	* engine-gpgsm.c (struct engine_gpgsm): Move members
	input_fd_server, output_fd_server, message_fd_server to ...
	(iocb_data): ... here (as server_fd).
	(close_notify_handler): Reset tags as well.
	(gpgsm_new): Implement support for descriptor
	passing.
	(fd_type_t): New type.
	(gpgsm_clear_fd): New function.  Use it instead of _gpgsm_io_close
	for unused communication channels.
	(gpgsm_set_fd): Rewritten to support descriptor passing.  All
	relevant callers adjusted as well (previously of _gpgme_io_close).
