GH was complaining about Node v12 being used in v2.2.4. We used to
hold back from this upgrade because v3 was breaking quotas, but we
should try again.
The channel selection did not consider the amounts that we are trying
to transfer, which in a multiplexed channel world could end up always
selecting a channel that is too small for the payment. We also log
which channel was selected based on the selector that is passed in,
allowing us to better follow the decisions.
Changelog-Fixed: pay: `sendonion` and `sendpay` will now consider amounts involved when using picking one channel for a peer
Debugging a number of payments showed that we sometimes waste a number
of attempts routing through a channel via its alias, rather than its
scid. This is because while we annotate the scid when it has been set,
we do not do so for the alias. The alias then is picked for routing
despite not having enough capacity, failing the attempt locally.
It can also happen that we alternate between scid and alias, doubling
the number of failed attempts before we can make progress.
This patch sets the hint for the alias to a capacity of 0 and disables
it as if the peer were offline. This means when available we'll always
use the scid, which is also far easier to read in the logs.
Changelog-Fixed: pay: We now track spendable amounts when routing on both the local alias as well as the short channel ID
If you miss a wait event, you can catch up by doing listinvoices and
getting the max of these fields. It's also a good debugging clue.

Now we have defined ordering, we can add a start param.

Changelog-Added: JSON-RPC: `listinvoices` has `index` and `start` parameters for listing control.
This will initially be for listinvoices, but can be expanded to other
list commands.
It's documented, but it makes promises which currently don't exist:
* listinvoice does not support `index` or `start` yet.
* It doesn't actually fire when invoices change yet.

Changelog-Added: JSON-RPC: `wait`: new generic command to wait for events.

Changelog-Added: JSON-RPC: `setchannel` adds a new `ignorefeelimits` parameter to allow peer to set arbitrary commitment transaction fees on a per-channel basis.
Recent cppcheck doesn't like our code; until we fix that, make it easy
to run every other source check.

Changelog-Deprecated: JSON-RPC: `commando-rune`, `commando-listrunes` and `commando-blacklist`.

This extracts the core checking functionality for a rune, so they can

We also document how the grpc test mode works, and why it currently
lacks coverage.
Changelog-Changed: pyln-testing: The grpc dependencies are now optional.
The presplitter modifier would split a payment before trying the first
attempt based on some common sizes. Its goal was to have smaller parts
in flight over different paths, in order to make it more difficult for
a forwarding node to learn payment amount. However it was causing some
issues for direct payments, and estimates on spendable amounts which
considers only the first HTLC being added, but presplitter would
always cause multiple HTLCs to be kicked off, causing the estimate to
be off.
Removing the presplitter fixes this, making draining channels easier,
and worse success rates, due to more HTLCs in flight directly
impacting the changes of getting stuck.
Changelog-Removed: pay: `pay` no longer splits based on common size, as it was causing issues in various scenarios.
These tests make assumptions about the presplitter behavior which
we'll remove in the next commit. We remove them here so we don't cause
temporary breaks in the git history.
While one side was not produced by us, we have a vested interest in propagating it.
