The libirs version of getaddrinfo() cannot be called from within BIND9.

4713.	[func]		Added support for the DNS Response Policy Service
			(DNSRPS) API, which allows named to use an external
			response policy daemon when built with
			"configure --enable-dnsrps".  Thanks to Vernon
			Schryver and Farsight Security. [RT #43376]

4712.	[bug]		"dig +domain" and "dig +search" didn't retain the
			search domain when retrying with TCP. [RT #45547]

4711.	[test]		Some RR types were missing from genzones.sh.
			[RT #45782]

4709.	[cleanup]	Use dns_name_fullhash() to hash names for RRL.

4708.   [cleanup]       Legacy Windows builds (i.e. for XP and earlier)
                        are no longer supported. [RT #45186]

4707.	[func]		The lightweight resolver daemon and library (lwresd
			and liblwres) have been removed. [RT #45186]

4706.	[func]		Code implementing name server query processing has
			been moved from bin/named to a new library "libns".
			Functions remaining in bin/named are now prefixed
			with "named_" rather than "ns_".  This will make it
			easier to write unit tests for name server code, or
			link name server functionality into new tools.
