add dns_zone_isexpired API

Browse source 
Introduce the `dns_zone_isexpired()` API which returns `true` when a
secondary, mirror, etc. zone is expired.

This internally use the `DNS_ZONEFLG_EXPIRED` which was already set when
the zone gets expired, but never used.

The flag `DNS_ZONEFLG_EXPIRED` is also now cleared when the expiration
time of the zone is updated and in the future.
