s4:objectclass_attrs LDB module - move the single-valued attribute check into this module
It seems to me more consistent (and also to keep the same behaviour on all backends). Also the DRS hack should therefore not be needed anymore since the "repl_meta_data" module launches requests behind "objectclass_attrs".
