We re-use the value for reasonable_depth given by the master, and we
tell it when our timeout transactions reach that depth.

In the next test, we wait for multiple 'sendrawtx exit 0' which
doesn't work because we use a set not a list, and the current code
would match multiple against the same thing. The result was we didn't
wait for the final sendrawtransaction, and occasionally had test
failures as a result.

When we sent out an HTLC-Timeout or HTLC-Success tx, we need to spend
it after the timeout so it's safely in our wallet.
We generalize the tx_type OUR_UNILATERAL_TO_US_RETURN_TO_WALLET to
OUR_DELAYED_RETURN_TO_WALLET, since we use it for HTLC transactions too.

When we see an offered HTLC onchain, we need to use the preimage if we
know it. So we dump all the known HTLC preimages at startup, and send
new ones as we discover them.
This doesn't cover preimages we know because we're the final
recipient; that can happen if an HTLC hasn't been irrevocably
committed yet. We'll do that in a followup patch.

For non-delayed HTLC success spends, we have a similar pattern ("<sig>
<preimage> <wscript>") so a we want to use the same function.
The other routines don't say "witness" in them, and should.

If the HSM is slow it might happen that the timestamp has changed the
second time we come around, so we generate the timestamp externally
and pass it in so we're sure it won't change between calls.

lightningd can crash on shutdown if it's in the middle of getchaintips;
we free the conn, the finished callback is called (process_chaintips),
and it reports that it received an empty result.
The simplest fix is to set a flag in the struct bitcoind destructor,
and avoid the callback.

Either when it exits with a signal, or sends an error status message.
Then we make test_lightningd.py use it.

We simply kill lightningd; we should stop it properly and have a timeout
to kill it if that fails. However, that's beyond my python skills :(
So we just look for crash.log. Unfortunately, we usually kill
lightningd before it's finished writing it. So we look for it and
don't kill lightningd, just wait in this case.

This change is really to allow us to have a --dev-fail-on-subdaemon-fail option
so we can handle failures from subdaemons generically.
It also neatens handling so we can have an explicit callback for "peer
did something wrong" (which matters if we want to close the channel in
that case).

1. Remove reference to old $(LIGHTNINGD_OLD_LIB_OBJS) var (in handshaked too).
2. Make check depend directly on unit tests, insteadof weird lightningd/tests
variable.
3. check-source-bolt and check-whitespace are automatic for $(ALL_TEST_PROGRAMS)
so we don't need them here.

This is the step where we broadcast the transaction to the network and
a nice place to extract the change from the transaction.

We got a commit_sig from the peer while waiting for the master to
reply to acknowledge the commitsig we want to send
(handle_sending_commitsig_reply).
The fix is to go always talk to the master synchronous, and not try to
process anything but messages from the master daemon. This avoids the
whole class of problems.
There's a fairly simple way to do this, as ccan/io lets you override
its poll call: we process any outstanding master requests there, or
add the master fd to the pollfds array.

It's no longer used and we definitely do not want to run with an
outdated or future db, so we'll terminate if we can't upgrade or
the version is newer than what we understand.

For the permfail tests the sendpay call is supposed to fail, so this
was printing stacktraces upon success. Running in futures captures any
thrown exceptions and rethrows them when calling `result()`, in our
case we just ignore them.

So far we were always using the deadline in the announcements, that's
obviously not good, so this introduces the parameter as per spec.
