Rusty Russell 9bbb32433e connectd: make sure we do IO logging on final_msg output.
This happens when we send a warning or lightningd tells us to send a
final message then close.  Normally io logging is done by the
subdaemon that creates it, but this is a special case.

Rusty Russell b99c04e605 lightningd: add explicit "connected" flag.
We currently intuit this by whether there's a subdaemon owning it.
But we're about to change the rules and allow connectd to hold idle
connections, so we need an explicit flag.

Christian Decker 722f2911df py: Disentangle pyln dependencies
Turns out that the pyln-proto dependency in the bolt packages is only
needed for testing, not for production. Making it a dev-dependency
means it isn't considered in resolution anymore.

Since the bolt, testing and client packages are to be used outside
from the project we can't use relative dependencies either, so make
then dependent on the version on PyPI. This also means we had to push
a couple of updated to PyPI.

Rusty Russell 66e264d6b3 lightningd: new setchannel command.
Based on setchannelfee, but expanded to allow setting max htlc amount (and others
in future?).

The main differences:
1. It doesn't change values which are not specified (that would be hard to
   add fields to!)
2. It says exactly what all values are in any potentially changed channels.

Changelog-Added: JSON-RPC: new `setchannel` command generalizes `setchannelfee`.

Rusty Russell 65be18d355 memleak: handle libwally allocations better.
Things allocated by libwally all get the tal_name "wally_tal",
which cost me a few hours trying to find a leak.

In the case where we're making one of the allocations the parent
of the others (e.g. a wally_psbt), we can do better: supply a name
for the tal_wally_end().

So I add a new tal_wally_end_onto() which does the standard
tal_steal() trick, and also changes the (typechecked!) name.

Christian Decker 487b5e6169 msggen: Add meta file to keep the field numbers stable
We are inferring the field numbers on the fly, which isn't really
compatible with the way GRPC field numbers work, i.e., they must be
stable while the IDL file evolves. So far when a field was added in
the middle of a struct or removed all subsequent fields would get
renumbered, essentially breaking any client that was using the old
scheme.

We now add a meta file `.msggen.json` that keeps track of the numbers
assigned so far, so they can be reused, and new ones can be generated
not to conflict with existing ones. This file is intentionally kept
generic, so other generators can add more information that has to be
managed across runs.

Goofy af tor.md systemd syntax update (#5059)
Update TOR.md

Michael Schmoock 67fdc6f8ad gossipd: send updated node_annoucement remote_addr
This is the cheapest algo I came up with that simply checks that the
same `remote_addr` has been report by two different peers. Can be
improved in many ways:

 - Check by connecting to a radonm peers in the network
 - Check for more than two confirmations or a certain fraction
 - ...

Changelog-Added: Send updated node_annoucement when two peers report the same remote_addr.

Michael Schmoock b930b8c548 wireaddr: adds wireaddr_eq_without_port and wireaddr_cmp_type
Adds wireaddr_eq_without_port so it can be used later.
Moves wireaddr_cmp_type from connectd.c to this file, so it can be reused later.

Michael Schmoock f1981461ef connectd: ignore private remote_addr on non-DEVELOPER builds
When compiled without DEVELOPER this will now filter out `remote_addr` that
come from localhost. The testcase checks for DEVELOPER to test for correct
function of `remote_addr`.

Also, I renamed "test_connect" to "test_connect_basic" so it can be started
without all the other tests in that file that start with "test_connect..."
