scd: Only submit apdu_get_status when needed.

Browse source 
* scd/apdu.c (apdu_dev_list_finish): Return Boolean value if
all device support INTERRUPT transfer.
* scd/ccid-driver.c (ccid_dev_scan_finish): Likewise.
* scd/app.c (app_new_register): Fix initial value of card_status.
(select_application): Call update_fdset_for_usb.
(scd_update_reader_status_file): Ditto.
* scd/scdaemon.c (update_fdset_for_usb, need_tick): New.
(handle_connections): Call handle_tick when select returns.
Let select watch USB file descriptors, too.
Call libusb_handle_events_timeout_completed for INTERRUPT transfer.
