s4:samldb - Major rework
This fixes up the change of the primary group of a user when using the ADUC console: - When the "primaryGroupId" attribute changes, we have to delete the "member"/"memberOf" attribute reference of the new primary group and add one for the old primary group. - Deny deletion of primary groups according to Windows Server (so we cannot have invalid "primaryGroupID" attributes in our AD). - We cannot add a primary group directly before it isn't a secondary one of a user account. - We cannot add a secondary reference ("member" attribute) when the group has been chosen as primary one. This also removes the LDB templates which are basically overhead now. This should also fix bug #6599.
