Currently it's fairly ad-hoc, but we need to tell it to channeld when
it restarts, so we define it as the non-HTLC balance.

When adding their HTLCs, it needs all the information. When failing,
it needs the id as key and the failure reason. When fulfilling, it
needs the id and payment preimage.
It also needs to know when we have received an revoke_and_ack or a
commitment_signed, to place in the database.

I have a test which waits for multiple occurrences of the same string,
but doesn't want them to overlap. Make wait_for_log() do the right thing,
so that it only looks for log entries since the last wait_for_log.

On my laptop under load, 5 seconds was no longer enough for legacy.
But this breaks async (they all see mempool increase, and fire
prematurely), so stop doing that.
I can't get this test to work at all, in fact, without this patch.

I actually hit this very hard to reproduce race: if we haven't process
the channeld message when block #6 comes in, we won't send the gossip
message. We wait for logs, but don't generate new blocks, and timeout
on l1.daemon.wait_for_log('peer_out WIRE_ANNOUNCEMENT_SIGNATURES').
The solution, which also tests that we don't send announcement signatures
immediately, is to generate a single block, wait for CHANNELD_NORMAL,
then (in gossip tests), generate 5 more.

1. We explicitly assert what state we're coming from, to make transitions
clearer.
2. Every transition has a state, even between owners while waiting for HSM.
3. Explictly step though getting the HSM signature on the funding tx
before starting channeld, rather than doing it in parallel: makes
states clearer.

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.

Under stress, the tests can mine blocks too soon, and the funding never
locks. This gives more of a chance, at least.

I couldn't actually figure out how to just dump them on error, so I
dump all the time. When running 3 lightningd + bitcoind, this separates
the logs nicely.

Mainly switching from the old include to the new include and adjusting
the actual size of the onion packet. It also moves `channel.c` to use
`struct hop_data`.
It introduces a dummy next hop in `channel.c` that will be replaced in
the next commit.
This moves all the non-legacy blackbox testing into python.

Note that this doesn't valgrind the subdaemons: that patch seems to cause
some issues in the python framework which I am still chasing.

Running long integration tests could result in `bitcoind` dropping the
connection inbetween calls, and since python-bitcoinlib does not
reconnect and/or retry, all subsequent tests would fail as well. This
patch switches to throwaway connections, each serving just one
request. It's easier than to reach into the bitcoinlib to reconnect
and reauth, but comes with some overhead, but I think it's acceptable
for the few bitcoin calls we actually perform.
By looking for 'Done loading' in the log output we should actually be
called after `SetRPCWarmupFinished` in bitcoind. Only then is it safe
to make RPC calls. This resulted in the test suite being a bit flaky.
