card: Better detect removed cards. Add TCOS PIN menu.
* tools/card-call-scd.c (scd_change_pin): Add arg 'nullpin'. * tools/gpg-card.h (struct card_info_s): Add field 'card_removed'. * tools/gpg-card.c (fixup_scd_errors): New. (maybe_set_card_removed): New. (list_one_kinfo): Change type of first arg to get access to INFO. Set card_removed flag. (list_all_kinfo): Improve label alignment. (cmd_list): Check that the current card is still available. (cmd_passwd): Add option --nullpin and menu to chnage TCOS PINs. (dispatch_command): Handle card_removed flag. (interactive_loop): Ditto.
Note that that I was not able to change the NullPIN of the standard
PIN using a Signature V2 Brainpool test card. Changing the NullPIN of
the QES PIN worked, though. I checked the commands send to scdaemon
and they were correct - I used the very same command with
gpg-connect-agent last week to set a Pin for a production Brainpool
Signature card. Thus this might be a problem with this specific test
card.
