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.
