Good idea. I've done so.

It looks like they are called "options" in most places. I changed the
documentation to be consistent too.

This is not going to be correct because not all options do require a
protocol version. "origin" is added in version 16, but doesn't check
for any "proto_version". Perhaps we should fix this too.

Done.

Thanks for the review.

The new versions are attached.
