scd: PC/SC pinpad support. (Backported from master.)
* iso7816.h (iso7816_verify_kp): Remove arguments of CHV and CHVLEN. * iso7816.c (iso7816_verify_kp): Call apdu_keypad_verify. Only handle thecase with PININFO. (iso7816_verify): Call apdu_send_simple. * app-openpgp.c (verify_a_chv, verify_chv3): Follow the change of iso7816_verify_kp. * app-nks.c (verify_pin): Likewise. * app-dinsig.c (verify_pin): Likewise. * apdu.c: Include "iso7816.h". (struct reader_table_s): New memeber function keypad_verify. Add fields verify_ioctl and modify_ioctl in pcsc. (CM_IOCTL_GET_FEATURE_REQUEST, FEATURE_VERIFY_PIN_DIRECT) (FEATURE_MODIFY_PIN_DIRECT): New. (pcsc_control): New. (control_pcsc_direct, control_pcsc_wrapped, control_pcsc) (check_pcsc_keypad, pcsc_keypad_verify): New. (ccid_keypad_verify, apdu_keypad_verify): New. (new_reader_slot): Initialize with check_pcsc_keypad, pcsc_keypad_verify, verify_ioctl and modify_ioctl. (open_ct_reader): Initialize keypad_verify with NULL. (open_ccid_reader): Initialize keypad_verify. (open_rapdu_reader): Initialize keypad_verify with NULL. (apdu_open_reader): Initialize pcsc_control. * pcsc-wrapper.c (load_pcsc_driver): Initialize pcsc_control. (handle_control): New. (main): Handle the case 6 of handle_control.
