-Subject: [PATCH 19/32] Tidy address-union handling: move class into explicit
- argument.
-
-This moves the class argument to cache-insert into an argument,
-rather then overloading a union in the address argument. Note that
-tha class is NOT stored in the cache other than for DS/DNSKEY entries,
-so must always be C_IN except for these. The data-extraction code
-ensures this as it only attempts to cache C_IN class records.
