HardenedBSD/contrib/bind/bin/named/ns_parser.c
Peter Wemm 6b6ac9438f Import bind v8.2.2.p5, minus the crypto for the time being. The bind 
package does have BXA export approval, but the licensing strings on the
dnssafe code are a bit unpleasant.  The crypto is easy to restore and bind
will run without it - just without full dnssec support.
