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.
Fixes: #266

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
a whole class of related bugs) and add tests.
In test_lightning.py I had to make non-async path for sendpay() non-threaded
to get the exception passed through for testing.
Closes: #236
