   IsDumpRequired - return TRUE if symbol sym should be dumped

                    of the list can specify a symbol three ways.
                    Firstly by DECL name for example: m2pim_NumberIO_HexToStr
                    Secondly by qualified scope: [pathname.]NumberIO.HexToStr
                    Thirdly by filename and scope: NumberIO.mod:HexToStr
