This is to update configure.in so that configure checks for the existence
of res_nmkquery, res_nsend, and dn_expand which are needed by
dns_getrecord()..... which is appearantly going to be dns_get_record
now....
Speaking of which I've also attached dns_get_record.patch.txt to update my
previous patch which introduced the function as dns_getrecord
Pasting as text as well because of recent not-always-attaching issues in
my mail client.
