All that we need to change is the back-end for "dns" lookups for
those services (e.g, _dns_gethtbyname() et al).  That gives you
the resolver upgrade to "BIND 8" DNS lookups that you want want,
without all the other baggage that IRS comes with.  There's no
point in bringing in the entire IRS framework (to support switching
between dns, nis, and files) when our nsswitch framework already
supports such switching.
