Either because lightningd tells us it wants to talk, or because the peer
says something about a channel.
We also introduce a behavior change: we disconnect after a failed open.
We might want to modify this later, but we it's a side-effect of openingd
not holding onto idle connections.

The message from lightningd simply acknowleges that we are allowed to
discard the peer (because no subdaemons are talking to it anymore).
This difference becomes more stark once connectd holds on to idle
peers.

We always added to both arrays, might as well just keep one.
We make mayfail an explicit flag, rather than relying on the presence
of errstr, which is never NULL now.

Gossipd now simply gets told by channeld when peers arrive or leave.
(it only needs to know for the seeker).

We want to stream gossip through this, but currently connectd treats the
fd as synchronous. While we work on getting rid of that, it's easiest to
have two fds.

We would lose packets sometimes due to this previously, but it
doesn't happen over localhost so our tests didn't notice. However,
now we have connectd being sole thing talking to peers, we can do
a more elegant shutdown, which should fix closing.

Changelog-Fixed: Protocol: Always flush sockets to increase chance that final message get to peer (esp. error packets).
dev_blackhole_fd was a hack, and doesn't work well now we are async
(it worked for sync comms in per-peer daemons, but now we could sneak
through a read before we get to the next write).
So, make explicit flags and use them. This is much easier now we
have all peer comms in one place.

We actually intercept the gossip_timestamp_filter, so the gossip_store
mechanism inside the per-peer daemon never kicks off for normal connections.
The gossipwith tool doesn't set OPT_GOSSIP_QUERIES, so it gets both, but
that only effects one place.

@thestick613 noticed that since tor version below 0.3.2.2-alpha
will not support V3 ed25519 address formats, the error handling
is not that helpful in the error message from cli.
So now we add an hint.

It's almost always "their_features" and "our_features" respectively, so
make those names clear.

This will help with the next patch, where we wean off using a global
for features: connectd.c has access to the feature bits.
Since connectd might now want to send a message, it needs the crypto_state
non-const, which makes this less trivial than it would otherwise be.

This is mainly an internal-only change, especially since we don't
offer any globalfeatures.
However, LND (as of next release) will offer global features, and also
expect option_static_remotekey to be a *global* feature. So we send
our (merged) feature bitset as both global and local in init, and fold
those bitsets together when we get an init msg.

We used to generate this in the caller, then save it in case we needed
to retry. We're about to change the message we send to lightningd, so
we'll need to regenerate it every time; just hand all the extra args
into peer_connected() and we can generate the `connect_peer_connected`
msg there.

I tried to just do gossipd, but it was uncontainable, so this ended up being
a complete sweep.
We didn't get much space saving in gossipd, even though we should save
24 bytes per node.

connectd is the only user of the cryptomsg async APIs; better to
open-code it here. We need to expose a little from cryptomsg(),
but we remove the 'struct peer' entirely from connectd.
One trick is that we still need to defer telling lightningd when a
peer reconnects (until it tells us the old one is disconnected). So
now we generate the message for lightningd and send it once we're woken.

@renepickhardt: why is it actually lightningd.c with a d but hsm.c without d ?
And delete unused gossipd/gossip.h.
