This means we don't have to manually choose what to link against,
which is much of the complexity of our Makefiles: the compiler will
automatically use any object files it needs to link.
We already do this for ccan as libccan.a, now we have libcommon.a.
We don't link against it for *everything*, as some tests require their own
versions.
Notes:
1. I get rid of the weird plugins/test/Makefile2 (accidental commit?)
2. Many tests change due to update-mocks.
3. In some places I added the missing dependency on the Makefile itself, though most are in the next
patch.

Changes:
* Fields renumbered to their draft values + billion.
* offer_recurrence now comes in compulsory or optional (backwards compat) flavors.
* `proportional_amount` is now inside `offer_recurrence_base` not `offer_recurrence_paywindow`.
* New field `invreq_recurrence_cancel`.

Changelog-EXPERIMENTAL: Draft specification for recurring offers changed: old recurring offers will no longer work.
fetchinvoice is still good for detailed diagnostics and handling
recurring invoices and alternate currencies, but this covers the
"throw some sats" case well.
Changelog-Added: JSON-RPC: `xpay` can now pay a simple offer directly, rather than requiring fetchinvoice first.

Changelog-Added: Plugins: `xpay` now publishes `pay_part_start` and `pay_part_end` notifications on every payment send attempt.
Eduardo points out that payment_failed kind of over-promises: it may
actually not fail the payment now (with slow mode).
It's more an indiciation that we're not trying any more payment parts,
so rename it to payment_give_up.

We can create this scenario by having one path force close. We take
the opportunity to log this, even in non-slow-mode, since it's interesting
(not our bug, but someone just lost money!).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This was requested by Michael of Boltz; it's mainly useful if you plan to
try failed payments on a *different* node. In that case, there's a
theoretical possibility that slow parts of this payment could combine with
that from a different node and overpay.
We don't allow this from the same node, already.
Changelog-Added: xpay: `xpay-slow-mode` makes xpay wait for all parts of a payment to complete before returning success or failure.

1. Don't rely on the current attempt, make caller calculate total.
2. Save preimage inside attempt, for slow mode.
3. Hoist it higher in the file.

Don't print unnecessary log entries every time we receive an rpc_command
hook event. Only log when `pay` is called.

This is deeply annoying, and we may have to support this properly
(using a separate algorithm entirely) if other implementations don't
fix their crap.

Changelog-Fixed: Plugins: xpay: suppress multi-part payment if invoice doesn't allow it (please, fix your nodes!)
Default goes to stderr for LOG_UNUSUAL and higher.
We have to whitelist more cases in map_catchup so we don't spam the logs
with perfectly-expected (but ignored) messages though.

Note that the slight code reorder changes the JSON order, which is generally
undefined, but our doc checker is very strict!
Changelog-Changed: `xpay` now gives the same JSON success return as documented by `pay` when `xpay-handle-pay` is set.

maxfeepercent is use by Zeus, so let's make that work.
maxfee is more precise, so it's the only xpay option (maxfee was added
to pay later).
[ Fix to ppm logic by Lagrang3, thanks! --RR ]
Fixes: https://github.com/ElementsProject/lightning/issues/7926
Changelog-Changed: JSON-RPC: With `xpay-handle-pay` set, xpay will now be used even if `pay` uses maxfeeprecent or exemptfee parameters (e.g. Zeus)

This means that it gets shown in listsendpays: omitting this broke spark, apparently!
Changelog-Changed: `xpay` now populates more fields, so `listsendpays` and `listpays` show `destination` and `amount_msat` fields for xpay payments.

Changelog-None: xpay is new this release.
In fact, there are several places where we try to decode old invoices,
and they should all work. The only place we should enforce expiration is
when we're going to pay.
This also revealed that xpay wasn't checking bolt11 expiries!

Changelog-Fixed: JSON-RPC: `decode` refused to decode expired bolt12 invoices.
pay does this, xpay does not. Which means if a block comes in (or you're behind),
you get gratuitous failures:

Changelog-None: xpay is new this release.
This is required for VLS which wants to know (and potentially decline) invoices
we're trying to pay.
As a nice side effect, our "check" command for xpay now does much more thorough
checking of arguments.
