Let's tell the caller what channel_type they got!

Changelog-Added: JSON-RPC: `fundchannel`, `multifundchannel`, `fundchannel_start` and `openchannel_init`: new field `channel_type`.
And add a request schema for multifundchannel.
Changelog-Added: JSON-RPC: `fundchannel` and `multifundchannel` now take an optional `channel_type` parameter.

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
Changelog-None
We were putting out a lot of empty journal entries. Let's
stop doing that.
Now the wallet balance stays uninitialized until/unless you have
funds in it.
Fixes#5672
And we don't need to handle 0.9 lightningd which didn't include
allow-deprecated-apis in getmanifest call.

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.

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.

`struct column` has a dynamically allocated member, which is neater if
it is a tal object itself (we allocated the member off the array, instead).
We're about to add two new members, so clean this up first.

Changelog-Experimental: Plugins: `funder` option "lease-fee-base-msat" removed (deprecated in v0.11, use "lease-fee-base-sat")
Adds a "canonical" error handling in the module mcf.c,
adhering to the same convention we have adopted in flow.c.
So that when a function fails it signals the caller with an invalid
return value, or bool false, and it communicates an error message.
This switches the logging implementation from using the `log`-facade
to using the `tracing-subscriber` instead. This allows us to also tap
into the tracing instrumentation if desired, which was not possible
with `log`.
Changelog-Changed cln-plugin: The logging adapter now uses tracing-subscriber allowing the `tracing` ecosystem to be used. No format changes.
The `cln-plugin` can be used to create a plugin that registers
additional rpc-methods. However, it doesn't allow to specify the `usage`
of the command.
This change makes it possible to specify the `usage`. It should not
contain any breaking changes.
I've opted to add a new method called `rpcmethod_from_builder` to the
`Builder` struct. This approach allows us to add new parameters in the
future.

Changelog-Deprecated: `listchannels` no longer uses local knowledge to set `active` to false if disconnected.
This alters a few remaining tests, as well.

Changelog-Deprecated: JSON-RPC: `listchannels` listing private channels: use listpeerchannels
This breaks our tests a bit, which assumed we can always see ourselves
even if we don't have a proper channel.
Usually we would deprecate this first, but it's unlikely to break
anyone since it's a bit obscure that this worked at all.

Changelog-Changed: JSON-RPC: `listnodes` no longer shows private (peer) nodes: use listpeers
We temporarily use a second gossmap so we can just switch private info off
for listincoming and not listchannels.
Note that listchannels now uses the local alias (if no scid), so we have
to change that in the routehint caller.
Since we now *always* use a channel alias in hints if one exists, a
test broke, so fix that.
