The wire protocol uses this, in the assumption that we'll never see feerates
in excess of 4294967 satoshi per kiloweight.
So let's use that consistently internally as well.

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.

We currently scan through HTLCs: this isn't enough if we've only got a
feechange in the commitment, so use a flag (but keep both for now for
debugging).

All the callers need to pass it in: currently channeld and openingd just
fake it by copying the payment point.

We were sending the announcement_signatures as soon as we locally
locked and got the announcement_depth, this doesn't make the channel
usable any sooner and forces the other side to stash the
signature. This defers the announcement_signature until the channel
really is usable.
This is done by adding an additional check for the remote locked
message and adding a trigger on remote lock.

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.

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.

In this case, it was a gossip message half-sent, when we asked the peer
to be released. Fix the problem in general by making send_peer_with_fds()
wait until after the next packet.

The problem occurs here on release, but could be on any place where we hand
a peer over when using ccan/io. Note the other case (channel.c).

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

In particular, the main daemon needs to pass it about (marshal/unmarshal)

We were sending a channeld message to onchaind, which was v. confusing
due to overlap. We make all the numbers distinct, which means we can
also add an assert() that it's valid for that daemon, which catches
such errors immediately.

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).

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.

The logic of dispatching the announcement_signatures message was
distributed over several places and daemons. This aims to simplify it
by moving it all into `channeld`, making peer_control only report
announcement depth to `channeld`, which then takes care of the
rest. We also do not reuse the funding_locked tx watcher since it is
easier to just fire off a new watcher with the specific purpose of
waiting for the announcement_depth.

jl777 reported a crash when we try to pay past reserve. Fix that (and

In test_lightning.py I had to make non-async path for sendpay() non-threaded
