scd: Improve watching USB device removal.

* scd/apdu.c(struct reader_table_s): Add require_get_status.
(apdu_connect): Change return value meaning.  Call apdu_reset here.
* scd/app.c (app_new_register): Add require_get_status.
(select_application): Use the return value of apdu_connect.
(scd_update_reader_status_file): Call update_fdset_for_usb with
checking all_have_intr_endp.
(app_list_start, app_list_finish): Remove.
* scd/ccid-driver.c (struct ccid_driver_s): Add transfer.
(intr_cb): Don't call libusb_transfer in this callback.
(ccid_require_get_status): New.
(do_close_reader): Call libusb_transfer here.
* scd/scdaemon.c (update_fdset_for_usb): Remove the first argument.

--

With Gnuk Token, it works fine as expected.  With Gemalto reader,
intr_cb is not called when card is removed.  So, the macro
LIBUSB_WORKS_EXPECTED_FOR_INTERRUPT_ENDP is not defined yet.
