0041aeb751 Use dns_fixedname_initname() where possible
Replace dns_fixedname_init() calls followed by dns_fixedname_name()
calls with calls to dns_fixedname_initname() where it is possible
without affecting current behavior and/or performance.

This patch was mostly prepared using Coccinelle and the following
semantic patch:

    @@
    expression fixedname, name;
    @@
    -	dns_fixedname_init(&fixedname);
    	...
    -	name = dns_fixedname_name(&fixedname);
    +	name = dns_fixedname_initname(&fixedname);

The resulting set of changes was then manually reviewed to exclude false
positives and apply minor tweaks.

It is likely that more occurrences of this pattern can be refactored in
an identical way.  This commit only takes care of the low-hanging fruit.

590f092e00 Fix MX checks for dynamic updates
The check_mx() function in lib/ns/update.c incorrectly tests whether the
DNS_RDATA_CHECKMX/DNS_RDATA_CHECKMXFAIL flags are set for each applied
MX record update as these flags are never set in code paths related to
dynamic updates; they can only be set when loading a zone from a master
file (DNS_ZONEOPT_CHECKMX -> DNS_MASTER_CHECKMX -> DNS_RDATA_CHECKMX).
This flaw allows MX records containing IP addresses to be added to a
zone even when "check-mx fail;" is used.

Ensure correct behavior by modifying the relevant tests in check_mx() so
that they use DNS_ZONEOPT_CHECKMX/DNS_ZONEOPT_CHECKMXFAIL instead.

995c41e8f0 [master] further restrict update-policy local
4762.	[func]		"update-policy local" is now restricted to updates
			from local addresses. (Previously, other addresses
			were allowed so long as updates were signed by the
			local session key.) [RT #45492]

8eb88aafee [master] add libns and remove liblwres
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.
