Log message:
Make IP multicast router global variable MP safe.

Use a multicast router rwlock to protect the mrt_mrouter array.
Since we support one router per route table, also implement an API
version per router.  Sockets in mrt_mrouter are reference counted.
Fix the name space a bit by using mrt_ prefix consistently.  Keep
existing netlock and kernel lock until fine grained locking has
been finished.
