function   : bd90UpdateObj

description: Replaces the current image of an object by a new one

arguments  : Current          [in/out]  handle of the task context and the fileid
             OId              [in]      OId of the frame containing the object to be updated
             ObjVers          [in/out]  Version of the object which shall be updated. Only if the given Version corresponds to the
                                        Version of the current image of the object the object can be updated otherwise the error 
                                        e_object_dirty is returned
                                                      After this operation ObjVers contains the version of the updated object image
             NewObjBodyLen    [in]     Length of the new object image replacing the old image of the object
             pNewObjBody       [in]     Pointer to the new object image
                   RedoEntrySequence [in]     if RedoEntrySequence is invalid this update is a normal (online) update
                                              but if it has a valid value this is a rollforward of an update operation during a restart 
                                                            which differs from a normal update by a fact that no history data is written and 
                                                            by a differnt check whether the update is allowed
             RedoUpdTransNo    [in]     in case that that the operation is a rollforward of an update this is 
                                              update transno of the transaction which originally updated the object othwerwise
                                                            this parameter has no meaning
