3933. [bug] Corrected the implementation of dns_rdata_casecompare()
for the HIP rdata type. [RT #36911]
3932. [test] Improved named-checkconf tests. [RT #36911]
(cherry picked from commit 0c2313eb36)
3746. [func] New "max-zone-ttl" option enforces maximum
TTLs for zones. If loading a zone containing a
higher TTL, the load fails. DDNS updates with
higher TTLs are accepted but the TTL is truncated.
(Note: Currently supported for master zones only;
inline-signing slaves will be added.) [RT #38405]
