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

Turns out that unnecessary: all callers can access the feature_set,
so make it much more like a normal primitive.

The `init_featurebits` are computed at startup, and then cached
indefinitely. They are then used whenever a new `init` handshake is performed.
We could add a new message to push updates to `connectd` whenever a plugin is
added or removed, but that's up for discussion.
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.
