In particular, handle pings. The rest is modelled on the channeld one,
but annoyingly different enough that it's hard to share code without
significant work.

Our handling of SIGPIPE was incoherent and inconsistent, and we had much
cut & paste between the daemons. They should *ALL* ignore SIGPIPE, and
much of the rest of the boilerplate can be shared, so should be.

We create a temporary tx which is a child of the real tx, for simplicity of
marshalling. That's OK.

In particular, the main daemon needs to pass it about (marshal/unmarshal)
but it won't need to actually use it after the next patch.

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).
