This is consistent with our output changes, and increases consistency.
It also keeps future sanity checks happy, that we only use JSON msat
helpers with '_msat' fields.

Changelog-Changed: JSON-RPC: `invoice`, `sendonion`, `sendpay`, `pay`, `keysend`, `fetchinvoice`, `sendinvoice`: `msatoshi` argument is now called `amount_msat` to match other fields.
Changelog-Deprecated: JSON-RPC: `invoice`, `sendonion`, `sendpay`, `pay`, `keysend`, `fetchinvoice`, `sendinvoice` `msatoshi` (use `amount_msat`)
We were setting it on the root, but that doesn't get handed to
sendpay. Our schema doesn't *require* bolt11, either, so this was
missed (there could be a *bolt12* instead).

Changelog-Fixed: JSON-RPC: `listpays` always includes `bolt11` or `bolt12` field.

Changelog-Removed: protocol: support for legacy onion format removed, since everyone supports the new one.
1. The dijkstra can be temporary, doesn't need to last as long as pay cmd.
2. We fail multiple times in several places, so don't leak old failreason.
3. Make payments findable by our memleak detector.

Since we have the exact state of the channels from the `listpeers`
response we can filter out the ones that are not yet normal or not
anymore. This is more of a safety net, given that the `gossip_store`
should contain local disables, but better not be racy :-)
Changelog-None
And turn "" includes into full-path (which makes it easier to put
config.h first, and finds some cases check-includes.sh missed
previously).
config.h sets _GNU_SOURCE which really needs to be done before any
'#includes': we mainly got away with it with glibc, but other platforms
like Alpine may have stricter requirements.

Changelog-Changed: pay: The route selection will now use the log-propability-based channel selection to increase success rate and reduce time to completion
We bias by channel linearly by capacity, scaled by median fee.
This means that we effectively double the fee if we would use the
entire capacity, and only increase it by 50% if we would only use
1/2 the capacity.
This should drive us towards larger channels.

Changelog-Changed: Plugins: `pay` now biases towards larger channels, improving success probability.
We were checking against the wrong enum value, resulting in an
erroneous `pending` state as a final result.
Changelog-Fixed: pay: `pay` would sometimes misreport a final state of `pending` instead of `failed`
After recent header files clean-up it was not possible to
build c-lightning 7401b2682. This patch fixes it both for
Alpine Linux and OpenBSD.

There are a couple of ways this can happen, but we shouldn't crash.
Fixed#4488Fixes#4533
Changelog-Fixed: pay: Fixed an issue when filtering routehints when we can't find ourselves in the local network view.
We were counting the attempts including the root payment, which
resulted in an off-by-one error with the `test_pay_low_max_htlcs`
test. Counting the children of the root payment after the presplitter
had a go is the correct way to do it, since at that time we only have
one level in the tree, no need to recurse and potentially count
ourselves.
I don't know why it thinks that blockheight is INT_MAX, but
we shouldn't wait forever anyway.

1. We don't need to check for NULL before tal_count(NULL).
2. Use of json_for_each_arr iterator is probably better.
3. Weird indent fixed.

We were not aborting if we had routehints, even though all routehints
may have been filtered out.
Changelog-Fixed: pay: `pay` will now abort early if the destination is not reachable directly nor via routehints.
We would happily spin on attempts that are doomed to fail because we
don't know the entrypoint. Next up: remove routehints whose
entrypoints are known but unreachable.
The main responsibility of this new function is to mark a payment
process as terminated and set a reasonable error message, that will be
displayed to the caller. We also skip the remaining modifiers since
they might end up clobbering the message.
We fix up the test by using pay, instead of sendpay (and making pay log
the expected message).

Changelog-Changed: sendpay no longer extracts updates from errors, the caller should do it from the `raw_message`.
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.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
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.

I previously mistyped the rather lengthy conditions for failures, so
let's dissect it into its smaller components and add rationale behind
the individual parts of the decision.
