We use the saved previous outputs (plus maybe some new ones?) to build a
psbt for an RBF request.
RBFs utxo reuse is now working so we can unfail the test (and update
it to reflect that the lease sticks around through an RBF cycle).
Changelog-Fixed: Plugins: `funder` now honors lease requests across RBFs
We have them split over common/param.c, common/json.c,
common/json_helpers.c, common/json_tok.c and common/json_stream.c.
Change that to:
* common/json_parse (all the json_to_xxx routines)
* common/json_parse_simple (simplest the json parsing routines, for cli too)
* common/json_stream (all the json_add_xxx routines)
* common/json_param (all the param and param_xxx routines)

This code was buggy: handing "1000" as a parameter to
min_their_funding_msat, don't turn that into "1000sat"!
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
We had json_add_amount_msat_only(), which was designed to be used to
print out msat fields, if we had sats.
However, we misused it, so split it into the three different cases:
1. json_add_amount_sat_msat: We are using it correctly, with a field called
xxx_msat.
2. json_add_amount_sats_deprecated: We were using it wrong, so deprecate
the old field and create a new one which does end in _msat.
3. json_add_sats: we were using it to hand sats as a JSON parameter to an
interface, where "XXXsat".

Make it always a number; this makes the JSON request specification
simpler. We allowed a number since v0.10.1.
(reserve=True is the default anyway, so usually it can be omitted:
reserve=False becomes reserve=0).
Changelog-Deprecated: JSON-RPC: `fundpsbt`/`utxopsbt` `reserve` must be a number, not bool (for `true` use 72/don't specify, for `false` use 0). Numbers have been allowed since v0.10.1.
Changelog-Experimental: option `--lease-fee-base-msat` renamed to `--lease-fee-base-sat`
Changelog-Experimental: option `--lease-fee-base-msat` deprecated and will be removed next release
We always allocate a new `struct command` when we get a full JSON
object from stdin:
b2df01dc73/plugins/libplugin.c (L1229-L1233)
If it happens to be a notification, we pass the `struct command` to
the handler, and not free it ourselves:
b2df01dc73/plugins/libplugin.c (L1270-L1275)
There are only nine points in `plugins/libplugin.c` where we `tal_free`
anything, and only one of them frees a `struct command`:
b2df01dc73/plugins/libplugin.c (L224-L234)
The above function `command_complete` is not appropriate for
notification handlers; the above function sends out a response
to our stdout, which a notification handler should not do.
However, as-is, it does mean that notification handling leaks
`struct command` objects, which can be problematic if we ever
have future built-in plugins which are significantly more
dependent on notifications.
This commit changes notification handlers to return
`struct command_result *`, because possibly in the future
notification handlers may want to perform `send_outreq`, so we
might as well use our standard convention for callbacks, and
to encourage future developers to check how to properly
terminate notification handlers (and free up the
`struct command`).
We also now provide a `notification_handled` function which a
notification handler must eventually call, as well as a
`notification_handler_pending` which is just a snowclone of
`command_still_pending`.

Documentation for the funderupdate command on the funder plugin.
Realized we were missing the "leases_only" in the output; also adds
'_msat' to msat denominated outputs so they're parsed correctly by our
python bindings (also matches our naming conventions)
Changelog-EXPERIMENTAL: funder: `funderupdate` command to view and update params for contributing our wallet funds to v2 channel openings. Provides params for enabling `option_will_fund`.
If there's no plugin currently in place, we simply won't return any
funding at all, in which case we'd expect them to handle however
they want. (our implementation would fail the open, as we only accept
opens that have at least as much as we've requested provided)
We need to know what the lease we're expecting is. To do this
we pass around the hex encoded portion of the wire format.
We can use this passed in expected lease rates to confirm that the peer
is, in fact, using the same rates as what we have currently.
Changelog-Added: JSON-RPC: fundchannel, multifundchannel, and openchannel_init now accept a 'compact_lease' for any requested funds
When a request comes through, we forward it over to the funder who
uses the currently set policy to figure out how to handle it.
Includes small update to the policy engine which decides whether or not
to fund a request.
Changelog-Experimental: Plugins: `openchannel2` hook now includes optional fields for a channel lease request
Implement support for liquidity ads in `funder` plugin. We set the
command line options for the leases, as well as sending the updated ads
to lightningd (who then passes them through to gossipd)
Changelog-Added: Plugins: `funder` plugin now has new command `funderupdate` which will show current funding configuration and allow you to modify them
Behold! An immaculately concepted plugin for configuring your node to do
amazing things*
*fund channel open requests
Changelog-Added: Plugins: Add `funder` plugin, which allows you to setup a policy for funding v2 channel open requests. Requres --experimental-dual-fund option
