Subject: Rework Samba3 to use new libcli/auth code (partial)

This commit is mostly to cope with the removal of SamOemHash (replaced
by arcfour_crypt()) and other collisions (such as changed function
arguments compared to Samba3).

We still provide creds_hash3 until Samba3 uses the credentials code in
netlogon server
