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.

Note that we remove the redundant "is this the correct chain?"
check, since bolt11_decode and bolt12_decode do that internally
anyway (this was changed in 924cc04bd2).

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.

Fixes: #3926
(probably)
Changelog-Fixed: pay: Also limit the number of splits if the payee seems to have a low number of channels that can enter it, given the max-concurrent-htlcs limit.
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.

Changelog-Fixed: `pay` will now make reliable multi-part payments to nodes it doesn't have a node_announcement for.
We have sanity checks in there that it's a valid point. Simply store
the JSON token like we do with others.

listpays: make doc-all missed
Changelog-Added: JSON-RPC: `listpays` can be used to query payments using the `payment_hash`
Changelog-Added: JSON-RPC: `listpays` now includes the `payment_hash`
Changelog-Fixed: pay: Fixed a bug where routehints would be ignored if the payment exceeded 10,000 satoshi. This is particularly bad if the payee is only reachable via routehints in an invoice.
We sum up the amounts just like we do with `amount_sent`, however we may have
parts that don't have that annotation, so make it optional.
Suggested-by: Rusty Russell <@rustyrussell>
Changelog-Fixed: plugin: `bcli` no longer logs a harmless warning about being unable to connect to the JSON-RPC interface.
Changelog-Added: plugin: Plugins can opt out of having an RPC connection automatically initialized on startup.
Changelog-Added: The MPP presplit modifier splits large payments into 10k satoshi parts to maximize chances of performing the payment and to obfuscate the overall amount being sent.
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.

This commit collects the changes required to the tests caused by the changes
to the `pay` and `paystatus` commands. They are also rather good hints as to
what these changes entail.
These are primarily the fee and cltv constraints that we need to keep up to
date in order to give modifiers a correct view of what is and what isn't
allowed.
We can have quite detailed information about our local channels, so call
`listpeers` before the `getroute` call on the root payment, to seed that
information in the channel_hints.
Since we end up consolidating some of the return values for `pay` and
`paystatus` and change the public interface we need to add the compatibility
flag and guard the switchover behind it.
We need to keep them around so we can inspect them later. We'll also need a
background cleanup every once in a while to free some memory. More on that in
a future commit.
This is likely a bit of overkill for this type of functionality, but it is a
nice first use-case of how functionality can be compartmentalized into
modifiers. If makes swapping retry mechanisms in and out really simple.
