card: New command "apdu"
* tools/card-call-scd.c (scd_apdu): Add optional arg 'options'. * tools/gpg-card.c (cmd_apdu): New. (enum cmdids): Add cmdAPDU. (dispatch_command): Add command "apdu". (interactive_loop): Ditto.
This command is hidden because it can be used to brick a card. The
command is basically the same as sending "scd apdu" in
gpg-connect-agent but here we do full decoding and printing in hex.
