It's generally clearer to have simple hardcoded numbers with an
#if DEVELOPER around it, than apparent variables which aren't, really.
Interestingly, our pruning test was always kinda broken: we have to pass
two cycles, since l2 will refresh the channel once to avoid pruning.
Do the more obvious thing, and cut the network in half and check that
l1 and l3 time out.

Rather than reaching into data structures, let them register their own
callbacks. This avoids us having to expose "memleak_remove_xxx"
functions, and call them manually.
Under the hood, this is done by having a specially-named tal child of
the thing we want to assist, containing the callback.

Keeping the uintmap ordering all the broadcastable messages is expensive:
130MB for the million-channels project. But now we delete obsolete entries
from the store, we can have the per-peer daemons simply read that sequentially
and stream the gossip itself.
This is the most primitive version, where all gossip is streamed;
successive patches will bring back proper handling of timestamp filtering
and initial_routing_sync.
We add a gossip_state field to track what's happening with our gossip
streaming: it's initialized in gossipd, and currently always set, but
once we handle timestamps the per-peer daemon may do it when the first
filter is sent.

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.

Christian and I both unwittingly used it in form:
*tal_arr_expand(&x) = tal(x, ...)
Since '=' isn't a sequence point, the compiler can (and does!) cache
the value of x, handing it to tal *after* tal_arr_expand() moves it
due to tal_resize().
The new version is somewhat less convenient to use, but doesn't have
this problem, since the assignment is always evaluated after the
resize.

It's more natural than using a zero-secret when something goes wrong.
Also note that the HSM will actually kill the connection if the ECDH
fails, which is fortunately statistically unlikely.

We need several notleak() annotations here:
1. The temporary structure which is handed to retry_peer_connected().
It's waiting for the master to respond to our connect_reconnected
message.
2. We don't keep a pointer to the io_conn for a peer, so we need to
mark those as not being a leak.

It means an extra allocation at startup, but it means we can hide the definition,

When the wrong key is used, the remote end simply hangs up.
We used to get a random errno, which tends to be "Operation now in progress."
Now it's defined to be 0, detect and provide a better error.

I split the peer_connected() function into the peer_reconnected(),
which is basically an entire separate path from the rest of
peer_connected().
Also, removed unused TAKEN annotation from `id` parameter. Nobody actually
hands us take() there, and just as well, since we don't take it!

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.

We do this a lot, and had boutique helpers in various places. So add
a more generic one; for convenience it returns a pointer to the new
end element.
I prefer the name tal_arr_expand to tal_arr_append, since it's up to
the caller to populate the new array entry.

We sweep looking for pointers to tal objects; we don't look for pointers
inside them. Thus lists only work transparently if they're at the head
