Comment (by warner):

 looks good, I'll land it in a minute.

 Still to do for this ticket:

 * `tahoe create-node --hostname=` should detect if v6 is available, then
 write out a `tub.port =` with both `tcp:PORT` and `tcp6:PORT`. Or maybe we
 don't need to detect anything first? We must make sure the node won't
 crash at startup if v6 is not available, which means we need a host
 without v6 support to learn what sort of exception might get raised.
 * Add something to the docs about v6, explaining A/AAAA DNS records,
 bracketed IPv6 address hints, and warning that the endpoints in tub.port
 cannot include commas (because we stole them for delimiters between
 multiple endpoints)
 * wait for a foolscap release (with the bracketed-v6 parser) and bump the
 tahoe dependency to require it
