s4:dsdb Handle dc/domain/forest functional levels properly
Rather than have the functional levels scattered in 4 different, unconnected locations, the provision script now sets it, and the rootdse module maintains it's copy only as a cached view onto the original values. We also use the functional level to determine if we should store AES Kerberos keys. Andrew Bartlett
