* scd/ccid-driver.c (USE_LIBUSB_DEBUG_CB): New const.
(debug_libusb_cb): new.
(ccid_set_debug_level): Use it.
--
This allows to see the libusb log in our usual debug output. For this
the option debug-ccid-driver needs to be given 5 or more times.
* scd/ccid-driver.c (ccid_dev_scan): Use loop var and not the count.
--
Due to an assignment out of bounds this might lead to a crash if there
are more than 15 readers. In any case it fixes a memory leak.
Kudos to the friendly auditor who found that bug.

* scd/ccid-driver.c (ccid_require_get_status): For VENDOR_SCM reader,
return 0 only at the initial call.
(bulk_in): Don't detect an error for VENDOR_SCM reader, just kicking
the loop, to invoke scd_update_reader_status_file, which calls
ccid_slot_status again.
(ccid_slot_status): Move the call of ccid_vendor_specific_setup to...
(ccid_get_atr): ... here.
--
For readers with interrupt transfer support, it is only intr_cb which
sets handle->powered_off to 1. Keeping this condition makes no race.
The function ccid_slot_status can also detect a communication error,
which causes apdu_close_reader (but not setting ->powered_off).

SPR532 USB Smart Card Reader (also know as SPR332) may send two
messages at once for a single interrupt transfer. An example transfer
observed was like: 50 03 50 02, which is considered valid, according
to the CCID specification.

This handling is not mondatory, but it's better to do so, because
there are card reader with pinpad and token with ack button, which
support user interaction.
User interaction status should be reset at open time. The status
should be reset when the session is closed/stopped. In practice,
since cleanup routine in a driver may not be called properly, it's
good to submit SET_INTERFACE at open time.

We can use the interrupt transfer to be notified about card status
change. In this case, we don't need to issue PC_to_RDR_GetSlotStatus
command. This change improve the setup the notification; it should be
done after registration of APP.
When the setup is done just after opening the USB connection (before
issuing PC_to_RDR_IccPowerOn), a reader might notifies about no card
availability (because of not yet powered on), even though the card is
ready to be powered on.
