Changelog-EXPERIMENTAL: JSON-RPC: `listtransactions` `channel` and `type` field removed at top level.
Rework the logic of the version check used in the
database migration, and make sure
that it is full functional to avoid confusion
at release time.
Changelog-Fixed: database: Correctly identity official release versions for database upgrade.

This was reported, but the channel was closed. So however we ended
up with a duplicate, we're no *worse* off than we were before migration?

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.

Changelog-EXPERIMENTAL: JSON-RPC: `pay` and `sendpay` `localofferid` is now `localinvreqid`.
Changelog-Changed: JSON-RPC: `listfunds` now lists coinbase outputs as 'immature' until they're spendable
Changelog-Changed: JSON-RPC: UTXOs aren't spendable while immature
We have to allow them (as otherwise `fees_collected_msat` in getinfo breaks),
but it means that actually, in_htlc_id might be missing in listforwards
(also, out_htlc_id might be missing, which we didn't catch before).

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:
```
- 94.52% 0.00% lightningd lightningd [.] read_json
- 94.52% read_json
- 94.48% parse_request
- 94.46% plugin_hook_call_rpc_command

- 94.46% command_exec

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.

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
This is particularly useful after our recent field deletion:
before: 362,573,824 bytes
after: 124,190,720 bytes

Changelog-Changed: db: removal of old HTLC information and vacuuming shrinks large lightningd.sqlite3 by a factor of 2-3.
And initialize max to current height max when htlcs are already dead.
Turns out (thanks CI!) that MAX() of multiple columns is GREATEST() in
Postgres. That's clearer (MAX is used elsewhere for single columns),
so translate on the sqlite3 side.

After some discussion with @shesek, and my own usage, we agreed that
a more comprehensive interface, which explicitly supports grouping,
is desirable.
Thus keys are now arrays, with the semantic that a key is either a
parent or has a value, never both.
For convenience in the JSON schema, we always return them as arrays,
though we accept simple strings as arguments.
