/**
* Check if there is a backup file.
* May only be used on fresh installations (eg. dc_is_configured() returns 0).
*
* Example:
*
* ~~~
* char dir[] = "/dir/to/search/backups/in";
*
* void ask_user_for_credentials()
* {
* // - ask the user for email and password
* // - save them using dc_set_config()
* }
*
* int ask_user_whether_to_import()
* {
* // - inform the user that we've found a backup
* // - ask if he want to import it
* // - return 1 to import, 0 to skip
* return 1;
* }
*
* if (!dc_is_configured(context))

* char* file = NULL;
* if ((file=dc_imex_has_backup(context, dir))!=NULL && ask_user_whether_to_import())
* {
* dc_imex(context, DC_IMEX_IMPORT_BACKUP, file, NULL);

* @memberof dc_context_t
* @param context The context as created by dc_context_new().
* @param dir_name Directory to search backups in.
* @return String with the backup file, typically given to dc_imex(), returned strings must be free()'d.
* The function returns NULL if no backup was found.
