gpg: Let --card--status create a shadow key (card key stub).

* agent/command.c (cmd_learn): Add option --sendinfo.
* agent/learncard.c (agent_handle_learn): Add arg "send" andsend
certifciate only if that is set.
* g10/call-agent.c (agent_scd_learn): Use --sendinfo.  Make INFO
optional.
(agent_learn): Remove.
* g10/keygen.c (gen_card_key): Replace agent_learn by agent_scd_learn.

The requirement of using --card-status on the first use of card on a
new box is a bit annoying but the alternative of always checking
whether a card is available before a decryption starts does not sound
promising either.
