[DNSfirewalls] RPZ2 bug fix

[Vernon Schryver]

Fixes for an RPZ bug in patches for several BIND releases are available
by following the link labeled "Patch files for BIND9"
on http://www.redbarn.org/dns/ratelimits

The bug breaks changing RPZ-IP and RPZ-NSIP triggers in slave zones
after they have been transfered with AXFR instead of IXFR.
Variations of the bug are present in some recent BIND releases.
