Normally, we'd use the delete_columns function to remove the old
`short_channel_id` string field, *but* we can't do that for sqlite, as
there are other tables with references to it. So add a FIXME to do
it once everyone has upgraded to an sqlite3 which has native support
for column deletion.

This one directly contains the scids of the channels involved, not
references, so can outlive the channels. As a side-effect, however,
it now never lists `payment_hash`. Having it listed (via join) is not
possible as it is a *string* in the channels table, and difficult
anyway because of channel aliases.

They're not logically connected: we can know where they wanted to
go, but we didn't send it.
Where possible, it's the scid *they asked for*; otherwise, it's the
scid or fallback to the alias, but do this in the *caller*, not by
overriding inside wallet_forwarded_payment_add.

Not only can the outgoing edge be a zeroconf channel, it can also be
the incoming channel. So we revert to the usual trick of using the
local alias if the short_channel_id isn't known yet.
We use the LOCAL alias instead of the REMOTE alias even though the
sender likely used the REMOTE alias to refer to the channel. This is
because we control the LOCAL alias, and we keep it stable during the
lifetime of the channel, whereas the REMOTE one could change or not be
there yet.
`alias_local` is generated locally and sent to the peer so it knows
what we're calling the channel, while `alias_remote` is received by
the peer so we know what to include in routehints when generating
invoices.

We need to stash/save the amount of the lease fees on a leased channel,
we do this by re-using the 'push' amount field on channel (which is
technically correct, since we're essentially pushing the fee amount to
the peer).
Also updates a bit of how the pushes are accounted for (pushed to now
has an event; their channel will open at zero but then they'll
immediately register a push event).
Leases fees are treated exactly the same as pushes, except labeled
differently.
Required adding a 'lease_fee' field to the inflights so we keep track of
the fee for the lease until the open happens.
If we initialized the payment, the fees are the entire fee-chain
(final hop amount - starting hop amount)
If it's a payment we routed, the fees are the diff between the
inbound htlc and the outbound (net gain by this routing)
Added to database so data persists nicely.
The old model of coin movements attempted to compute fees etc and log
amounts, not utxos. This is not as robust, as multi-party opens and dual
funded channels make it hard to account for fees etc correctly.
Instead, we move towards a 'utxo' view of the onchain events. Every
event is either the creation or 'destruction' of a utxo. For cases where
the value of the utxo is not (fully) debited/credited to our account, we
also record the output_value. E.g. channel closings spend a utxo who's
entire value we may not own.
Since we're now tracking UTXOs onchain, we can now do more complex
assertions about the onchain footprint of them. The integration tests
have been updated to now use more 'chain aware' assertions about the
ending state.
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.

Closes: #4901

since PR #3867 utxos are unreserved by height, destroy_utxos and
related functions are not used anymore so clean them up also
However free(ld->jsonrpc) still needs to happen before free(ld) because its
destructors need list_head pointers from ld
This simplistically maps names to numbers, eg:

If we're over the dust limit, we fail it immediatey *after* commiting
it, but we need a way to signal this throughout the lifecycle, so we add
it to htlc_in struct and persist it through to the database.
If it's supposed to be failed, we fail after the commit cycle is
completed.
To reduce the surface area of amount of a channel balance that can be
eaten up as htlc dust, we introduce a new config
'--max-dust-htlc-exposure-msat', which sets the max amount that any
channel's balance can be added as dust
Changelog-Added: config: new option --max-dust-htlc-exposure-msat, which limits the total amount of sats to be allowed as dust on a channel
When doing things like `waitsendpay` without specifying the `groupid`

This means remembering the connection direction. We also use the address to try

We need to know if they've sent us their sigs message yet. Ideally, we'd

This reverts commit c239a7161b.
The goal of c239a716 was to reduce the memory footprint of our
internal UTXO set tracking, and testing against the sqlite3 backend

roundtrips to the DB server with postgres was having a considerable
performance impact, and backups would also bloat due to the increased
number of queries.

regression.

We defer the notification to gossipd till the end of the spends. By itself not
a huge change, but it allows us to later migrate to doing updates blindly and

This removes the reservation cleanup at startup, too, now they're all
using 'reserved_til'.

We were assuming `wallet_channel_insert` that there cannot be a matching peer
if our in-memory representation isn't bound to it (`dbid == 0`). If we then
attempt to create the peer, and we already had one it'd cause a unique
constraint violation. As far as I can tell this could end up happening if we
have an uncommitted channel, and then exited without cleanup (`tal_destructor`
on the uncommitted channel not running). This could then leave the peer in the
DB. This is because the constraint that every peer has at least one channel is
not enforce at DB level, but rather in destructors that may or may not run.
Changelog-Fixed: Fixed a failing assertion if we reconnect to a peer that we had a channel with before, and then attempt to insert the peer into the DB twice.
