xxx_msat.
2. json_add_amount_sats_deprecated: We were using it wrong, so deprecate
the old field and create a new one which does end in _msat.
3. json_add_sats: we were using it to hand sats as a JSON parameter to an

We do this (send warnings) in almost all cases anyway, so mainly this
is a textual update, but there are some changes:
1. Send ERROR not WARNING if they send a malformed commitment secret.
2. Send WARNING not ERROR if they get the shutdown_scriptpubkey wrong (vs upfront)
3. Send WARNING not ERROR if they send a bad shutdown_scriptpubkey (e.g. p2pkh in future)
4. Rename some vars 'err' to 'warn' to make it clear we send a warning.

This is generally verboten now, since there can be multiple. There are a

Changelog-Changed: JSON-RPC: `close` by peer id will fail if there is more than one live channel (use `channel_id` or `short_channel_id` as id arg).
Generally this means converting a lazy "peer_active_channel(peer)" call
into an explicit iteration.
1. notify_feerate_change: call all channels (ignores non-active ones anyway).
2. peer_get_owning_subd remove unused function.
3. peer_connected hook: don't save channel, do lookup and iterate channels.
4. In json_setchannelfee "all" remove useless call to peer_active_channel
since we check state anyway, and iterate.

Either because lightningd tells us it wants to talk, or because the peer

openingd currently holds the connection to idle peers, but we're about
to change that: it will only look after peers which are actively
opening a connection. We can start this process by disconnecting
whenever we have a negotiation failure.
We could stay connected if we wanted to, but that would be up to
connectd to decide. Right now it's easier if we disconnect from any
idle peer once it's been active.

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..."
For now hooks are treated identically to rpcmethods, with the
exception of not being returned in the `getmanifest` call. Later on we
can add typed handlers as well.
Having a list of very targeted suppressions allows us to still run the
majority of tests with valgrind checking, and not fail when Rust does
some trickery. This is for example the case with `std::sync::Once`
which uses `num_procs` calling out to the cgroups subsystem, sometimes
with a null path.

These tests have proven to be:
a) very expensive, as they spin up many nodes, and perform long setup
b) are not testing anything specific, they just fuzz functionality
that is already tested otherwise
c) have not helped pinpoint any issues in living memory
d) are very flaky, making for really bad signal-to-noise, so much
that devs usually just restart without even looking at the logs
e) even if we were to look at the logs, we'd be unable to reproduce
due to the inherent randomness involved in these tests
f) are really noisy neighbors, causing other tests to flake as well,
further muddying the water
All in all, these tests are a waste of time, and source of
frustration.

We were relying on the fee update to create an additional tx. That's
ugly; do an actual payment and make sure we definitely complete a new
tx by waiting for that *then* both revoke_and_ack.

We actually intercept the gossip_timestamp_filter, so the gossip_store

Fire off a snapshot of current account balances (node wallet + every
'active' channel) after we've caught up to the chain tip for the *first*
time (in other words, on start).
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.
If we initialized the payment, the fees are the entire fee-chain
(final hop amount - starting hop amount)
If it's a payment we routed, the fees are the diff between the
inbound htlc and the outbound (net gain by this routing)
Added to database so data persists nicely.
We record the amount of fees collected for a routed payment. For
simplicity's sake on the data agg side, we record the fee payment on
*BOTH* the incoming htlc and the outgoing htlc. Note that this results
in double counting if you add up the fees from both an in-routed and
out-routed payment.
Get rid of the 'movement_idx', since we replay events now.
Since we're removing a field from the 'coin_movement' event emission, we
bump the version type.
Changelog-Updated: `coin_movements` events have been revamped and are now on version 2.
test_onchain_dust_out restarts a node, which produces duplicate events.
this is expected, but we need to de-duplicate the events stream to get
accurate results
The old model of coin movements attempted to compute fees etc and log
amounts, not utxos. This is not as robust, as multi-party opens and dual
funded channels make it hard to account for fees etc correctly.
Instead, we move towards a 'utxo' view of the onchain events. Every
event is either the creation or 'destruction' of a utxo. For cases where
the value of the utxo is not (fully) debited/credited to our account, we
also record the output_value. E.g. channel closings spend a utxo who's
entire value we may not own.
Since we're now tracking UTXOs onchain, we can now do more complex
assertions about the onchain footprint of them. The integration tests
have been updated to now use more 'chain aware' assertions about the
ending state.

The idea is to have different default ports for different networks.
Current default port is `9735` for everything. Let's use it for
the mainnet and reuse the difference added to the default port
from `rpc_port` values in `bitcoin/chainstate.c`.
Testnet would be `19735` (adding rpc_port - 8332 = `10000`).
Signet would be `39735` (adding rpc_port - 8332 = `30000`).
Regtest would be `19846` (adding rpc_port - 8332 = `10111`).
With Vincenzo's kind pair-programming help over tmate.
Two other commits were squashed into this one so that bisecting
never ends up in half-baked state:
1. chainparams: Fix regtest default rpc_port
bitcoind -help says this:
-rpcport=<port>
Listen for JSON-RPC connections on <port> (default: 8332, testnet:
18332, signet: 38332, regtest: 18443)
2. test_gossip: Default port for regtest
hex: 2607 is now .... (could be 4d86 but Elements uses another port)
dec: 9735 is now any port (could be 19846 ^^ but now is for any port)
The lines which were binding to default port were removed as the
default port is different on each network.
NOTE: Remember not to modify gossip_store tests which loads everything raw
including the checksums.
Changelog-Changed: If the port is unspecified, the default port is chosen according to used network similarly to Bitcoin Core.
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).
config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

Now we test the more specific `Channel forgotten before proper close.`, which is good!
BTW, this test was added recently in PR #4599.
It runs 6 nodes: under valgrind this ends up consuming 5.3 GB RSS. By
stopping nodes between, we peak about 1G RSS.
Measured using:

(Which measures my other processes as well, but that's only about 100M).

Fails liquid-regtest otherwise; liquid tends to hit the dust limit
earlier than non-liquid tx, and MPP exacerbates this by divvying up
payments into dusty bits then attempting to shove them through the same
channel, hitting the dust max. The MPP then fails as not all the parts
were able to arrive at their destination.
Let's make this a softer launch by just warning on the channel til the
feerates go back down.
You can also 'fix' this by upping your dust limit with
the `max-dust-htlc-exposure-msat` config.
