Here is a patch to allow 'on' and 'off' as input texts for boolean.
Duplicated boolean parsers in parse_bool() and boolin() are merged
into a new parse_bool_with_len().
I think the change is useful when we treat reloptions in programs.
Since human-readable texts are not suitable for programs, we would need
conversions from text to boolean. Then the shared parser works well.
