[master] fix dyndb issues; isc_errno_toresult()

4445.	[cleanup]	isc_errno_toresult() can now be used to call the
			formerly private function isc__errno2result().
			[RT #43050]

4444.	[bug]		Fixed some issues related to dyndb: A bug caused
			braces to be omitted when passing configuration text
			from named.conf to a dyndb driver, and there was a
			use-after-free in the sample dyndb driver. [RT #43050]

Patch for dyndb driver submitted by Petr Spacek at Red Hat.
