Before, the status of the configuration check (config_def_check fn call) was saved directly in global configuration definitinion array (as part of the cfg_def_item_t/flags) This patch introduces the "struct cft_check_handle" that defines configuration check parameters as well as separate place to store the status (status here means CFG_USED and CFG_VALID flags, formerly saved in cfg_def_item_t/flags). This struct can hold config check parameters as well as the status for each config tree separately, thus making it possible to run several instances of config_def_check without interference.
