Again, we should use the real channel_type, but we approximate.

Changelog-Added: Protocol: private channels will only route using short-channel-ids if channel opened with option_scid_alias-supporting peer.
We *should* remember the channel type, since this is only required
if they set the channel_type to include option_scid_alias.
However, since we support channel upgrade, channel_type really needs
a new table. I have a patch for that, from my abandoned original
"fastopen" branch for aliases, but it's too big a chance for rc2 IMHO.
Meanwhile, we allow exposeprivatechannels's scids to be either real or
the aliases.

Changelog-Added: Protocol: invoice routehints will use fake short-channel-ids for private channels if channel opened with option_scid_alias-supporting peer.
Track rebalances, and report income events for them.
Previously `listincome` would report:
- invoice event, debit, outgoing channel
- invoice_fee event, debit, outgoing channel
- invoice event, credit, inbound channel
Now reports:
- rebalance_fee, debit, outgoing channel
(same value as invoice_fee above)
Note: only applies on channel events; if a rebalance falls to chain
we'll use the older style of accounting.
Changelog-None
When traversing the list we call `command_finished` which modifies the
list we are traversing. This ensures we don't end up advancing in the
list iteration.
Reported-by: Rusty Russell <@rustyrussell>
Technically this is a use-after-free since `command_finished` frees
the `cmd` which is also the parent of `p`, so reset it early. All
paths lead to `command_finished` so setting it early is ok.

Suspended payments now have the same groupid as the actual attempt,
this allows us to identify pay calls that were suspended due to us and
terminate only those.
Changelog-Fixed pay: Fixed a crash when `pay` was called multiple times while an attempt was already in progress.
This should prevent us from accidentally completing a payment twice,
when replaying the result of an actual attempt against pay call that
was suspended due to it still being pending.
AFAICT we should have been doing this since we started sending and
receiving it, but didn't.

Changelog-Added: Protocol: we now advertize the `option_channel_type` feature (which we actually supported since v0.10.2)
We were seeing flakes due to channel closures on intermidiary nodes if
the blocks came too fast.
If we use a star topology it's actually what we want and it's much simpler to
figure out what's going on.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We don't actually care how it does it, just that it ends the HTLCs,
so simplify this logic which tries to match it exactly.
This also fixes the flake where we would sometimes close the upstream
channels, simply because we now wait at least one second per block.

Previously, "funding_locked" was always "true"!

1. Unbalanced backticks and missing space in bookkeeper line.
2. Rephrase emergency backup to not overpromise.
3. "logging" and "lightnignd" are not correct title, use "Config".
4. JSON-RPC not JSONRPC in one place.
5. Don't include empty EXPERIMENTAL section (I checked, it really was empty!)

First, how we record "our_funds" and then apply pushes vs lease_fees
(for liquidity ad buys/sales) was exactly opposite.
For pushes we were reporting the total funded into the channel, with the
push representing how much we'd later moved to the peer.
For lease_fees we were rerporting the total in the channel, with the
push representing how much was already moved to the peer.
We fix this (from a view perspective) by re-adding lease fees to what's
reported in the channel funding totals. Since this is now new behavior
(for leased channel values), we added new fields so we can take the old
field names thru a deprecation cycle.
We also make it possible to differentiate btw a push and a lease_fee
(before they were all the same), by adding to new fields to `listpeers`:
`fee_paid_msat` and `fee_rcvd_msat`.
This allows us to avoid math in the bookkeeper, instead we just pick
the numbers out directly and record them.
Fixes#5472
Changelog-Added: JSON-RPC: `listpeers` now has a few new fields for `funding` (`remote_funds_msat`, `local_funds_msat`, `fee_paid_msat`, `fee_rcvd_msat`).
Changelog-Deprecated: JSON-RPC: `listpeers`.`funded` fields `local_msat` and `remote_msat` are now deprecated.
9cad7d6a6a changed the behavior of `channel_active`, which slightly
broke how our balance snapshots work (we need info about channels that
aren't on-chain yet).
This patches adds AWAITING_UNILATERAL back in.
```
# 0x0100 = channel_announcement
# 0x0102 = channel_update
# (Node announcement may have any timestamp)
types = Counter([m[0:4] for m in msgs])
assert types['0100'] == 1
> assert types['0102'] == 2
E assert 1 == 2
tests/test_gossip.py:324: AssertionError
```
Examining the logs shows that we ask l4 for timestamps
"first_timestamp=1658892115 timestamp_range=13", and the timestamp on
the missing update is exactly `1658892128`.
So round the end time up by 1 for filtering.

We used to tell connectd to remember our connect delay, and hand it
back (increased if necessary).
Instead, simply record when we last tried to connect. If it was less
than 10 minutes ago, double delay (up to 5 minutes max), otherwise
reset delay to 1 second.
This covers all scenarios: whether we reconnect then immediately
disconnect, or never successfully connect, it doesn't matter.

Fixes: #5453
Keep the accounts as an 'append only' log, instead we move the marker
for the 'channel_open' forward when a 'channel_open' comes out.
We also neatly hide the 'channel_proposed' events in 'inspect' if
there's a 'channel_open' for that same event.
If you call inspect before the 'channel_open' is confirmed, you'll see
the tag as 'channel_proposed', afterwards it shows up as
'channel_open'. However the event log rolls forward -- listaccountevents
will show the correct history of the proposal then open confirming (plus
any routing that happened before the channel confirmed).
We need a record of the channel account before you start sending
payments through it. Normally we don't start allowing payments to be
sent until after the channel has locked in but zeroconf does away with
this assumption.
Instead we push out a "channel_proposed" event, which should only show
up for zeroconfs.
This was originally done as part of the bookkeeper introduction, but it deserves its
own patch (and that one didn't remove the bitcoin/chainparams.o from the individual
requirements lines).

`lightningd` has an option --wallet that lets you supply a database dsn
string to connect to a sqlite3/postgres database that's hosted/stored
elsewhere.
This adds the `--bookkeeper-db` option which does the same, except for
the bookkeeping data for a node!
Note that the default is to go in the `lightning-dir` in a database
called `accounts.sqlite3`
First off, when we pull data out of JSON, unescape it so we don't end up
with extraneous escapes in our bookkeeping data. I promise, it's worth
it.
Then, when we print descriptions out to the csvs, we gotta wrap
everything in quotes... but also we have to change all the double-quotes
to singles so that adding the quotes doesn't do anything untoward.
We also just pass it thru json_escape to get rid of linebreaks etc.
Note that in the tests we do a byte comparison instead of converting the
CSV dumps to strings because python will escape the strings on
conversion...
So we print out invoice fees on the same line for those CSVs! This means
we have to do a little bit of gymnastics (but not too bad):
- we save the fee amount onto the income event now so we can use
it later
- we ignore every "invoice_fee" event for the koinly/cointracker
Note that since we're not skipping income events in the loops we also
move the newline character to the start of every `_entry` function so
skipped records dont incur empth lines.
Changelog-Added: bkpr: print out invoice fees on the same line for `koinly` and `cointracker` csv types
