This is a rebased and combined patch for Tor support. It is extensively
reworked in the following patches, but the basis remains Saibato's work,
so it seemed fairest to begin with this.
Minor changes:
1. Use --announce-addr instead of --tor-external.
2. I also reverted some whitespace and unrelated changes from the patch.
3. Removed unnecessary ';' after } in functions.

This means that openingd and closingd now forward our gossip. But the real
reason we want to do this is that it gives an easy way for gossipd to kill
any active daemon, by closing its fd: previously closingd and openingd didn't
read the fd, so tended not to notice.

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.

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).

To avoid everything pulling in HTLCs stuff to the opening daemon, we
split the channel and commit_tx routines into initial_channel and
initial_commit_tx (no HTLC support) and move full HTLC supporting versions
into channeld.
