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
