I am adding PIN pad support to Gnuk.  I did some experiments and found
things.  Here is the summary of PIN pad support status.  Please
correct me, if I'm wrong.

  * PIN pad support is only available for GnuPG's in-stock ccid-driver.

  * It is not available for PC/SC lite backend (yet).

  * It is only used for VERIFY command.

    Yes, we have the functions iso7816_change_reference_data_kp and
    iso7816_reset_retry_counter_kp, but callers are not yet
    implemented to support PIN pad.

  * ccid-driver only support a few readers for PIN pad.

    I needed following patch for Gnuk.
