Since we include the tail of the version in the default aliasname with
DEVELOPER, we want to see more of it.

We can create the hsm file from python directly; that works even if we
don't have DEVELOPER set, and is simpler.
We add a test that the aliases are correct.

Originally we were supposed to tell the HSM we had just created the directory,
otherwise it wouldn't create a new seed. But we modified it to check if
there was a seed file anyway: just move that logic into a branch of hsmd.

We had quite a few users running into issues because the `--dev-xyz` options and
`dev-xyz` RPC calls were available. Before a release we should make sure that
the default compilation flags are safe.

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
ready yet (blockchain head for example).

I would have liked to make it a tal object, then we'd catch most
things with our memleak detection. However, sqlite3 doesn't seem to
allow allocator overrides.

This is the cause of 'sqlite3_close: unable to close due to unfinalized statements or unfinished backups' with the --daemon option.

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.

When a connect fails, if it's an important peer, we set a timer. If
we have a manual connect command, this means we do this again, leading
to another timer.
For a manual command, free any existing timer; the normal fail logic
will start another if necessary.

At least say whether we failed to connect at all, or failed cryptographic
handshake, or failed reading/writing init messages.
The errno can be "Operation now in progress" if the other end closes the
socket on us: this happens when we handshake with the wrong key and it
hangs up on us. Fixing this would require work on ccan/io though.

When we get a reconnection, kill the current remote peer, and wait for the
master to tell us it's dead. Then we hand it the new peer.
Previously, we would end up with gossipd holding multiple peers, and
the logging was really hard to interpret; I'm not completely convinced
that we did the right thing when one terminated, either.
Note that this now means we can have peers with neither ->local nor ->remote
populated, so we check that more carefully.

Currently we intuit it from the fd being closed, but that may happen out
of order with when the master thinks it's dead.
So now if the gossip fd closes we just ignore it, and we'll get a
notification from the master when the peer is disconnected.
The notification is slightly ugly in that we have to disable it for
a channel when we manually hand the channel back to gossipd.
Note: as stands, this is racy with reconnects. See the next patch.

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.

(This was sitting in my gossip-enchancement patch queue, but it simplifies
this set too, so I moved it here).
In 94711969f we added an explicit gossip_index so when gossipd gets
peers back from other daemons, it knows what gossip it has sent (since
gossipd can send gossip after the other daemon is already complete).
This solution is insufficient for the more general case where gossipd
wants to send other messages reliably, so replace it with the other
solution: have gossipd drain the "gossip fd" which the daemon returns.
This turns out to be quite simple, and is probably how I should have
done it originally :(
