ee47b9370f common/bolt12_id: new common routine for creating path secrets.
invoice_path_id is actually a generic path_id thing, so rename it.

We're going to use the same scheme for path secrets and the tweak to
node_id when we create a fake pubkey for invoice_requests, so a new
header is appropriate.

f33c5188ef common: don't mention the contents of invalid parameters when in non-dev mode.
Shahana decided this was the optimal UX path, though I insisted that we still
report the actual problem directly when in dev mode, as a compromise.

3531414d18 lightningd: rename command_log() to command_logger()

7f2aedc76f common: BOLT update: option_anchors_zero_fee_htlc_tx is now simply "option_anchors".
This is a difficult transition for us: this string appears in channel

Changelog-Deprecated: JSON-RPC: `listpeers` `features` array string "option_anchors_zero_fee_htlc_tx": use "option_anchors" (spec renamed it).
Changelog-Added: JSON-RPC: `listpeers` `features` array string uses "option_anchors" for feature 22/23, following renaming in BOLT 9.
Changelog-Changed: JSON-RPC: `listclosedchannels`, `listpeerchannels`, `openchannel_update`, `openchannel_init`, `fundchannel`, `fundchannel_start` and `multifundchannel`: `channel_type` array `names` now contains "anchors" instead of "anchors_zero_fee_htlc_tx".

1d4783a756 lightningd: send CHANNEL_REESTABLISH ourselves on closed channels.
We used to fire up channeld to send this, but:
1. That's silly, we have all the information to make it ourselves.
2. We didn't do it if there was an error on the channel, which as of 24.02
   there always is!
3. When it did work, running channeld *stops* onchaind, indefinitely slowing recovery.

24ec17126c channeld: Adjust the feerate security margin profile
The feerate security margin is a multiplicative factor applied to the
feerate of some transactions in order to guarantee that the
transaction remains publishable and has a sufficient chance of being
confirmed, that we can base some of our decisions on that.

The multiplicative factor is >=1 and was so far a constant 2. This
might have been sensible in the low-fee environment, where the fees
are expected to oscillate, and almost guaranteeing that we will
eventually have rising feerates but in high-fee environments that is
no longer the case, and the 100% margin that the multiplicator 2
brings is excessive. We therefore opt to start out with 100%, then
linearly interpolate up to a given maxfeerate (which does not have to
be a real feerate ever reached, it just indicates the feerate after
which we apply the constant 10% margin.

Fixes #6974
Closes #6976
[Fixed up all the other changes required, including spendable calcualtion
 comments and unit test and pytest tests --RR]

The `struct notification` lost type-safety, but avoided a redundant
string.  The string is better, I think.

Since all notifications now contain an object of same name (some have
deprecated fields outside that), we can add helpers to do that, too.

Also, add some const (easy to do now we're typesafe!)

52b1ba2992 wallet: remove premature optimization when making payment.
We didn't write to db immediately, but waited until it the actual HTLC got
added (or failed).  That way we didn't have a separate transaction to
write the payment into the db, but the complexity is not worth it: it
makes the next refactors harder, since we can't use the normal
iterator patterns like we do with the rest of the db (as we have to add
the unstored ones).

We might as well also make sendpay return immediately: we used to return
once the HTLC had been confirmed sent, since we entered it in the db
at that point, but we can keep it simple now.

2de7171286 lightningd: fold funding tx depth into a single function.
Currently it's half done in funding_depth_cb, and half in
channeld_tell_depth.  It's very confusing as a result,
with splicing, dual-funding and zeroconf.

This does introduce a behaviour change: if a channel is NORMAL and
it gets reorganized, we force close (unless we were the one who funded
it, or it's zeroconf anyway).  This is safer than continuing to use
the channel in this case!

Some tests are changed to zeroconf to make them work, but v2 doesn't
support zeroconf, so that's removed.
