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()

f2b033d7e1 lightningd: move all chainheight logic into setup_topology.
Handling half in main() and half here was a mess.  And the name
"max_blockheight" was poor: it was the max in the db, or UINT32_MAX,
but then we changed it depending on what height we wanted to start at.

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

be more difficult in future.

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".
Changelog-Changed: lightningd: `--list-features-only` now lists "option_anchors" instead of "option_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.

Fixes: https://github.com/Blockstream/greenlight/issues/433

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]

d8c06dccac global: expose all fmt_X functions for direct use, make uniform.
We have various functions to convert to a string, rename them all so we can
count on fmt_X being the formatter for struct X, and make them all return
`char *`.

Sometimes they existed but were private, sometimes they had a
different name.  Most take a pointer, but simple types pass by copy:
short_channel_id, amount_msat and amount_sat.

The following public functions changed:
1. psbt_to_b64 -> fmt_wally_psbt.
2. pubkey_to_hexstr -> fmt_pubkey.
3. short_channel_id_to_str -> fmt_short_channel_id (scid by copy now!)
4. fmt_signature -> fmt_secp256k1_ecdsa_signature
5. fmt_amount_sat/fmt_amount_msat pass copy not pointer, return non-const char *.
6. node_id_to_hexstr -> fmt_node_id

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.
