* gpgv.c (agent_scd_getattr): Stub.

* misc.c (get_signature_count): New.  Get the signature count from a
smartcard. (pct_expando): Call it here so the %c expando becomes the
number of signatures issued.  This allows for notations or the like with
an automatic signature count.

* ccid-driver.c (usb_get_string_simple): Replacement function to work with
older libusb.
