We don't cover three common patterns:
1. Optional integers (db_col_u64 has different form from structs)
2. Optional strings.
3. Optional array fields.
But it does neaten and reduce the scope for cut&paste errors in the
common "if not-NULL, tal and assign".

We actually have an assertion that there are no channels remaining when
we delete peers, so this is confusing!
Actually removing the constraint is db-specific and deeply non-trivial.

`struct lightningd` is not completely initialized, so we added a
"migration_context" which only had some of the fields. But we ended
up handing in `struct lightningd` anyway, so I don't think this
complexity is worthwhile.

At the moment only lightingd needs it, and this avoids missing any
places where we do bip32 derivation.
This uses a hsm capability to mean we're backwards compatible with older
hsmds.

e778ebb9af ("wallet: only log broken if we

People are upgrading to 22.11.1 not, and in some configurations like the one
mentioned in the issue, we should

It's not likely but possible that the node's settings will shift btw a
start and an RBF; we persist the setting to the database so we don't
lose it.
Right now holding onto it forever is kind of extra but maybe we'll
reuse the setting for splices? idk.
Should this be a channel type??
technically we don't need this info after the channel opens, but for any
subsequent RBF (and maybe splice?) we need to remember what the
open/accept peer signaled
We didn't actually populate them properly, and the real annotations
are on inputs and outputs.

Rework the logic of the version check used in the

We have a primary key that is spanning the `in_channel_id` and the
`in_htcl_id`. The latter gets set to NULL when the HTLC and channel
gets deleted, so we coalesce with a random large number that is
unlikely to collide for the primary key.
We no longer use offers for "I want to send you money", but we'll use
invoice_requests directly. Create a new table for them, and
associated functions.
The "localofferid" for "pay" and "sendpay" is now "localinvreqid".
This is an experimental-only option, so document the change under
experimental only.

We have to allow them (as otherwise `fees_collected_msat` in getinfo breaks),

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.

contrib/giantnode.py shows we're spending a lot of time looking up
payments by payment_hash: sendpays does it to see if we've already
paid, and bookkeeper does it in listsendpays:

Changelog-Added: Protocol: you can now alter the `htlc_minimum_msat` and `htlc_maximum_msat` your node advertizes.
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 only thing that needs ld->wallet after this is destroy_invoices_waiter (off jsonrpc)
Could not find any other destructors (destroy_*) that need wallet or db access after this.
Any db access would now segfault.
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
Tested by `EXPLAIN QUERY PLAN` on sqlite3; #4901 shows the result from
@whitslack doing a similar partial index on PostgreSQL on his ~1000 chan
node.
ChangeLog-Added: db: Speed up loading of pending HTLCs during startup by using a partial index.
because:
- shutdown_subdaemons can trigger db write, comments in that function say so at least
- resurrecting the main event loop with subdaemons still running is counter productive
in shutting down activity (such as htlc's, hook_calls etc.)
- custom behavior injected by plugins via hooks should be consistent, see test
in previous commmit
IDEA:
in shutdown_plugins, when starting new io_loop:
- A plugin that is still running can return a jsonrpc_request response, this triggers
response_cb, which cannot be handled because subdaemons are gone -> so any response_cb should be blocked/aborted
- jsonrpc is still there, so users (such as plugins) can make new jsonrpc_request's which
cannot be handled because subdaemons are gone -> so new rpc_request should also be blocked
- But we do want to send/receive notifications and log messages (handled in jsonrpc as jsonrpc_notification)
as these do not trigger subdaemon calls or db_write's
Log messages and notifications do not have "id" field, where jsonrpc_request *do* have an "id" field
PLAN (hypothesis):
- hack into plugin_read_json_one OR plugin_response_handle to filter-out json with
an "id" field, this should
block/abandon any jsonrpc_request responses (and new jsonrpc_requests for plugins?)
Q. Can internal (so not via plugin) jsonrpc_requests called in the main io_loop return/revive in
the shutdown io_loop?
A. No. All code under lightningd/ returning command_still_pending depends on either a subdaemon, timer or
plugin. In shutdown loop the subdaemons are dead, timer struct cleared and plugins will be taken
care of (in next commits).
fixup: we can only io_break the main io_loop once
1. db_col_text becomes db_col_strdup, which is what is usually wanted.
2. db_col_short_channel_id becomes db_col_short_channel_id_str, to emphasize
that it stores in string form. Modern versions should store u64.
