ntdb: special accessor functions for read/write of an offset.
We also split off the NTDB_CONVERT case (where the ntdb is of a
different endian) into its own io function.
NTDB speed:
Adding 10000 records: 3894-9951(8553) ns (815528 bytes)
Finding 10000 records: 1644-4294(3580) ns (815528 bytes)
Missing 10000 records: 1497-4018(3303) ns (815528 bytes)
Traversing 10000 records: 1585-4225(3505) ns (815528 bytes)
Deleting 10000 records: 3088-8154(6927) ns (815528 bytes)
Re-adding 10000 records: 3192-8308(7089) ns (815528 bytes)
