dc18f3cd7b BOLTs: update which renames blinding terminology.
No code changes, just catching up with the BOLT changes which rework our
blinded path terminology (for the better!).

Another patch will sweep the rest of our internal names, this tries only to
make things compile and fix up the BOLT quotes.

1. Inside payload: current_blinding_point -> current_path_key
2. Inside update_add_htlc TLV: blinding_point -> blinded_path
3. Inside blinded_path: blinding -> first_path_key
4. Inside onion_message: blinding -> path_key.
5. Inside encrypted_data_tlv: next_blinding_override -> next_path_key_override

232fba878e wire: fix up messy patches (make extract-peer-csv)
They didn't actually apply properly!

I regenerated the dual-funding CSV from the latest commit
(091397fc0798c4b2bdb36dbaa9f5b4b1d4a463e1) and made it a single patch.

I tried doing the same for splicing, but the implementation has drifted
far from the spec, so I simply opted for a patch which didn't change anything.

You can see the resulting "wire/peer_wire.csv" is the same, except fields
are now in a less-random order!

4628e3ace8 channeld: Code to implement splicing
Update the lightningd <-> channeld interface with lots of new commands to needed to facilitate spicing.

Implement the channeld splicing protocol leveraging the interactivetx protocol.

Implement lightningd’s channel_control to support channeld in its splicing efforts.

Changelog-Added: Added the features to enable splicing & resizing of active channels.

Since this was merged, `make extract-peer-csv` was broken!

2. `blinding` -> `blinding_point`.

b3af5f5a2c spec: import latest onionmessage spec, based on routeblinding.
This is from 6e99c5feaf60cb797507d181fe583224309318e9

We renamed the enctlv field to encrypted_recipient_data in the spec, and the
new onion_message is message 513.  We don't handle it until the next patch.

Two renames:
1. blinding_seed -> blinding_point.
2. enctlv -> encrypted_recipient_data.

We don't do a compat cycle for our JSON APIs for these experimental
features only used by our own plugins, we just rename.

9224d9a500 gossipd: use modern 'sync_complete' field.
We assume if they set this to 0 (which nobody did previously), they're
using it as a modern flag and use it to indicate when they're
finished.  Otherwise, we count how many blocks they've sent and use
that to determine whether they've finished.
