Browse Source 
* scd/apdu.c (ccid_keypad_operation): Rename from ccid_keypad_verify.
(open_ccid_reader): Use ccid_keypad_operation for verify and modify.

* scd/ccid-driver.c (VENDOR_VASCO, VASCO_920): New.
(ccid_transceive_apdu_level): Permit sending packet where
apdulen <= 289.  Support receiving packets in a chain.
(ccid_transceive_secure): Maximum is 15 for VASCO DIGIPASS 920.
Support keypad_modify method such as CHANGE_REFERENCE_DATA: 0x24.
