When doing the updates on the plugin repo, I discovered that
this helper function got broken by the `listpeerchannels` upgrade.
Its rarely used in the main repo, just at the end of the pyln-testing
'pay' helper.
If unfixed, this bug may result in test flakes when using the `pay`
helper, because its not correctly waiting for all HTLCs to be resolved
before returning.
Changelog-None
It's a core concept in the spec which isn't directly exposed.

Changelog-EXPERIMENTAL: JSON-RPC: `listtransactions` `channel` and `type` field removed at top level.
We no longer use offers for "I want to send you money", but we'll use
invoice_requests directly. Create a new table for them, and
associated functions.
The "localofferid" for "pay" and "sendpay" is now "localinvreqid".
This is an experimental-only option, so document the change under
experimental only.

The goal here is to test the node validation, not whether we can
trigger the schema validation with bogus values. So we bypass the
verifying RPC wrapper.
We have to allow them (as otherwise `fees_collected_msat` in getinfo breaks),
but it means that actually, in_htlc_id might be missing in listforwards
(also, out_htlc_id might be missing, which we didn't catch before).

Fixes: #5628
This is just before the introduction of `get_json_id`, but has the
correct dependency constraints such that all packages can be updated
to >=v0.12 and we don't mix minor versions.
And document that we never know payment_hash.
Changelog-Added: JSON-RPC: `listforwards` now shows `in_htlc_id` and `out_htlc_id`
Changelog-Changed: JSON-RPC: `listforwards` now never shows `payment_hash`; use `listhtlcs`.
Normally, we'd use the delete_columns function to remove the old
`short_channel_id` string field, *but* we can't do that for sqlite, as
there are other tables with references to it. So add a FIXME to do
it once everyone has upgraded to an sqlite3 which has native support
for column deletion.

We didn't have optional Outpoints as arguments so far, so let's
backfill that.
Changelog-Changed: cln-rpc: The `wrong_funding` argument for `close` was changed from `bytes` to `outpoint`
Changelog-Added: JSON-RPC: `fundchannel`, `multifundchannel` and `fundchannel_start` now accept a `reserve` parameter to indicate the absolute reserve to impose on the peer.
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.
Some tests need to inspect it, but most don't, and I suspect I'm missing some
error messages due to this.

This allows us to re-use existing tests (assuming the call and fields
are covered by `cln-rpc` and `cln-grpc`) to test the full roundtrip
from test over the grpc interface to the json-rpc interface and back
again.
You can switch to the grpc interface by setting the `CLN_TEST_GRPC`
environment variable to 1, but for now only very few shims are
implemented (due to the non-generated nature of LightningRpc).
To test the grpc interface we'll want to emulate the JSON-RPC
interface as best we can, hence when talking to the grpc interface we
want to convert back into a parsed JSON format as LightningRpc would
have returned it. This is just the simplest way of closing the loop
here:
```
pyln-testing --grpc-> cln-grpc --grpc2json
^ |
| v
| JSON-RPC
| |
TEST v
^ CLN
| |
| v
pyln-testing <-grpc2py-- cln-grpc <- json2grpc
```
These may eventually end up in pyln-client, as they allow talking to
the GRPC interface exposed by cln-grpc, however for now they are used
for testing only. Once we have sufficient API and test coverage we can
move them and leave imports in their place.
Since we now log directly, we don't prepend the prefix ourselves, making it really
hard to tell *which* lightningd the log applies to!

Even though we generally wait until a node has seen the gossip,
that doesn't mean that connectd has processed it! This means when
we connect it may still send us "old" gossip.
So we set the OPT_GOSSIP_QUERIES bit, which means don't send until we
ask. But now it sends us WIRE_QUERY_CHANNEL_RANGE, so everyone needs
to filter that out.

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.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
So this was quite a journey:
- We want relative depdendencies (using the `path` argument) whenever
developing locally. Otherwise we would have to install each
dependency every time we change a single character, which
undoubtedly would cause us to waste time trying to debug an issue
just because we forgot to install.
- When publishing however we want to rely on the version number,
since the repo context gets lost upon publishing, and path
dependencies cause failures.
The solution then it seems is to use `dev-dependencies` (not that
surprising once you find it) with relative paths, so that `poetry
install` uses these over the normal dependencies (no idea how they
dedup them) and use `dependencies` when publishing. The paths are
still in there when publishing, but `pip install` ignores them.
I checked that `poetry install` from an unrelated project doesn't
accidentally use the path dependencies, even when adding them as
dev-dependencies. This should hopefully also allow installing them
as a repo link, though I can't test that right now.
We should be using amount_msat always. Many tests were not. Plus,
deprecating it simplifies the code.

msat on decode.

