scd: Split data structures into app and card related objects.
* scd/app-common.h (struct card_ctx_s): New. (struct app_ctx_s): Factor card specific fields out to card_ctx_s. (app_get_slot): New. * scd/scdaemon.h (card_t): New. (struct server_control_s): Rename field app_ctx to card_ctx and change all users. * scd/app-dinsig.c: Use app_get_slot and adjust for chang in card related fields. * scd/app-geldkarte.c: Ditto. * scd/app-nks.c: Ditto. * scd/app-openpgp.c: Ditto. * scd/app-p15.c: Ditto. * scd/app-sc-hsm.c: Ditto. * scd/app.c: Lost of changes to adjust for the changed data structures. Change all callers. (app_list_lock): Rename to card_list_lock. (app_top): Remove. (card_top): New. (lock_app): Rename to lock_card and change arg type. (unlock_app): Rename to unlock_card. (app_dump_state): Print card and app info. (app_reset): Rename to card_reset. (app_new_register): Change for the new data structure. (deallocate_card): Dealloc card and all apps. (app_ref): Rename to card_ref. (app_unref): Rename to card_unref. (app_unref_locked): Rename to card_unref_locked. (card_get_serialno): New. * scd/command.c (cmd_pkdecrypt): Actually use the looked up card and former app object and not the standard one from the context.
Although quite large, this is a straightforward change to separate
card/token related data from card application related data. Before
this change there was a one-to-one relation between card and
application and no way to represent several applications on a card.
The new data structure will allow for such a representation.
