	(nml_read_obj): Add nml_err_msg_size argument.  Pass it down to

	is used.
	(nml_get_obj_data): Add nml_err_msg_size argument.  Pass it down to
	nml_read_obj call.  Use snprintf instead of sprintf when %s
	nl->var_name is used.  Pass nml_err_msg to nml_parse_qualifier instead
	of parse_err_msg array.  Append " for namelist variable " and
	nl->var_name to it.
	(namelist_read): Increase size of nml_err_msg array to 200.  Pass
