Useful for regtest and testnet. Sure, you shouldn't use this on mainnet,
but I haven't restricted it because our users are usually pretty clever.

Changelog-Added: config: `force_feerates` option to allow overriding feerate estimates (mainly for regtest).
This has been reported several times on regtest, most recently by Gijs
van Dam. It turns out approx_max_feerate() was returning 0 in some
corner cases: we should *not* be using that value (as shown, it's
overly conservative) except as a ceiling on fee *increases*.

Changelog-Fixed: Protocol: don't ever send 0 fee_updates (regtest bug).
We don't do it for sendinvoice (yet?).

Changelog-EXPERIMENTAL: `fetchinvoice` can take a payer note, and `listinvoice` will show the payer_notes received.
We don't support it (yet), but update the spec to include it.
We include the previous field (recurrence_signature) as a shim for the
moment, for compat with existing nodes. It's ugly, but next release
we'll stop *sending* it, then finally we'll stop accepting it!

Changelog-EXPERIMENTAL: BOLT12 offers can now be unsigned, for really short QR codes.
100+ is for experimentation, modern spec practice is to assign feature bits
sequentially as PRs get added, to avoid later renumbering.
Still respect the old bit for now.

And even if we can't find *ourselves* because we have no channels
(we won't be able to pay, sure, but we can request an invoice!).

This also adds a `fetchinvoice-noconnect` option to suppress it too.

Changelog-EXPERIMENTAL: `fetchinvoice` and `sendinvoice` will connect directly if they can't find an onionmessage route.

And add the local_offer_id to the schemas too.

Changelog-EXPERIMENTAL: JSONRPC: `listoffers` now shows `local_offer_id` when listing all offers.
Discovered by the next test, oops.

Changelog-Fixed: JSONRPC: `listinvoice` no longer crashes if given an invalid (or bolt12) `invstring` argument.
We were actually using the last commit tx's size, since we were
setting it in lightningd. Instead, hand the min and desired feerates
to closingd, and (as it knows the weight of the closing tx), and have
it start negotiation from there.
This can be significantly less when anchor outputs are enabled: for
example in test_closing.py, the commit tx weight is 1124 Sipa, the
close is 672 Sipa!

Changelog-Changed: Protocol: Use a more accurate fee for mutual close negotiation.
Show amount they were trying to pay with, not invoice amount.
Also, show min fee in closing, not fee they offered.

We set amounts to a list, but then don't use the values except
as a boolean.
Make it a boolean, which should also speed the test up!

Incoming HTLCs are rejected by the HTLC logic if the payload contains
an even type that `lightningd` doesn't recognize. This is to prevent
us from accidentally accepting a payment that has extra semantics
attached (for example if we get a keysend payment and don't know what
to do with the TLV field containing the message we should reject it,
otherwise the overall semantics of the message delivery fail).
This lets us transition (with a few supporting changes) to closingd,
which will happily let them mutual close with us.
We already handle the case where this mutual close is redundant (for
packet loss), so this is easy.

Changelog-Added: Protocol: We will now reestablish and negotiate mutual close on channels we've already closed (great if peer has lost their database).
This supports reestablish on a closed channel: we tell channeld to
respond to the reestablish message appropriately, then close the
channel.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Let the callers do that (only channeld needs to do this).
We temporarily send an error on unknown reestablish in openingd, as
this mimic previous behavior and avoids breaking tests (it does leave
a BROKEN message in the logs though, so
test_funding_external_wallet_corners needs to ignore that for now.

In particular, if one side sees the final CLOSING_SIGNED and the other
doesn't, we won't talk when it reconnects.

It handles all the cases of retransmission, and in the normal case
retransmits shutdown and immediately returns for us to run closingd.
This is actually far simpler and reduces code duplication.

Changelog-Fixed: Protocol: We could get stuck on signature exchange if we needed to retransmit the final revoke_and_ack.
This was turned by at random by CI:
1. Alice has sent shutdown, but it still waiting for revoke_and_ack.
2. Bob has sent and received shutdown, and sent revoke_and_ack,
so it considers it time for signature exchange.
3. Disconnect before Alice received revoke_and_ack.
4. Reconnect, Bob is in closingd, which doesn't rexmit revoke_and_ack.
5. Timeout.

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).
