net/bind918: update to 9.18.13

--- 9.18.13 released ---

6120.	[bug]		Use two pairs of dns_db_t and dns_dbversion_t in a
			catalog zone structure to avoid a race between the
			dns__catz_update_cb() and dns_catz_dbupdate_callback()
			functions. [GL #3907]

6119.	[bug]		Make sure to revert the reconfigured zones to the
			previous version of the view, when the new view
			reconfiguration fails during the configuration of
			one of the configured zones. [GL #3911]

6116.	[bug]		Fix error path cleanup issues in dns_catz_new_zones()
			and dns_catz_new_zone() functions. [GL #3900]

6115.	[bug]		Unregister db update notify callback before detaching
			from the previous db inside the catz update notify
			callback. [GL #3777]

6114.	[func]		Run the catalog zone update process on the offload
			threads. [GL #3881]

6113.	[func]		Add shutdown signaling for catalog zones. [GL !7571]

6112.	[func]		Add reference count tracing for dns_catz_zone_t and
			dns_catz_zones_t. [GL !7570]

6105.	[bug]		Detach 'rpzs' and 'catzs' from the previous view in
			configure_rpz() and configure_catz(), respectively,
			just after attaching it to the new view. [GL #3880]

6098.	[test]		Don't test HMAC-MD5 when not supported by libcrypto.
			[GL #3871]

6096.	[bug]		Fix RPZ reference counting error on shutdown in
			dns__rpz_timer_cb(). [GL #3866]

6095.	[test]		Test various 'islands of trust' configurations when
			using managed keys. [GL #3662]

6094.	[bug]		Building against (or running with) libuv versions
			1.35.0 and 1.36.0 is now a fatal error.  The rules for
			mixing and matching compile-time and run-time libuv
			versions have been tightened for libuv versions between
			1.35.0 and 1.40.0. [GL #3840]

6092.	[bug]		dnssec-cds failed to cleanup properly. [GL #3831]

6089.	[bug]		Source ports configured for query-source,
			transfer-source, etc, were being ignored. (This
			feature is deprecated, but it is not yet removed,
			so the bug still needed fixing.) [GL #3790]
