We never hit the guess_feerate() path, because we turned a 0 ("can't
estimate fee") into 253.
This also revealed that we weren't initializing topo->feerate, and
that we were giving spurious updates even if we were using override-fee-rates.

Just have a "new depth" callback, and let channeld do the right thing.
This makes the channeld paths a bit more straightforward.

Tor wasn't actually working for me to connect to anything, but it worked
for 'ssh -D' testing.
Note that the resulting 'netaddr' is a bit weird, but I guess it's honest.

This is useful for the next patch, where we want to hand the unresolved
name through to the proxy.
This also addresses @Saibato's worry that we still called getaddrinfo()
(with the AI_NUMERICHOST option) even if we didn't want a lookup.

1. If we have a channel_announcement, the channel is public, otherwise
it's not. Not all channels are public, as they can be local: those
have a NULL channel_announcement.
2. If we don't have a channel_update, we know nothing about that half
of the channel, and no other fields are valid.
3. We can tell if a half channel is disabled by the flags field directly.
Note that we never send halfchannels without an update over
gossip_getchannels_reply so that marshalling/unmarshalling can be
vastly simplified.

This means it will effect connect commands too (though it's too
late to stop DNS lookups caused by commandline options).
We also warn that this is one case where we allow forcing through Tor
without a proxy set: it just means all connections will fail.

This takes the Tor service address in the same option, rather than using
a separate one. Gossipd now digests this like any other type.

Risks leakage. We could do lookup via the proxy, but that's a TODO.
There's only one occurance of getaddrinfo (and no gethostbyname), so
we add a flag to the callers.
Note: the use of --always-use-proxy suppresses *all* DNS lookups, even
those from connect commands and the command line.
FIXME: An implicit setting of use_proxy_always is done in gossipd if it
determines that we are announcing nothing but Tor addresses, but that
does *not* suppress 'connect'.
This is fixed in a later patch.

Rename tor_proxyaddrs and tor_serviceaddrs to tor_proxyaddr and tor_serviceaddr:
the 's' at the end suggests that there can be more than one.
Make them NULL or non-NULL, rather than using all-zero if unset.
Hand them the same way to gossipd; it's a bit of a hack since we don't
have optional fields, so we use a counter which is always 0 or 1.

There's no reason to do this async, and far easier to follow using normal
read/write.
The previous parsing was deeply questionable, using substring searches
only, and relying on the fact that a single non-blocking read would get
the entire response. This is changed to do (somewhat) proper parsing
using ccan/rbuf.

This is simply the code to set up the automatic hidden service, so move

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.

Someone could try to announce an internal address, and we might probe
it.
This breaks tests, so we add '--dev-allow-localhost' for our tests, so
we don't eliminate that one. Of course, now we need to skip some more
tests in non-developer mode.

If we're given a wildcard address, we can't announce it like that: we need
to try to turn it into a real address (using guess_address). Then we
use that address. As a side-effect of this cleanup, we only announce
*any* '--addr' if it's routable.
This fix means that our tests have to force '--announce-addr' because
otherwise localhost isn't routable.
This means that gossipd really controls the addresses now, and breaks
them into two arrays: what we bind to, and what we announce. That is
now what we return to the master for json_getinfo(), which prints them
as 'bindings' and 'addresses' respectively.

1. Add special option where an empty host means 'wildcard for IPv4 and/or IPv6'
which means ':1234' can be used to set only the portnum.
2. Only add this protocol wildcard if --autolisten=1 (default)
and no other addresses specified.
3. Pass it down to gossipd, so it can handle errors correctly: in most cases,
it's fatal not to be able to bind to a port, but for this case, it's OK
if we can only bind to one of IPv4/v6 (fatal iff neither).

This replacement is a little menial, but it explicitly catches all
the places where we allow a local socket. The actual implementation of
opening a AF_UNIX socket is almost hidden in the patch.
The detection of "valid address" is now more complex:
p->addr.itype != ADDR_INTERNAL_WIREADDR || p->addr.u.wireaddr.type != ADDR_TYPE_PADDING
But most places we do this, we should audit: I'm pretty sure we can't
get an invalid address any more from gossipd (they may be in db, but
we should fix that too).

Now we only bind to addresses in our wireaddrs array, we would not
autobind to local sockets if they couldn't reach google's nameserver.
That's clearly wrong: we should only not bind if there's a protocol
issue (eg. no IPv6 support).

It's become clear that our network options are insufficient, with the coming
addition of Tor and unix domain support.
Currently:
1. We always bind to local IPv4 and IPv6 sockets, unless --port=0, --offline,
or any address is specified explicitly. If they're routable, we announce.
2. --addr is used to announce, but not to control binding.
After this change:
1. --port is deprecated.
2. --addr controls what we bind to and announce.
3. --bind-addr/--announce-addr can be used to control one and not the other.
4. Unless --autolisten=0, we add local IPv4 & IPv6 port 9735 (and announce if they are routable).
5. --offline still overrides listening (though announcing is still the same).
This means we can bind to as many ports/interfaces as we want, and for
special effects we can announce different things (eg. we're sitting
behind a port forward or a proxy).
What remains to implement is semi-automatic binding: we should be able
to say '--addr=0.0.0.0:9999' and have the address resolve at bind
time, or even '--addr=0.0.0.0:0' and have the port autoresolve too
(you could determine what it was from 'lightning-cli getinfo'.

We set no_reconnect with --offline, but that doesn't work if !DEVELOPER.

Originally we were supposed to tell the HSM we had just created the directory,

No new functionality, just a continuation of my work toward completing #665.
I removed the common members of `struct withdrawal` and `struct fund_channel`
and placed them in a new `struct wallet_tx`. Then it was fairly straightforward
to reimplement the existing code in terms of `wallet_tx`.
Since I made some structural changes I wanted to get this approved before I
go any farther.
Added 'all' to fundchannel help message.
Fixes: #1445
Hacky fix, possibly. First cut at avoiding starting up onchaind and gossipd (which might make queries of chaintopology, which might start up a bitcoin-cli) before we can daemonize.
We're getting spurious closures, even on mainnet. Using --ignore-fee-limits
is dangerous; it's slightly less so to lower the minimum (which is the
usual cause of problems).
So let's halve it, but beware the floor.
This is a workaround, until we get independent feerates in the spec.

This means gossipd is live and we can tell it things, but it won't
receive incoming connections. The split also means that the main daemon
continues (eg. loading peers from db) while gossipd is loading from the store,
potentially speeding startup.

If we start accepting peer connections before we initialized some of the other
parts (mainly the chaintopology) we could end up asking for stuff that isn't

If channeld dies for some reason (eg, reconnect) and we didn't yet announce
the channel, we can miss doing so. This is unusual, because if lightningd
restarts it rearms the callback which gives us funding_locked, so it only
happens if just channel dies before sending the announcement message.
This problem applies to both temporary announcement (for gossipd) and
the real one. For the temporary one, simply re-send on startup, and
remote the error msg gossipd gives if it sees a second one. For the
real one, we need a flag to tell us the depth is sufficient; the peer
will ignore re-sends anyway.
