We need to do this on every connection, whether reconnecting or not,
so it makes sense for the handshake daemon to handle it and return
the feature fields.
Longer term I'm considering having the handshake daemon handle the
listening and connecting, and simply hand the fds back once the peers
are ready.

We currently create a peer struct, then complete handshake to find out
who it is. This means we have a half-formed peer, and worse: if it's
a reconnect we get two peers the same.
Add an explicit 'struct connection' for the handshake phase, and
construct a 'struct peer' once that's done.
