thorpej 41d4822677 Resolve conflicts from merge of 3.2a7, take 2. Also, eliminate some 
silly differences between the NetBSD copy of the code and the
vendor branch, keeping only those which are necessary.  Of those
differences that currently exist, several "portability to NetBSD"
issues, which will be fed back to the ipfilter author.
