options: accept "yes" and "no" only for flags

This removes the alternative values like "off", "0", "false" etc., and
also the non-English versions of these.

This is done for general consistency. It's better to have a single way
of doing things when multiple ways don't add singificant value.

Also update some choices for consistency.
