scd: Convey the correct length for Le
* scd/app-openpgp.c (determine_rsa_response): Round bits up.
--

Co-authored-by: Arnaud Fontaine <arnaud.fontaine@ssi.gouv.fr>

Arnaud wrote:

  Actually, when the incorrect expected response length (i.e. Le
  field) is transmitted to the card, the card's answer is missing a
  byte (i.e. ...  6101) so an additional command has to be sent to the
  card to retrieve the last byte. Using the correct length avoids to
  send the additional command to retrieve the missing byte, when the
  computed length is wrong.

Note that an value of 65537 for E is pretty standard and thus we can
avoid the 6101 return code inmost cases.

(get_escaped_usb_string): Insert npth_unprotect/npth_protect.
(do_close_reader, bulk_out, bulk_in, abort_cmd, ccid_slot_status)
(ccid_transceive, ccid_transceive_secure): Likewise.

It found that libusb_get_pollfds is not supported on Windows.
Besides, it's a bit difficult to use for the select loop.
Thus, we use the thread named ccid_usb_thread, instead.

f92fe33f11 scd: Fix release of transfer object.
* scd/ccid-driver.c (intr_cb): Handle LIBUSB_TRANSFER_CANCELLED.
(do_close_reader): When callback is active, call
libusb_cancel_transfer and wait callback is fired off.

25cc8575da 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.

031e3fa7b9 scd: Wake up the select when new USB scan.
* scd/scdaemon.c (update_fdset_for_usb): Wake up the select(2).
(handle_connections): Use a kind of "self-pipe" technique.

--

Use pipe to wake up select(2).  If UNIX-only, signal could be used.  For
portability, "self-pipe" is better, here.  Setup for non-blocking for
pipe fds are not needed, because speed of USB device insertion is
limited by human physical interaction;  No one can do hundreds of
device insertion/removal-s per second.
