Rusty Russell aa6aad0131 common: add struct onionreply
I really want a type which means "I am a wrapped onion reply" as separate
from "I am a normal wire msg".  Currently both user u8 *, and I got very
confused trying to figure out where each one was an unwrapped error msg,
or where it still needed (un)wrapping.
