gpg: Rename the struct card_key_info_s.

* g10/call-agent.h (struct card_key_info_s): Rename to ...
(struct keypair_info_s): this.
(keypair_info_t): New.  Use this everywhere instead of
card_key_info_s.
* g10/call-agent.c (agent_scd_free_keyinfo): Rename to ..
(free_keypair_info): this.  Change all callers.
--

The struct is also useful to store the data from KEYPAIRINFO status
lines.  Thus renaming it makes sense.  A future patch will extend the
struct.
