This looks pretty simple so far.

There are some tdb-specific assumptions in dbwrap, but the translation
should be fine (eg. db_opsn's hash_size, which is irrelevant for tdb2,
and tdb_flags, which are the tdb1 flags).
I guess it doesn't *have to* be 100%, if we end up using direct tdb2 for
some temporary databases.
