6115ed02e8 subdaemons: don't stream gossip_store at all.
We now let gossipd do it.

This also means there's nothing left in 'struct per_peer_state' to
send across the wire (the fds are sent separately), so that gets
removed from wire messages too.

029d65cf2e connectd: serve gossip_store file for the peer.
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.

e37a638c0c connectd: do nagle by packet type.
channeld can't do it any more: it's using local sockets.  Connectd
can do it, and simply does it by type.

Amazingly, on my machine the timing change *always* caused
test_channel_receivable() to fail, due to a latent race.

Includes feedback from @cdecker.

e683649004 connectd: maintain connection with peer, shuffle data.
Instead of passing the incoming socket to lightningd for the
subdaemon, create a new one and simply shuffle data between them,
keeping connectd in the loop.

For the moment, we don't decrypt at all, just shuffle.  This means our
buffer code is kind of a hack, but that goes away once we start
actually decrypting and understanding message boundaries.

This implementation is naive: it closes the socket to the local daemon
as soon as the peer closes the socket to us.  This is fixed in a
successive patch series (along with many other similar issues).

35eaaf8e63 cli: change the redefine logic to read from the stdin
Procedure redefinition is a very cool feature but when other libraries redefine the same function can be very tricky to avoid compilation error.

This PR proposed a change of logic and use a customizzation function definition to read from the stdin, so we can avoid future error at compile time.

However, we could be check also the os or compiler that cause the error and redefine the missing function.

Changelog-None: Fixed compilation error due redefinition procedure.

425a7af512 common/coin_mvt: clean up API a little.
1. tal_strndup(.., str, strlen(str)) == tal_strdup()
2. tal_strdup also takes(), so document that.
3. Avoid passing 'struct sha256' on the stack: use ptr.
4. Generally, structures shouldn't keep pointers to things they don't own.
   In this case, mvt->node_id.
5. Make payment_hash a pointer, since NULL is more natural than an all-zero
   hash.

And add NON_NULL_ARGS() to the functions; it's cumbersome, but make it
fairly clear what params are optional.

0aad222c2d gossipd: rewrite update generation, remove local_chan.
local_chan was mainly around so we could "soft" disable channels (and
really disable them once we used the channel_update in an error
message).

Instead we introduce the idea of a "deferred_update": it's either
deferred indefinitely (a peer goes offline, if we need to send it in
an error we'll apply it immediatly), or simply delayed to avoid
spamming everyone.

The resulting rewrite is much clearer, IMHO.

8225a9decf coin_mvt: log events for pushes/lease_fees for leased channels
We need to stash/save the amount of the lease fees on a leased channel,
we do this by re-using the 'push' amount field on channel (which is
technically correct, since we're essentially pushing the fee amount to
the peer).

Also updates a bit of how the pushes are accounted for (pushed to now
has an event; their channel will open at zero but then they'll
immediately register a push event).

Leases fees are treated exactly the same as pushes, except labeled
differently.

Required adding a 'lease_fee' field to the inflights so we keep track of
the fee for the lease until the open happens.