* datastore/deldatastore/listdatastore `key` can be singleton.
* delexpiredinvoice: `maxexpirytime` is not required, is a u64.
* invoice/delinvoice/listinvoice `label` can be an integer
* fundpsbt: many fields are u32 not number (JSON for int or float).
* invoice: `msatoshi` can be "any".
* invoice: `expiry` has a type (now must be numeric).
* invoice: `exposeprivatechannels` can be bool or array of scids.
* invoice: `deschashonly` added
* keysend: there's no "float" type, use "number" or "u32" etc.
* keysend: `routehints` is a valid arg, as is `extratlvs` (EXPERIMENTAL_FEATURES)
* listdatastore: `key` is not required.
* newaddr: `addresstype` can be "all"
* pay: `exemptfee` is "msat", new fields `locaofferid` and `exclude`
* sendonion: was mis-formatted, missed `localofferid` and `groupid` fields.
* sendpay: add `localofferid` and `groupid` params.
* signpsbt: add `signonly` param.

- Penalty txs were "3 CONSERVATIVE" now "12 ECONOMICAL".
- Normal txs were "4 ECONOMICAL" now "12 ECONOMICAL".
There can be no perfect levels, but we have had understandable
complaints recently about how high our default fee levels are.
Changelog-Changed: Protocol: channel feerates reduced to bitcoind's "6 block ECONOMICAL" rate.

You still shouldn't do this (you could get some transient failures),
but at least you have a decent chance if you reinstall over a running
daemon, instead of getting confusing internal errors if message
formats have changed.
Changelog-Added: lightningd: we now try to restart if subdaemons are upgraded underneath us.

Fixes: #4346
e.g. in test_closing_id we can get a spend from the first (closed) channel
in the same block as the open of the second. Half the time, we'll choose
the wrong one as scid.

Since we turned many errors into warnings, we want our tests to fail
when they happen unexpectedly. We make WARNING clear in the strings
we print, too, to help out.

This 'fixes' the `wait_for` helper by removing a pointless final
`time.sleep()`, thus potentially making the method return quicker.
The old code could have had three final states:
- success() := True
- Timeout and success() := True
- Timeout and success() := False
The new code has just two final state:
- success() := True
- Timeout and success() := False
It ensures the final `time.sleep()` is just the right amount before timeout.
And more importantly making it more readable :-)
Changelog-None
We are printing `repr(obj)` which is not pretty-printed, hard to read,
and can't even be copied and inspected to JSON tools. We now print the
JSONified and indented calls and responses for easier debugging based
on solely the logs (useful for CI!).
Changelog-Added: pyln-testing: The RPC client will now pretty-print requests and responses to facilitate log-based debugging.
We were getting a couple of starvations, so we need a fair filelock. I
also wasn't too happy with the lock as is, so I hand-coded it quickly.
Should be correct, but the overall timeout will tell us how well we
are doing on CI.
We were getting a number of incompatibility warning due to the
dependencies being expressed too rigidly. This losens the requirement
definitions to being compatible with a known good version, and while
we're at it we also bump all outdated requirements.
we got rid of push_msats for dual funded channels. this assumes that hte
peer will match an equal amount of sats as ours (the df_accepter.py
plugin will do this)

This was causing the following error
```
Exception in thread Thread-553:

Notice the second call to `.rstrip()` on the return value of `.append()`
Both my machine and apparently the CI tester machines regularly run
into issues with load on the system, causing timeouts (and
unresponsiveness). The throttler throttles the speed with which new
instances of c-lightning get started to avoid overloading. Since the
plugin used for parallelism when testing spawns multiple processes we
need to lock on the fs. Since we have that file open already, we'll
also write a couple of performance metics to it.
We sometimes have very specific sequences of tx broadcasts and blocks
being generated to confirm them. If the confirmation is missed the
test can completely get out of sync. Make debugging this easier by
logging what we confirmed.
Logs may contain non-ASCII and non-UTF8 symbols, which crashes the
tailer. It's better to replace them with a glyph representing
undecodeable symbols instead, and handle the issue further up the
call-chain.
We rely on it when logging, but didn't set it in the class, rather we
did in the sub-classes. This proved to be rather annoying to search
since it'd just fail silently and not log any output.
This will change the current hardwired PostgreSQL binary lookup mechanism to
utilizing the `pg_config --bindir` utility that should work better for most
distributions. The old method caused issues at least on Archlinux.
