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.

This is just copying most of gossipd/gossip.c into connectd/connect.c.
It shares the same wire format as gossipd during transition, and changes
are deliberately minimal.
It also has an additional message 'connect_reconnected' which it sends
to the master daemon to tell it to kill a peer; gossipd relied on
closing the gossipfd to do this, but connectd doesn't maintain an fd
with remote peers.

All gossipd needs from common/tor is do_we_use_tor_addr(), so move
that and the rest of the tor-specific handshake code into gossip/tor.c
