Clean up option handling.

If the option length is >= 2, so that it's long enough to include the
code and length, always put it into the protocol tree, even if the
length is invalid.  If the length is invalid, attach an expert info item
to the length field, rather than putting it into a top-level item of its
own.

Use a length of -1 for the top-level item for an option, rather than
what the length is supposed to be; that way, we don't throw an exception
if the option is too short - we just attach the aforementioned expert
info item to the length.
