sm: Fix finding of issuer in use-keyboxd mode.

Browse Source 
* sm/keydb.c (struct keydb_local_s): Add field saved_search_result.
(keydb_push_found_state): Implement for keyboxd.
(keydb_pop_found_state): Ditto.
(keydb_get_cert): Do not release the cert so that the function can be
used again to get the same cert.  This is the same behaviour as in
pubring.kbx mode.

* sm/certchain.c, sm/import.c: Improve some error messages.
