After quite some back and forth we seem to finally agree on the bit
3 (mask 0x08) to signal optional initial_routing_sync.

We support a number of features already, so failing connections
whenever we see an even bit set is not a good idea. This turned out to
kill our connections to eclair.
Also, the spec says that the LSB / bit 0 is to be counted as index 0, and
therefore even. So we need to check the lower of each 2-bit-tuple not
the higher one.
Now we're always sync, just use an fd. Put the hsm_sync_read() helper
here, too, and do HSM init sync which makes things much simpler.

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.
