We should not disconnect from a peer just because it fails opening; we
should return it to gossipd, and give a meaningful error.

We don't use it yet, but now we'll decode correctly.

If you run locally, it fails occasionally; presumably because it
sees previous funds. Use a random HSM key for that teste.

I noticed some breakage with git master:
1. getinfo no longer supported (for us, use getblockchaininfo)
2. generate no longer supported (use generatetoaddress)
Both these options are supported at least in 0.15, too.

This seems to happen when we manage to check between the
channel_announcement and the channel_update being processed.

Add two simple tests: one for a single direct payment and one with
hundreds of parallel payments, reusing the same route.
Signed-off-by: Christian Decker <decker.christian@gmail.com>
We are announcing that we are willing to accept incoming payments with
current_height + min_final_cltv_expiry + slack, assuming that the
sender adds some slack. In particular we'd reject the payment if
slack=0 which is allowed by the spec.

Raising the exception about non-zero exit values into the
teardown. This was previously masking the valgrind errors. Now
valgrind errors > crash errors > non-zero return value.
Still hoping to catch that elusive [7, 0] return value on travis.

These need to be different for testing the example in BOLT 11.
We also use the cltv_final instead of deadline_blocks in the final hop:
various tests assumed 5 was OK, so we tweak utils.py.

I run with ulimit -c unlimited, and valgrind leaves core files like
valgrind-errors.22114.core.22114 which test_lightning.py tries to
parse as log files.

It crashes under valgrind, causing a valgrind error: valgrind gives us a
backtrace anyway, so we don't need it.

And we report these through the getpeers JSON RPC again (carefully: in
our reconnect tests we can get duplicates which this patch now filters
out).

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 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.

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 currently assume the daemon gives up; gossipd won't, and we want to
test it there too.
This reveals a bug (returning io_close() is bad if the call is to
duplex()), and breaks a test which now continues after dropping a
packet..
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Useful if we want to drop & suppress, for example. We change '=' to mean
do nothing to the packet.
We use this to clean up the test_reconnect_sender_add test.

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.

Now that we have HTLC persistence we'd also like to test it. This
kills the second node in the middle of an HTLC, it'll recover and
finish the flow.

Moved the flagging for allowed failures into the factory getter, and
renamed into `may_fail`. Also stopped the teardown of a node from
throwing an exception if we are allowed to exit non-cleanly.

A failed returncode check could result in the cleanup for other
lightningds to be skipped. Now make sure to cleanup all and then
rethrow an exception that contains all returncodes.

We used to simply kill the daemon, which in some cases could result in
half-written crashlogs and similar artifacts such as half-completed
RPC calls. Now we ask lightningd to stop nicely, give it some time and
only then kill it. We also return the returncode of the daemon.
