We always hand in "NULL" (which means use tal_len on the msg), except
for two places which do that manually for no good reason.

DEBUG:root:lightningd(16333): 2018-02-08T02:12:21.158Z lightningd(8262): lightning_openingd(0382ce59ebf18be7d84677c2e35f23294b9992ceca95491fcf8a56c6cb2d9de199): Failed hdr decrypt with rn=2
We only hand off the peer if we've not started writing, but that was
insufficient: we increment the sn twice on encrypting packet, so there's
a window before we've actually started writing where this is now
wrong.
The simplest fix is only to hand off from master when we've just written,
and have the read-packet path simply wake the write-packet path.

We get intermittant failure: WIRE_UNKNOWN_NEXT_PEER (First peer not ready)
because CHANNELD_NORMAL and actually telling gossipd that the channel
is available are distinct things: we need both.
(For test_closing_different_fees, we were testing CHANNELD_NORMAL on
the peer, not on l1, too).
But we may also directly send the announcement sigs if the height is
sufficient, so the simplest is to unify the messages.

These are now logically arrays of pointers. This is much more natural,
and gets rid of the horrible utxo array converters.

We need to make sure all the updates are known to gossip. Since
one is the local update, we change that message to look the same.

This is done it two parts, since we have to ask the main daemon to do
the lookup for us.
If this becomes a bottleneck, we can have a separate daemon, or even
an RPC pipe to bitcoind ourselves.

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.

It's just a sha256_double, but importantly when we convert it to a
string (in type_to_string, which is used in logging) we use
bitcoin_blkid_to_hex() so it's reversed as people expect.

This adds the channel from us to the remote node and activates it with
our local parameters.

Couldn't find a good place to put these messages, we probably want to
do the same capability based request routing that we did for the HSM,
but for now this just defines the message in the master messages file.

When gossipd sends a message, have a gossip_index. When it gets back a
peer, the current gossip_index is included, so it can know exactly where
it's up to.
Most of this is mechanical plumbing through openingd, channeld and closingd,
even though openingd and closingd don't (currently) read gossip, so their
gossip_index will be unchanged.
