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

Now the wallet balance stays uninitialized until/unless you have

Now _msat fields are all integers (last conversion 23.08) we can simply
leave them alone, rather than trying to convert them.
And for turning Millisatoshi into JSON, we simply globally replace the
default encoding function to try ".to_json()" on items, which allows
anything to be marshalled.
The global replacement was interfering with other uses of JSON, such
as the clnrest plugin.

Changelog-Changed: pyln-client: no longer autoconverts _msat field to Millisatoshi class (leaves as ints).
Since the class interacts with int very well now, we don't have to
make explicit accesses, so it's easy to write code which works with
Millisatoshi or int.
Also, don't access rpc.decoder in one test, it's unnecessary.

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.

l2 gave us a routehint, but it should have seen l1 as a dead-end. It
didn't due to the presence of a channel alias, which was a bug. We're
about to fix this, which breaks the test.

This is redundant if it's a public channel, but vital if it's not. Publishing unconditionally makes
it easier for gossmap: we create a local modification all the time, even if redundant (and we can
have the actual capacity ceiling accurate in this case, since we know it for local channels).

Adds tests for when the connection fails during
1) splice tx_signature
2) splice commitment_signed
Fleshed out the reestablish flow for these two cases and implemented the fixes to make these reestablish flows work.
Part of this work required changing commit process for splices: Now we send a single commit_part for the splice where previously we sent all commits, and accordingly, we no longer revoke in response.
Changelog-Fixed: Implemented splicing restart logic for tx_signature and commitment_signed. Splice commitments are reworked in a manner incompatible with the last version.
Since these worked in v23.08, we can't just rename them. So if they are
used and unclaimed, we should rename them internally (if they're claimed,
it's probably clightning-rest, and we should *NOT* touch them!).

Changelog-Deprecated: Plugins: `clnrest` parameters `rest-port`, `rest-protocol`, `rest-host` and `rest-certs`: prefix `cln` to them
This will allow users to use clnrest with c-lightning-REST without conflicts.
It was required for applications to have enough time for migrating from c-lightning-REST to clnrest.
Changelog-Changed:
config option `rest-certs` changed to `clnrest-certs`
config option `rest-protocol` changed to `clnrest-protocol`
config option `rest-host` changed to `clnrest-host`
config option `rest-port` changed to `clnrest-port`
config option `rest-cors-origins` changed to `clnrest-cors-origins`
config option `rest-csp` changed to `clnrest-csp`
We have a global JSON encoder hack, which means that any field ending in msat gets special treatment (so we can safely talk to lightningd, even if a field expects satoshi amounts, we are explicit). However, requests uses the JSON parser and DOES NOT want this conversion when sending it out as an HTTP response!
The simplest local fix we could find was Shahana's suggestion to iterate and covert away from Millisatoshi(): the reverse of what our JSON encoder does.

Link to #6436.
Here, we split up what was "commit_received" into two phases:
- commit-ready, where we're about to send our commitment tx to
peer
- commit-received, when we've gotten the commitment tx from our
peer
This lets us do the right thing (as far as the spec is concerned) with
returning the correct 'next_funding_txid' on reconnect (later commits).
