I have improved upon my original OpenBSD carp(4) logging patch by merging the 
FreeBSD patch into NetBSD 4.

>How-To-Repeat:
Use carp(4) -- find the default logging/debugging drastically insufficient.
>Fix:
Apply patch at URL above.

There is some confusion about the CARP_LOG macro so some messages have a 
duplicate interface name printed right now.
