ebdecebb1a channeld: send channel_announce and initial update to master, not gossipd.
There is a race we see sometimes under valgrind on Travis which shows
gossipd receiving the node_announce from master before it reads the
channel_announce from channeld, and thus fails.  The simplest solution
is to send the channel_announce and channel_update to master as well,
so it can ensure it sends them to gossipd in order

7e022b522c gossipd: don't try to handle padding inside fromwire_ipaddr.
It makes it impossible to embed an ipaddr in another structure, since we
always try to skip over any zeroes, which may swallow a following field.

Do the skip specially for the case where we're parsing routing messages:
we never use padding for our own internal messages anyway.

c3bed51b2d test_lightningd.py: make HSM seeds constant for tests.
Makes it easier to compare before/after failures.  Ideally, we should
run under Travis both with this option and with the seed based on the
entire tmp path (which is still reproducible with determination, but
not fixed every run like this is).

5a256c724a subd: simplify and cleanup lifetime handling.
There are now only two kinds of subdaemons: global ones (hsmd, gossipd) and
per-peer ones.  We can handle many callbacks internally now.

We can have a handler to set a new peer owner, and automatically do
the cleanup of the old one if necessary, since we now know which ones
are per-peer.

cb82bf7aa2 onchaind: send message when peer's transactions are irrevocably committed.
We currently rely on a zero exit status.  That's the only difference between
onchain finished handling and other per-peer daemons, so instead we should
have an explicit "done" message.  This is both clearer, and allows us to
unify.

474887512d gossipd: rewrite to do the handshake internally.
Now the flow is much simpler from a lightningd POV:

1. If we want to connect to a peer, just send gossipd `gossipctl_reach_peer`.
2. Every new peer, gossipd hands up to lightningd, with global/local features
   and the peer fd and a gossip fd using `gossip_peer_connected`
3. If lightningd doesn't want it, it just hands the peerfd and global/local
   features back to gossipd using `gossipctl_handle_peer`
4. If a peer sends a non-gossip msg (eg `open_channel`) the gossipd sends
   it up using `gossip_peer_nongossip`.
5. If lightningd wants to fund a channel, it simply calls `release_channel`.

Notes:
* There's no more "unique_id": we use the peer id.
* For the moment, we don't ask gossipd when we're told to list peers, so
  connected peers without a channel don't appear in the JSON getpeers API.
* We add a `gossipctl_peer_addrhint` for the moment, so you can connect to
  a specific ip/port, but using other sources is a TODO.
* We now (correctly) only give up on reaching a peer after we exchange init
  messages, which changes the test_disconnect case.

871d0b1d74 lightningd: simplify peer destruction.
We have to do a dance when we get a reconnect in openingd, because we
don't normally expect to free both owner and peer.  It's a layering
violation: freeing a peer should clean up the owner's pointer to it,
to avoid a double free, and we can eliminate this dance.

The free order is now different, and the test_reconnect_openingd was
overprecise.

c6f210a46c htlcs: Needed to add origin_htlc_id to outgoing HTLCs
While loading HTLCs from the database we might not yet have all the
incoming HTLCs loaded when loading a dependent htlc_out. So we defer
the wiring of the HTLCs until we are sure we have them loaded.

This is also the first step towards keeping that association only in
the database, since otherwise we cannot selectively load channels from
DB.
