This involves removing some fields from the now-misnamed routing.h
datastructures, and various internal messages.
One non-obvious change is to our "keepalive" logic which refreshes
channels every 13 days: instead of using the 'enabled' flag on the
last channel broadcast to decide whether to refresh it, we use the
local connected status directly.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
An "active" channel may still be CHANNELD_AWAITING_LOCKIN, so have ->scid NULL.
You can only trigger this by trying to sendpay to the node using a
manual route, since routing would never use such a channel.

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`.
The fetchinvoice and offers plugins disable themselves if the option
isn't enabled (it's enabled by default on EXPERIMENTAL_FEATURES).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: `experimental-offers` enables fetch, payment and creation of (early draft) offers.
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.

This is for offers which have `send_invoice`: we need to associate the
payment with the original offer, in (the usual) case where it is a single
use offer. We mark it used when it's paid, to avoid a race.

Still asserts that it's the standard size, but makes it a dynamic

a tal object now, so we might as well allocate it here to catch all
the callers).

Changelog-Deprecated: JSON-RPC: `listsendpays` will no longer add `null` if we don't know the `amount_msat` for a payment.
While not directly necessary, it still feeds the `listpays` result, and so we
should pass it along if we can, so we don't have to rely solely on the
`amount_sent` field, which includes the fees.
Reported-by: Rusty Russell <@rustyrussell>
There were no channel updates in my log; because sendonion doesn't know the
actual node_ids or channel_ids, we can't tell gossipd what node/channel it was
so it can no longer remove them on PERM errors.
However, we can tell it the error message so it can apply the update.

Changelog-Added: JSON-RPC: `sendonion` has a new optional `bolt11` argument for when it's used to pay an invoice.

This wasn't important before, but now we have MPP it's good to enforce.
Reported-by: Christian Decker
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This happens to be an edge case with the way we use `sendonion` in
MPP. `sendonion` does not attempt to recover the route even if we supply the
shared secrets (it'd require us to map forwarding channels to the nodes etc),
so `failnode` will always be unset, unless it is the first hop, which gets
stored. This is not a problem if it weren't for the fact that we don't store
the partial route, consisting solely of the channel leading to the first hop,
therefore the assertion that either both are NULL or both aren't fails on the
first hop.
This went unnoticed since with MPP we have more concurrent payments in flight,
increasing the chances of a exhausted first hop considerably.
I noticed the following in logs for tests/test_connection.py::test_feerate_stress:
```
DEBUG 022d223620a359a47ff7f7ac447c85c46c923da53389221a0054c11c1e3ca31d59-chan#1: Failing HTLC 18446744073709551615 due to peer death

```
This is because it reports the (transient) node_failure error, because
our channel_failure message is incomplete. Fix this wart up.

This is what actually lets us pay blinded invoices.
Unfortunately, our internal logic assumes every hop in a path has a
next `short_channel_id`, so we have to use a dummy. This is
sufficient for testing, however.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Note that it's channeld which calculates the shared secret, too. This
minimizes the work that lightningd has to do, at cost of passing this
through.
We also don't yet save the blinding field(s) to the database.

Turns out that unnecessary: all callers can access the feature_set,

Instead of saving a stripped_update, we use the new

This is a common thing to do, so create a macro.
Unfortunately, it still needs the type arg, because the paramter may
be const, and the return cannot be, and C doesn't have a general
"(-const)" cast.

This cleans up the "local failure" callers for incoming HTLCs to hand
an onionreply instead of making us generate it from the code inside
make_failmsg.
(The db path still needs make_failmsg, so that's next).
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-deprecated: Plugins: htlc_accepted_hook "failure_code" only handles simple cases now, use "failure_message".
At the moment, we store e.g. WIRE_TEMPORARY_CHANNEL_FAILURE, and then
lightningd has a large demux function which turns that into the correct
error message.
Such an enum demuxer is an anti-pattern.
Instead, store the message directly for output HTLCs; channeld now
sends us an error message rather than an error code.
For input HTLCs we will still need the failure code if the onion was
bad (since we need to prompt channeld to send a completely different
message than normal), though we can (and will!) eliminate its use in
non-BADONION failure cases.

Using it with a different value to the amount sent causes a crash in 0.8.0,
which is effectively deprecating it, so let's disallow it now.
