    These changes add locking. There are two locks: one for static rules and
    one for dynamic rules. The associated dummynet changes are not included as
    I haven't tested them yet. The locking scheme may need to be revised to
    use something like sx locks; this will be revisited in a later pass.

    I've been running with these changes for a week on my interior firewall,
    but they are very lightly tested and need a good review and more testing.
    I don't plan to commit them until they get more of each.
