Seems good, but namecache filename is a bit misleading, since quite
a lot of other things would be cached there. Much more than just
netbios names and trusted domains - it's just a matter of time.
Current API is quite good, but more stored values specific functions
need to be added (like storing entire unicode trusted domain name or
any other structures). Also, tdb packing/unpacking might be used, though
cache files are not critical when it comes to portability.
