[master] add libns and remove liblwres

Browse Source 
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.
			[RT #45186]
