* agent/call-scd.c (agent_card_serialno): Allow NULL for R_SERIAL.
(struct readkey_status_parm_s): New.
(readkey_status_cb): New.
(agent_card_readkey): Add optional arg R_KEYREF and change all
callers.
* agent/findkey.c (key_parms_from_sexp): Allow also a "public-key".
* agent/divert-scd.c (ask_for_card): Allow for SHADOW_INFO being NULL.
* agent/pksign.c (agent_pksign_do): Fallback to sign with an on-card

misnaming between s_pkey and s_skey.

first making sure that a stub key exists. It is also the less
surprising behaviour.
