Rusty Russell cafa1a8c65 db: correctly migrate forwards for closed incoming channels.
We have to allow them (as otherwise `fees_collected_msat` in getinfo breaks),
but it means that actually, in_htlc_id might be missing in listforwards
(also, out_htlc_id might be missing, which we didn't catch before).

Rusty Russell 6e86fa9220 lightningd: figure out optimal channel *before* forward_htlc hook.
Otherwise what the hook sees is actually a lie, and if it sets it
we might override it.

The side effect is that we add an explicit "forward_to" field, and
allow hooks to override it.  This lets a *hook* control channel
choice explicitly.

Changelod-Added: Plugins: `htlc_accepted_hook` return can specify what channel to forward htlc to.

Michael Schmoock 532544ce4f gossipd: rename remote_addr to discovered_ip within gossipd
This is cleaner because, the `remote_addr` and `discovered_ip` are
related but two different things.

Within connectd and lightningd we use the peers `remote_addr` feature
to validate (and guess a port) to be used for IP discovery.

Also when a peer reports us a `remote_addr`, this is given to the plugin API
via the `peer_connected` hook. The network port here is not modified for
godd reason! This can be used i.e. to detect if we are behind a NAT.

But once lightningd figures enough peers report the same `remote_addr`,
it sets the port to the selected network and tells gossipd to use that for
`node_announcement` updates.

Hence, within gossipd, there is no (should not be) `remote_addr`.

Rusty Russell e853cdc3ff db: fix sqlite3 code which manipulates columns.
Because it used internal routines, it didn't pass operations through the
db hook!  So make it use the generic routines, with the twist that they
are not translated.

And when we use this in a migration hook, we're actually in a
transaction.

This, in turn, introduces an issue: we need to be outside a transaction
to "PRAGMA foreign_keys = OFF", but completing the transaction when
there is a db hook actually enters the io loop, freeing the tmpctx!

Rusty Russell a3c4908f4a lightningd: don't explicitly tell connectd to disconnect, have it do it on sending error/warning.
Connectd already does this when we *receive* an error or warning, but
now do it on send.  This causes some slight behavior change: we don't
disconnect when we close a channel, for example (our behaviour here
has been inconsistent across versions, depending on the code).

When connectd is told to disconnect, it now does so immediately, and
doesn't wait for subds to drain etc.  That simplifies the manual
disconnect case, which now cleans up as it would from any other
disconnection when connectd says it's disconnected.

This allows us to detect when lightningd hasn't seen our latest

1. lightningd says to connect a subd.
2. connectd disconnects and reconnects.
3. connectd reads message, connects subd.
4. lightningd reads disconnect and reconnect, sends msg to connect to subd again.
5. connectd asserts because subd is alreacy connected.

This way connectd can tell if lightningd is talking about the previous
connection, and ignoere it.

Rusty Russell 41b379ed89 lightningd: hand fds to connectd, not receive them from connectd.
Before this patch:
1. connectd says it's connected (peer_connected)
2. we tell connectd we want to talk about each channel (peer_make_active)
3. connectd gives us an fd for each channel, and we connect it to a subd (peer_active)
4. OR, connectd says it sent something about a channel we didn't tell it about, with an fd (peer_active)

Now:
1. connectd says it's connected (peer_connected)
2. we start all appropriate subds and tell connectd to what channels/fds (peer_connect_subd).
3. if connectd says it sent something about a channel we didn't tell it about, we either tell
   it to hang up (peer_final_msg), or connect a new opening daemon (peer_connect_subd).

This is the minimal-size patch, which is why we create socket pairs in
so many places to use the existing functions.  Many cleanups are
possible, since the new flow is so simple.

Rusty Russell eff53495db lightningd: make "is peer connected" a tristate.
First, connectd tells us the peer has connected, and we call the connected hook,
and if it says it's fine, we are actually connected and we fire off notifications.

Of course, we could be disconnected while in the connected hook, and that would
mean we tell people about a connection which is no longer current.

Make this clear with a tristate: if we're not marked disconnected by
the time the hooks finish, we're good.  It also gives us a cleaner
"connect" command return when we connected but disconnected before
processing.
