Alpine no longer has a `python` (2) package, which is fine because it doesn't seem to be needed. Also, the listed commands didn't result in all needed dependencies being installed for runtime, so I've added that in an additional step.

Changelog-Fixed: Plugins: `keysend` now removes unknown even (technically illegal!) fields, to try to accept more payments.
Mac is updating to using zsh in general.
The “for i in” reads strings with spaces as a single entry instead of multiple entries as sh did.
Using “while read” … “<<< $var” makes it treat each space as a new entry.
Changelog-None
We don't actually process onion messages here any more (they moved to
connectd), but the flag and object files were still linked.

It's been obsoleted and needs replacing; less confusing if we remove
it first.
Also, these fields are now present even without an expermintal build
(we'll control at runtime).

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.
If a channel goes offline while the count of outstanding outgoing HTLCs
exceeds the limit that we enforce against the peer, then the channel
could never be brought online again because `add_htlc` called by
`channel_force_htlcs` in `channeld/full_channel.c` would return
`CHANNEL_ERR_TOO_MANY_HTLCS`. The protocol specification actually does
allow us to exceed the limits that we are enforcing against the peer;
we are only prohibited from exceeding the limits that the peer is
enforcing against us. `add_htlc` takes an `enforce_aggregate_limits`
parameter that appears to have been intended for `channel_force_htlcs`
to exempt the local node from obeying the limits that it is enforcing
against the peer, but this parameter was only being respected for the
total HTLC value-in-flight check but not for the HTLC count check. This
commit respects the parameter for the HTLC count check as well and
resolves the problem of "Could not restore HTLCs".
Fixes: #5636
Changelog-Fixed: channeld: Channel reinitialization no longer fails when the number of outstanding outgoing HTLCs exceeds `max_accepted_htlcs`.
"sphinx_add_hop" takes a literal hop to include,
"sphinx_add_modern_hop" prepends the length. Now we always prepend a
length, make it clear that the literal version is a shortcut:
* sphinx_add_hop -> sphinx_add_hop_has_length
* sphinx_add_modern_hop -> sphinx_add_hop
In addition, we check that length is actually correct! This means
`createonion` can no longer create legacy or otherwise-invalid onions:
fix tests and update man page to remove legacy usage.

Changelog-Changed: JSON-RPC: `createonion` no longer allows non-TLV-style payloads.
We still have an "enum forward_style" for the database, where old-style
forwards can still exist.

Changelog-Removed: Protocol: we no longer forward HTLCs with legacy onions.
We used to ensure the l3<->l4 channel was private by
simply not mining enough blocks to announce. Then
we started mining 13 blocks to close the channel, and
it will get announced, causing a failure:
```
assert non_public(l2) == []
> wait_for(lambda: non_public(l3) == [scid34, scid34])
...
> raise ValueError("Timeout while waiting for {}", success)

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).

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.
Otherwise what the hook sees is actually a lie, and if it sets it
we might override it.
The side effect is that we add an explicit "forward_to" field, and
allow hooks to override it. This lets a *hook* control channel
choice explicitly.
Changelod-Added: Plugins: `htlc_accepted_hook` return can specify what channel to forward htlc to.

This is the minimal change to meet the desired outcome of https://github.com/lightning/bolts/issues/934
which wants to give obsolete-db nodes a chance to fix things up, before we
close the channel.
We need to dance around a bit here, since we *will* close the channel if
we receive an ERROR, so we suppress that.

We needed to clone a lot since we were using a non-mutable borrow of
the cln-rpc version to then create the cln-grpc version. This alone
reduces the number of allocations of the `listpeers` test from 52
allocations to 38.
We filter based on the environment variable `CLN_PLUGIN_LOG`,
defaulting to `info` as that is not as noisy as `debug` or `trace`, at
least libraries will not spam us too heavily.
Changelog-Added cln-plugin: The logs level from cln-plugins can be configured by the `CLN_PLUGIN_LOG` environment variable.
We had a bit of a chicken-and-egg problem, where we instantiated the
`state` to be managed by the `Plugin` during the very first step when
creating the `Builder`, but then the state might depend on the
configuration we only get later. This would force developers to add
placeholders in the form of `Option` into the state, when really
they'd never be none after configuring.
This defers the binding until after we get the configuration and
cleans up the semantics:
- `Builder`: declare options, hooks, etc
- `ConfiguredPlugin`: we have exchanged the handshake with
`lightningd`, now we can construct the `state` accordingly
- `Plugin`: Running instance of the plugin
Changelog-Changed: cln-plugin: Moved the state binding to the plugin until after the configuration step
