Rusty Russell 693457a580 lightningd: remove unused offset field from CSV files.
The format we use to generate marshal/unmarshal code is from
the spec's tools/extract-formats.py which includes the offset:
we don't use it at all, so rather than having manually-calculated
(and thus probably wrong) values, or 0, emit it altogther.

Rusty Russell ccad93edb3 gossipd: add fail_peer.
We use this if it reconnects via another fd.

Rusty Russell 662dfef436 lightningd/gossip: Move INIT message handling to handshake daemon.
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.

Christian Decker daf8866eb5 gossip: Implement the basic node_announcement
Rather a big commit, but I couldn't figure out how to split it
nicely. It introduces a new message from the channel to the master
signaling that the channel has been announced, so that the master can
take care of announcing the node itself. A provisorial announcement is
created and passed to the HSM, which signs it and passes it back to
the master. Finally the master injects it into gossipd which will take
care of broadcasting it.

Rusty Russell cd90c8408c lightningd/gossip: clean up channel resolve failure handling.
We were getting an assert "!secp256k1_fe_is_zero(&ge->x)", because
an all-zero pubkey is invalid.  We allow marshal/unmarshal of NULL for
now, and clean up the error handling.

1. Use status_failed if master sends a bad message.
2. Similarly, kill the gossip daemon if it gives a bad reply.
3. Use an array for returned pubkeys: 0 or 2.
4. Use type_to_string(trc, struct short_channel_id, &scid) for tracing.

Christian Decker 25f1cba3cf routing: Ask gossipd to resolve channel_id and forward HTLCs
Since we now use the short_channel_id to identify the next hop we need
to resolve the channel_id to the pubkey of the next hop. This is done
by calling out to `gossipd` and stuffing the necessary information
into `htlc_end` and recovering it from there once we receive a reply.

Christian Decker b4beab6537 gossip: Make the broadcast interval configurable
Adds a new command line flag `--dev-broadcast-interval=<ms>` that
allows us to specify how often the staggered broadcast should
trigger. The value is passed down to `gossipd` via an init message.

This is mainly useful for integration tests, since we do not want to
wait forever for gossip to propagate.

Rusty Russell f511012e29 lightningd/gossip: don't hand client fd until release.
The gossip subdaemon previously passed the fd after init: this is
unnecessary for peers which simply want to gossip (and not establish
channels).

Now we hand the gossip fd back with the peer fd.  This adds another
error message for when we fail to create the gossip fds.

Rusty Russell de651bf8fb gossip: don't use hand-coded nested messages for getnodes array.
We can simply tell it 'nodes' is 'num_nodes*struct gossip_getnodes_entry'.

Rusty Russell e042198cf8 tools/generate-wire.py: allow typename instead of type sizes.
We use the fourth value (size) to determine the type, unless the fifth
value is suppled.  That's silly: allow the fourth value to be a typename,
since that's the only reason we care about the size at all!

Unfortunately there are places in the spec where we use a raw fieldname
without '*1' for a length, so we have to distingish this from the
typename case.
