Test objects must be added to $(ALL_OBJS) so they correctly depend on
CCAN headers etc.
Also, each test in a subdir must depend on headers and src in the parent
directory, as it will often #include them directly.

There were two bugs: we weren't returning the next from the given

invoices to the head instead of the tail, which meant we'd be

Normally, we get an error as soon as we send WIRE_REVOKE_AND_ACK. But if the
commit timer goes off, we get some extra cycles, during which the other side
can reconnect. In this case, we simply kill the channeld before it fails,
and never check for the permfail string.

This is a bit messier than I'd like, but we want to clearly remove all
dev code (not just have it uncalled), so we remove fields and functions
altogether rather than stub them out. This means we put #ifdefs in callers
in some places, but at least it's explicit.
We still run tests, but only a subset, and we run with NO_VALGRIND under
Travis to avoid increasing test times too much.

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

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.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
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).

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.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
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.

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.

We're going to make the ip/port optional, so they should go at the end.
In addition, using ip:port is nicer, for gethostbyaddr().

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.

This fixes the only case where the master currently has to write directly
to the peer: re-sending an error. We make gossipd do it, by adding
a new gossipctl_fail_peer message.
