Removing some of the bro-aux tools?

Craig noted that some of tools currently in bro-aux are actually
maintained independently (and we're shipping old versions right now).

It seems to make sense to remove these from bro-aux. We could instead
just list them with URLs in the README and/or on the web site.

Specifically, this would mean removing:

    cf (distribution at
    hf (distribution at

Plus, Craig just created a replacement for the SSL scripts in
bro-aux/scripts/ca-*, with the new one availabe at

All these also have (or will have soon) their own FreeBSD ports.

Any objections to removing?
