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.

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.

Changelog-Deprecated: JSONRPC: `sendpay` `route` elements `msatoshi` (use `amount_msat`)
This prepares for when they start being u64, not strings with msat appended.
This has a strange side effect on our schema: despite the name,
decodepay's `fee_base_msat` is actually a u64, which we now convert to
msat on decode.

This is consistent with our output changes, and increases consistency.
It also keeps future sanity checks happy, that we only use JSON msat
helpers with '_msat' fields.

Types are fixed, in particular:
* rename "OutputDesc" to more consistent "outputdesc".
* rename "utxo" to more consistent "outpoint".
* it's "boolean" not "bool".
* "number" means int or float, usually it should be u32.
Specific commands:
* close `id` can be by channel id, scid.
* close `feerange` is a feerate type.
* 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.
* txprepare "outptus" typo.
* waitsendpay: add `groupid` and fix `partid` type.
* withdraw: `destination` is a bitcoin address, not a pubkey.

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

But this requires a watch-only wallet, and python-bitcoinlib doesn't support
multiple wallets, so we need to unload the original one, but then we need
to generate a block, so that can't generate a new address, so we need

This seems to trigger now, especially on PostgresQL (maybe it's faster

On my machine it should have produced:

but instead it produced:
/private/tmp/ltests-1p0v5z1j/.locks/lock-1631090663.105848
The mismatch resulted in a hang inside flock.
Path .resolve() seems to be causing problems for others as well. It appears the library was not meant to handle complex path situations and isn't maintained as such (see link reference).
Since we have already built a full path here anyway, the call to .resolve() appears redundant.

Users are more upset recently with the cost of unilateral closes
than they are the risk of being cheated. While we complete our
anchor implementation so we can use low fees there, let's
get less aggressive (we already have 34 or 18 blocks to close
in the worst case).
The changes are:
- Commit transactions were "2 CONSERVATIVE" now "6 ECONOMICAL".
- HTLC resolution txs were "3 CONSERVATIVE" now "6 ECONOMICAL".
- 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.

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 :-)
