43f5304539 plugins/offer: allow offer to create send_invoice, refund and single_use offers.
refund offers are implied send_invoice offers.  And send_invoice offers
are implied single-use offers, though it can also make sense to have
a non-send_invoice offer be single-use.

3b7d0e7a62 common/json: make json_scan return an error string.
This makes for more useful errors.  It prints where it was up to in
the guide, but doesn't print the entire JSON it's scanning.

0726d2912e df-mfc: remove guard-rails for failures
This will cause blow ups for v2 multifundchannel attempts with failures,
but allows us to return the expected errors for single-shot

b040a893ed mfc: avoid off-by-one rounding errors when finding change fee
Since we round down in `amount_tx_fee`, find the change fee as the
difference between what we've already paid and what the combined/total

6e3c517611 mfc-df: if there's an error with a openchannel_signed, fail
Ideally we'd 'cure' the error and re-attempt, except that if this was a
bitcoin-backend 'failure to broadcast' then it really needs user
intervention to figure out what's wrong -- it's possible that the
peer successfully broadcast the transaction

723c16072a cleanups: feedback from Christian Decker review.
1. Hoist 7200 constant into the bolt12 heade2.
2. Make preimage the last createinvoice arg, so we could make it optional.
3. Check the validity of the preimage in createinvoice.
4. Always output used flag in listoffers.
5. Rename wallet offer iterators to offer_id iterators.
6. Fix paramter typos.
7. Rename `local_offer_id` parameter to `localofferid`.
8. Add reference constraints on local_offer_id db fields.
9. Remove cut/paste comment.
10. Clarify source of fatal() messages in wallet.

3b599b846e keysend: Check that the destination supports keysend upon init
We were blindly initiating the keysend payment, which could lead to
confusing outcomes. This adds a very specific error message to the
error returned.

Changelog-Fixed: keysend: Keysend now checks whether the destination supports keysend before attempting a payment. If not a more informative error is returned.

e186b2620a txprepare: Verify that outputs arg is an array
We were not checking that outputs is indeed an array, and just going
ahead creating the array of outputs. Since `tok->size` for a string is
0 we ended up ignoring the argument altogether and thus the created
transaction would end up only with a single change output.

54c57e7495 libplugin-pay: don't expose bolt11 details.
When we support bolt12, this won't exist.  We only need min_final_cltv_expiry,
routes and features, so put them into struct payment explicitly.

We move the default final ctlv out to the caller, too, which is clearer.
e.g. keysend was using this value, but it was hard to tell.
