If rune contains invalid UTF-8, offers (which implements decode) would
produce JSON with invalid UTF-8, which causes lightningd to complain
and kill it, and then die because it's an important plugin.
So don't decode invalid UTF-8!

Some tests need to inspect it, but most don't, and I suspect I'm missing some
error messages due to this.

The error routine returns a string literal in this case, which we can't take().

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 is a bit weird since it lives in the offers plugin, but it works
well. This should make runes much more approachable for people!

Changelog-Added: Plugins: `commando` a new builtin plugin to send/recv peer commands over the lightning network, using runes.
Previously we wouldn't notify when a channel moves into state
"CHANNELD_AWAITING_LOCKIN", as this is the original state (so there's
no movement btw states). This meant that it's impossible to track when a
channel's commitment txs have been exchanged and we're waiting for
onchain confirmation.
It's useful to have notice of this initialization though, all in one
place so that the `channel_state_changed` notification can successfully
track the entire lifecycle of a channel, from inception to close.
Note that for v2 "dual-funded" channels, we already notify at the same place, at
"DUALOPEND_AWAITING_LOCKIN" (the initial state for a dualopend channel
is "DUALOPEND_OPEN_INIT" -- this is the only state we don't get notified
at now...)
Changelog-Added: Plugins: `channel_state_changed` now triggers for a v1 channel's initial "CHANNELD_AWAITING_LOCKIN" state transition (from prior state "unknown")
We were waiting for the start to timeout waiting for the "public key"
message. Instead, start manually.
Before, this took (with TIMEOUT=30) 97 seconds, after 8 seconds.

Some flakes are caused by weird races in this code. Plus, if we
get things to write straight to files, we might see things in
there on post-mortem which happen after the python runner exits.
It's a bit less efficient, but much simpler. Let's see if it helps!
Some tests need a rework now, since we don't get a failure (except
eventual timeout), but they're simpler.

Over time, it has cost us more developer cycles than it has gained.
It has hidden intermittant bugs, and allowed cruft to accumulate:
when we eventually tried to figure out what was going wrong, the
actual change which caused it was now stale and forgotten.
This was a particular bane during the connectd rewrite, and I
worked through some issues which had occurred before, but were not
more likely.

Changelog-Deprecated: Plugins: `coin_movement` notification: `balance`, `credit`, `debit` and `fees` (use `balance_msat`, `credit_msat`, `debit_msat` and `fees_msat`)
We had json_add_amount_msat_only(), which was designed to be used to
print out msat fields, if we had sats.
However, we misused it, so split it into the three different cases:
1. json_add_amount_sat_msat: We are using it correctly, with a field called
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
interface, where "XXXsat".

Before this fix, there was the situation where a DEVELOPER=1 node would
announce non-public addresses on mainnet if detected. Since there
are some nodes on the internet that falsely report local addresses
we move this 'testing feature' to 'dev-allow-locahost' nodes.

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.

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..."
If we fund a channel between two nodes, then mine all the blocks to
announce it, any other nodes may see the announcement before the
blocks, causing CI to complain about "bad gossip":

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.
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 last line of the testcase was checking on the wrong node l3
instead of l1. l3 didn't had the plugins configured that would
produce the log entry we were looking for not to be present.
