../g10/call-agent.c

(ssh_handler_request_identities): First see whether a card key is
available.

* app.c (app_getattr): Return APPTYPE or SERIALNO type even if the
application does dot support the getattr call.

* app.c (select_application): Return an error code and the
application context in an new arg.
* command.c (open_card): Adjusted for that.  Don't use the
