Saw this in Travis: technically we return from the dev_set_max_scids...
cmd after sending it to gossipd, but we should wait for it to log.
Adding an internal reply message for a dev command seems overkill.

1. If the IPv6 address was public, that changed the wireaddr and thus the ipv4 bind
would not be to a wildcard and would fail.
2. Binding two fds to the same port on both wildcard IPv4 and IPv6 succeeds; we only
fail when we try to listen, so allow error at this point.
For some reason this triggered on my digital ocean machine.

openingd calculates our reserve based on the channel amount (even if
we're funding, to keep the calculation in one place), but it wasn't
reporting it back to the master daemon. We initialized it to 0 so that
valgrind wouldn't get upset, as it's part of a structure we send over
the wire.
Have openingd report back, and also initialize it to an impossible value
as extra assurance. And remove a stray (harmless but weird) semicolon.

This adds one line with the onion and the channel_update we extract from
it. This in turn allows us to check that the channel_update in the onion is not
type prefixed, and that we patch it correctly before passing it to gossipd.
The easiest way to do this is to play with the 'wallet_tx' semantics
and have 'amount' have meaning even when 'all_funds' is set.
Note that we change the string 'Cannot afford funding transaction' to
'Cannot afford transaction' as this code is also used for withdrawls.

We were *supposed* to be waiting for the next commitment tx so we
made sure the one we broadcast was old, *but* the 'revoke_and_ack'

This needs to be done separately from the rest of the daemon since we can
otherwise not make sure that it happens before the DB is freed and we might
still need the DN, and be running in a DB transaction, for some destructors to
run.
That was the cause of the bad gossip order failures: gossipd thought our
channel was live, but the other end didn't receive message last time.
Now gossipd doesn't use fd to kill us (connectd tells master to do so), we
can implement read_peer_msg_nogossip().

This patch guts gossipd of all peer-related functionality, and hands
all the peer-related requests to channeld instead.
gossipd now gets the final announcable addresses in its init msg, since
it doesn't handle socket binding any more.
lightningd now actually starts connectd, and activates it. The init
messages for both gossipd and connectd still contain redundant fields
which need cleaning up.
There are shims to handle the fact that connectd's wire messages are
still (mostly) gossipd messages.

Gossipd combines the information if it knows it, but that's really the
job of 'listnodes'. More importantly, channeld won't have access to
this information.

I saw an error in test_gossip_weirdalias in Travis, where listnodes(nodeid)
returned *BOTH* nodes; it happened to fail because [0] was the wrong one, but
it would have passed if the order had been different.
This helper asserts that we really do only have one element, and should
catch such bugs faster.

In this test we tell l3 to disconnect on sending WIRE_CHANNEL_ANNOUNCEMENT.
This is hit by gossipd (to disconnect from l2) but *also* channeld to
disconnect from l4. That's OK, because normally by this point l4 has
sent its real channel_update.
However, the next patch introduces a delay in sending channel_updates,
meaning l4 hasn't sent it yet. If l3 doesn't reconnect to l4, we
never get the channel_update and the test which expects l1 to eventually
see both sides of the channel fails.
So we manually reconnect then. Note that we remove the redundant
'dev-no-reconnect' option from l2: it's added automatically as it
doesn't set 'may_reconnect'.

As of bitcoind 0.16.1, you can't send a single-input OP_RETURN output,

New codes: FUND_MAX_EXCEEDED, FUND_CANNOT_AFFORD, FUND_DUST_LIMIT_UNMET.
The error message "Cannot afford fee" was not exactly correct because
it would also occur if the amount requested could not be afforded. So
I changed it to the more generic "Cannot afford transaction".
Other things:
* Fixed off-by-one satoshi in fundchannel manpage.
* Changed 'arror' to 'error' because we are not pirates.
I still believe that 2 weeks is way too much, but we were promised that these
defaults would be slowly reduced to saner values as the stability increases.

When opening a number channels from a single node we could end up not waiting
for the funding tx to make it into the mempool, instead triggering on a previous

actual funding transaction makes it into the mempool and that we wait for the
depth change for that specific channel.

Because we have too many which are never used and I don't want to document
them.
1. Remove unused anchor_onchain_wait. When implemented, it should be
hardcoded to 100 or more.
2. Remove anchor_confirms_max. 10 always reasonable, and we can readd
an override option should someone need it.
3. max_htlc_expiry should be the same as locktime_max (which increases
from 3 to 5 days by default): they're both a limit on how long
funds can be locked up.
4. channel_update_interval should always be a dev option.
