* scd/app.c (lock_app): Rename from lock_reader and use internal field of APP. (unlock_app): Likewise. (app_dump_state): Use APP. (application_notify_card_reset): Remove. (check_conflict): Change API for APP, instead of SLOT. (check_application_conflict): Likewise. (release_application_internal): New. (app_reset): New. (app_new_register): New. (select_application): Change API for APP, instead of SLOT. (deallocate_app, release_application): Modify for manage link. (report_change): New. (scd_update_reader_status_file): Moved from command.c and use APP list, instead of VREADER. (initialize_module_command): Moved from command.c. * scd/command.c (TEST_CARD_REMOVAL): Remove. (IS_LOCKED): Simplify. (vreader_table): Remove. (vreader_slot, update_card_removed): Remove. (do_reset): Call app_reset. (get_current_reader): Remove. (open_card): Add SCAN arg. (cmd_serialno): No retry, since retry is done in lower layer in apdu.c. No do_reset, since it is done in lower layer. Add clearing card_removed flag. (cmd_disconnect): Call apdu_disconnect. (send_client_notifications): Modify for APP. (update_reader_status_file): Remove. -- APP is the abstraction of the card application. For management of cards, it is better to focus on the APP instead of the physical reader. This change makes support of multiple card/token easier. Signed-off-by: NIIBE Yutaka <gniibe@fsij.org>
