Add option type OPTION_ORDER

To handle incremental order value, added new option type OPTION_ORDER.
openssl(1) x509 requires this option handling, since,
- -CA and -signkey require to set both filename and incremental 'num'.
- -dates requires to set two variables in a row, startdate and enddate.
and this couldn't be solved by OPTION_FLAG_ORD.
