How to build up a DNS trie from separate RRs.

type db = {

trie : Trie.dnstrie;
mutable names : (Name.key, RR.dnsnode) Hashtbl.t;

}

Loader database: the DNS trie plus a hash table of other names in use.

val new_db : unit -> db

Make a new, empty database.

val no_more_updates : db -> unit

Call when guaranteed there will be no more updates.

Insert RRs in the database: args are rdata, ttl, owner, db.

exception TTLMismatch

Raised if we already had an RRSet for this name and type, but with a different TTL. Also possible: Trie.BadName.

N.B. If TTLMismatch is raised, the RR was successfully added, and the RRSet now has the new ttl.
