We still support channels opened without it, but you can no longer open new ones without it.

It fails because this is an array of enum values, which is a
combination we hadn't seen before. Replacing this with a manually
managed enum, since it is likely we'll want to reuse it in the future.
Min. Cost Flow does not take into account fees when computing a flow
with liquidity constraints.
This is a work-around solution that reduces the amount on every route to
respect the liquidity bound. The deficity in the delivered amount is
solved by running MCF once again.
Changes:
1. the function `flow_complete` allocates amounts to send over the set of routes
computed by the MCF algorithm, but it does not allocate more than liquidity
bound of the route. For this reason `minflow` returns a set of routes that
satisfy the liquidity bounds but it is not guaranteed that the total payment
reaches the destination therefore there could a deficit in the delivery:
`deficit = amount_to_deliver - delivering`.
2. in the function `add_payflows` after `minflow` returns a set of routes we
call `flows_fit_amount` that tries to a allocate the `deficit` in the routes
that the MCF have computed.
3. if the resulting flows pass all payment constraints then we update
`amount_to_deliver = amount_to_deliver - delivering`, and the loop
repeats as long as `amount_to_deliver` is not zero.
In other words, the excess amount, beyond the liquidity bound,
in the routes is removed and then we try to allocate it
into known routes, otherwise we do a whole MCF again just for the
remaining amount.

We stopped doing empty journal logs, so we no longer need to switch
our log severity based on whether or not an account exists.
Should make bookkeeper less chatty and remove noisy logs

We were putting out a lot of empty journal entries. Let's

Unfortunately, this is awkward: we just copy through most requests,
so we can't easily add a "deprecation" field to each one. So we do
a notification if the next command has a different deprecation status
than the global one, but that requires opt-in from the plugin.
We didn't previously document the subscriptions array, so do that now.

Changelog-Added: Plugins: `deprecated_oneshot` notifiction subscription to change deprecated status for a single command.
I did some CHANGELOG and git digging to see when these were deprecated, and
some were very old (v0.8.2!). But since they didn't warn users loudly, I
chose to do so this release only.
I renamed ld's `deprecated_apis` to `deprecated_ok` to make sure I
caught them all.

Changelog-Added: JSON-RPC: `deprecations` to enable/disable deprecated APIs from this caller.
In this case the cmd is `sql` but the field we're talking about is from
a different command, so we need a new libplugin API.
Note: there are still no deprecations in any tables used by `sql`, so this
is a bit moot for now.

This allows the user to specify the feature *by name*, and hopefully
complain to the developer to fix their code, knowing it will be removed entirely
in the next release!

When we allow deprecation to be set per-connection, we need to
generalize this approach. Instead of filtering out deprecated
fields at schema loading, we need to load them, then refuse
to serve deprecated fields on a per-request basis.

Updating this every release was just busywork, and it turns out we don't actually
care: if something is marked deprecated we want to make it optional, whenever
it is for, and the only real test is if it was added before our lowest-supported
version we can consider it non-optional.

Each feature has a name, and says when deprecation begins and ends.
There's an API coming to allow you to re-enable on a per-feature basis
even if it's ended (as long as it's not been removed from the code ofc!).
Default end is 6 months after deprecation, i.e. we complain about it
at that point, if we can detect its use.
e.g, a standard deprecation in v24.05:
v24.02: allowed
v24.02 with mods: allowed
master after v24.02: allowed unless deprecated APIs disabled.
v24.05: allowed unless deprecated APIs disabled.
v24.08: allowed unless deprecated APIs disabled.
v24.11: allowed unless deprecated APIs disabled, but logs at BROKEN level.
v25.02: allowed only if --i-promise-to-fix-broken-api-user=FEATURE.
v25.05: code is actually removed.
