option_will_fund changes the to_remote/to_local commitment tx
outputs by altering the CSV lock for leased channels.
We need to grind/scan for these outputs now, provided the defaults don't
work.
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)
If there's a rate-card for liquidity, we don't know about it until
after startup (the plugin *should* call us at init to tell us what their
current rates are)
Using a 'feestep' is more restrictive than you'd want, instead we
enforce that the next feerate must be at least 1/64th more than the
last, but put no upper limit on it
Includes update to lnprototest changes

Changelog-EXPERIMENTAL: Protocol: Replaces init_rbf's `fee_step` for RBF of v2 opens with `funding_feerate_perkw`, breaking change
We were getting off-by-one for the total amount that the change is for,
since it rounds the fee *down*, independent of the total weight of the
entire tx.
We fix this by using the diff btw the fee of the total weight (w/ and
w/o the change output)
Setting VALGRIND=1 actually does nothing here; reduce it to two cases,
covering gcc and clang, sqlite3 and postgres.

This adds a `u32 checksum` field to the plugin struct that is used
to identify if a plugin is outdated and needs to be restarted on `rescan`.
Note: Only affects non-important plugins.
Changelog-Added: Plugin: Restart plugin on `rescan` when binary was changed.
So far we could not reach non-publicly reachable nodes with the
keysend command since we couldn't compute a route to them. With this
change we can add some routehints that we may have gotten from an
address book or a previous invoice, and make it more likely that we
can reach the destination.
Changelog-Added: keysend: `keysend` can now reach non-public nodes by providing the `routehints` argument if they are known.
Incoming HTLCs are rejected by the HTLC logic if the payload contains
an even type that `lightningd` doesn't recognize. This is to prevent
us from accidentally accepting a payment that has extra semantics
attached (for example if we get a keysend payment and don't know what
to do with the TLV field containing the message we should reject it,
otherwise the overall semantics of the message delivery fail).
Enable non-dev builds to send custom messages.
Preserves 'dev-' for compat-enabled builds.
Changelog-Changed: JSON-RPC: moved dev-sendcustommsg to sendcustommsg
This is in preparation for removing support (next release?).
Changelog-Changed: Protocol: We now assume nodes support TLV onions (non-legacy) unless we have a node_announcement which says they don't.

In fact, we make it compulsory, which means if you don't understand it
you'll hang up on us!
Add some logging for that in future.
Changelog-Changed: Protocol: All new invoices require a payment_secret (i.e. modern TLV format onion)
Changelog-Changed: Protocol: We can no longer connect to peers which don't support `payment_secret`.

This makes it easier to access (rather than decoding bolt11).
Changelog-Added: JSON-RPC: `invoice` now outputs explicit `payment_secret` it its own field.
