Christian Decker 05a3be15a3 pay: Fix use-after-free issue with routehints in shortlived payments
This was triggered by having some part being started after the overall
command already gave up, cleaning up the `cmd` context from which the
routehints were allocated. The early exit of the command, as a result
from a terminal state does not guarantee that no later attempt will
try to find a route, especially if the attempt was started before we
knew that it is doomed.

Christian Decker 40e9d60ce0 pay: Do not clobber error messages if we fail decoding a bolt11
We were automatically falling back to bolt12 decoding, clobbering the
fail message. Ultimately resulting in confusing error
messages (expected prefix lni but got lnbtrc). Now we first determine
which decoding we're trying to do, and then only decode accordingly.

Changelog-Fixed: pay: Report the correct decoding error if bolt11 parsing fails.

Christian Decker e677486fcc pay: Check for self-payments before attempting to pay
This duplicates the check in libplugin-pay.c, with a more concise

Rusty Russell 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.

Rusty Russell 9fe612db20 plugins/pay: allow bolt12 invoices (EXPERIMENTAL_FEATURES).

Rusty Russell 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.

Rusty Russell 191355e0e7 pay: fix handling of legacy vs tlv encoding.
As revealed by the failure of tests in #3936, where we ended up trying
to send a partial payment using legacy style, we are not handling
style properly.

1. BOLT9 has features, so we can *know* that the destination supports
   MPP.  We may not have seen a node_announcement.
2. We can't assume that nodes inside routehints support TLV.
3. We can't assume direct peers support TLV.

The keysend code tried to fix this up, so I'm not sure that this caused
the issue in #3968, though.

Christian Decker 5776a33116 paymod: Activate paymod and move legacy pay to `legacypay` command
As suggested during the paymod-03 review it is better to activate the new code
right away, and give users an escape hatch to use the legacy code instead. The
way I implemented it allows using either `legacypay` or `pay` and then set
`legacy` to switch to the other implementation.

Changelog-Added: JSON-RPC: The `pay` command now uses the new payment flow, the new `legacypay` command can be used to issue payment with the legacy code if required.
