And initialize max to current height max when htlcs are already dead.
Turns out (thanks CI!) that MAX() of multiple columns is GREATEST() in
Postgres. That's clearer (MAX is used elsewhere for single columns),
so translate on the sqlite3 side.

We keep the now-removed chains field, and in deprecated mode, we set it.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-EXPERIMENTAL: bolt12: `chains` in invoice_request and invoice is deprecated, `chain` is used instead.
Main changes are:
1. Uses point32 instead of pubkey32.
2. Uses issuer instead of vendor.
3. Uses byte instead of u8.
4. blinded_path num_hops is now a byte, not u16 (we don't use that yet!).

We make it a first-class citizen internally, even though we won't use
it over the wire (at least, non-experimental builds). This scheme
follows the latest draft, in which features are flagged compulsory.
We also add several helper functions.
Since uses the *even* bits (as per latest spec), not the *odd* bits,

Changelog-EXPERIMENTAL: BOLT12 offers can now be unsigned, for really short QR codes.
This allows us to ensure a packet is read by the other end, but we
don't read anything else from them or write anything to them.
Using '+' is similar, but because it closes the connection, the peer
might notice before receiving the packet (such as if it does a write).

We should actually be including this (as it may define _GNU_SOURCE

often didn't, because check-includes would complain that the headers
included it too.

Instead of a boutique message, use a "real" channel_announcement for
private channels (with fake sigs and pubkeys). This makes it far
easier for gossmap to handle local channels.
Backwards compatible update, since we update old stores.
We also fix devtools/dump-gossipstore to know about the tombstone markers.
Since we increment our channel_announce count for local channels now,
the stats in the tests changed too.

There's a few structs/wire calls that only exist under experimental features.
These were in a common file that was shared/used a bunch of places but
this causes problems. Here we move one of the problematic methods back
into `openingd`, as it's only used locally and then isolate the
references to the `witness_stack` in a new `common/psbt_internal` file.
This lets us remove the iff EXP_FEATURES inclusion switches in most of
the Makefiles.
dual funding needs the max-witness-len and utxo fields set for every
input. we should add them when we create a 'fundpsbt', so that every
psbt that c-lightning generates is dual-funding ready
v2 channel open uses a different method to derive the channel_id, so now
we save it to the database so that we dont have to remember how to
derive it for each.

It's now only needed by devtools/mkfunding, so include a reduced one
there, and this also means we remove tx_spending_utxos().

Update the `bitcoin_tx_add_input` interface to accept a witness script
and or scriptPubkey.
We save the amount + witness script + witness program (if known) to

now that witness script data is saved into the tx/psbt which is
serialized across the wire, there's no reason to use witscript to do
this. good bye witscript!
When we have only a single member in a TLV (e.g. an optional u64),
wrapping it in a struct is awkward. This changes it to directly
access those fields.
This is not only more elegant (60 fewer lines), it would also be
more cache friendly. That's right: cache hot singles!
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
common/onion is going to need to use this for the case where it finds a blinding
seed inside the TLV. But how it does ecdh is daemon-specific.
We already had this problem for devtools/gossipwith, which supplied a
special hsm_do_ecdh(). This just makes it more general.
So we create a generic ecdh() interface, with a specific implementation
which subdaemons and lightningd can use.

Header from folded patch 'fixup':
fixup! devtool/blindedpath: primitive tool to make blinded onions.
On decode, don't mess with op.ephemeralkey, since it will be used to derive
the next hop.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
For messages, we use the onion but payload lengths 0 and 1 aren't special.
Create a flag to disable that logic.

This is in preparation for messages, which want this as their assocdata.
Plus, it's a bit cleaner rather than creating a tmp tal array.
