In particular, the main daemon and subdaemons share the backtrace code,
with hooks for logging.
The daemon hook inserts the io_poll override, which means we no longer
need io_debug.[ch]. Though most daemons don't need it, they still link
against ccan/io, so it's harmess (suggested by @ZmnSCPxj).
This was tested manually to make sure we get backtraces still.

Several daemons (onchaind, hsm) want to use the status messages, but
don't communicate with peers. The coming changes made them drag in
more code they didn't need, so instead we have a different
non-overlapping type.
We combine the status_received_errmsg and status_sent_errmsg
into a single status_peer_error, with the presence or not of the
'error_for_them' field indicating direction.
We also rename status_fatal_connection_lost() to
peer_failed_connection_lost() to fit in.

Now we have wirestring, this is much more natural. And with the
24M length limit, we needn't be so concerned about dumping 64k peer
messages in hex.

We need to override two methods: the io error (tell gossipd to
disable), and send reply (enqueue, don't write direclty).

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.

The #389 introduced some changes that conflicted with
9de3827199 so this ports those changes
into #389 and fixes the `master` branch again.
Lesson learned: always rebase a PR before merging.

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.
