Bo Yang 3fd699ed44 parse-options: add two helper functions ...

1. parse_options_current: get the current option/argument the API
   is dealing with;
2. parse_options_next: skip the current argument, moving to the
   next one. Unless 'keep' is set, discard the skipped argument
   from the final argument list.
