16e9ba0361 connectd: fix confusing names.
The message from lightningd simply acknowleges that we are allowed to
discard the peer (because no subdaemons are talking to it anymore).
This difference becomes more stark once connectd holds on to idle
peers.

eb203bf71e lightningd: clean up connect code.
1. The notification should be called every time.
2. channel can never be NULL, since it's tested above.

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.

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.

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.

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`.

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.

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.

e99b11565c pyln: Change the default argument to exclude in pay
We must use `None` for default arguments since otherwise they aren't
filtered out when serializing the request. In addition default
arguments to functions are initialized once and, if mutable, could
persist internal changes across function calls.

f72a08c802 websocketd: fix random failures by blocking stdin reads
Example request that is dying:

NEW REQUEST! lightning_websocketd:main [1955685] <-- bad request from safari

   read 507
   write_all 1
-> websocket_to_lightningd
-> read_payload_header
   read 2
   read_all 1
   read -11      <--- This tried to read a part of the header, is this -EAGAIN?
   read_all 0         should we be blocking on these reads?
   *dies*

Fixes #5089

Changelog-Fixed: `experimental-websocket` intermittent read errors fixed

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

Update tor install to represent current systemd syntax for enabling and starting a new system service
Corrected a typo. After tor is installed to refresh /etc/tor/torrc config changes the command should be 'sudo systemctl restart tor' not 'sudo systemctl start tor'
