Alert options on IGMP messages, and a
new keyword, "advert_metric", for fine-tuning tunnel metrics.
This also includes a new mtrace, which is also unreleased but
builds significantly on the experiences of users' troubles with
using and understanding mtrace in release 3.8 .
(unreleased does not, of course, mean untested!)
This is a candidate for both 2.2 and 2.1.6 .
This will make FreeBSD boxes better behaved 'MBONE Citizens', based on
a couple of the comments about the severity of fixes..

mrouted-3.5n. This is being splatted onto the head rather than properly
imported thanks to the ``delete trailing whitespace'' screw. This code is
now actively working in an operational environment (the DARTNET) so I
have some confidence that the basic functionality actually works.

the fixes!):
o Scoped addresses might let traffic in
o IGMP queries sent with wrong timeouts
o Possible core dump in mtrace if we get a request for which we have no route
o If a member on a transit network left a group, mrouted would stop forwarding
even if there was a downstream router
o Various code cleanups and logging changes

The routine rip_ip_input in raw_ip.c is suggested by Mark Tinguely
(tinguely@plains.nodak.edu). I have been running mrouted with these patches
for over a week and nothing has seemed seriously wrong. It is being run in
two places on our network as a tunnel on one and a subnet querier on the
other. The only problem I have run into is that mrouted on the tunnel must
start up last or the pruning isn't done correctly and multicast packets
flood your subnets.
