when anchors are enabled) not an anchor output!

Drop try_get_feerate() in favor of explicit feerate_for_deadline() and
smoothed_feerate_for_deadline().
This shows us everywhere we deal with old-style feerates by names.
`delayed_to_us` and `htlc_resolution` will be moving to dynamic fees,
so deprecate those.
Note that "penalty" is still used for generating penalty txs for
watchtowers, and "unilateral_close" still used until we get zero-fee
anchors.
Changelog-Added: JSON-RPC: `feerates` `estimates` array shows fee estimates by blockcount from underlying plugin (usually *bcli*).
Changelog-Changed: JSON-RPC: `close`, `fundchannel`, `fundpsbt`, `multifundchannel`, `multiwithdraw`, `txprepare`, `upgradewallet`, `withdraw` `feerate` (`feerange` for `close`) value *slow* is now 100 block-estimate, not half of 100-block estimate.
Changelog-Deprecated: JSON-RPC: `close`, `fundchannel`, `fundpsbt`, `multifundchannel`, `multiwithdraw`, `txprepare`, `upgradewallet`, `withdraw` `feerate` (`feerange` for `close`) expressed as, "delayed_to_us", "htlc_resolution", "max_acceptable" or "min_acceptable". Use explicit block counts or *slow*/*normal*/*urgent*/*minimum*.

We'll want this, as lightningd will want to produce htlc txs based on
what it's told from onchaind, so we need a lower-level accessor.

We previously used WIRE_HSMD_SIGN_DELAYED_PAYMENT_TO_US,
WIRE_HSMD_SIGN_REMOTE_HTLC_TO_US, WIRE_HSMD_SIGN_PENALTY_TO_US and
WIRE_HSMD_SIGN_LOCAL_HTLC_TX which allow onchaind to sign txs,
but only for its specific channel.
We now want lightningd to sign these, but it's not bound to a specific
channel. So let's add variants that don't require that.
We are also now explicit about *what input* to sign. It's always zero
for now, but future combinations may change that.

Libwally update breaks compatibility, so
we do this in one large step.
Changelog-Changed: JSON-RPC: elements network PSET now only supports PSETv2.
Changelog-Added: JSON-RPC: PSBTv2 supported for fundchannel_complete, openchannel_update, reserveinputs, sendpsbt, signpsbt, withdraw and unreserveinputs parameter psbt, openchannel_init and openchannel_bump parameter initialpsbt, openchannel_signed parameter signed_psbt and utxopsbt parameter utxopsbt
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.

Changelog-Added: Protocol: we now always double-check bitcoin addresses are correct (no memory errors!) before issuing them.

I do not know if this is a solution because I do not know
when I can parse a node announcement for a node that
it is not longer in the gossip map.
So, I hope this is just usefult for @rustyrussell

Changelog-EXPERIMENTAL: Protocol: dual-funding spec changed in incompatible ways, won't work with old versions (but maybe soon with Eclair!!)
When a channel open fails, we use tx-abort instead of warning/error.
This means that the peer won't disconnect! And instead when a new
message arrives, we'll need to rebuild the dualopend subd (if missing).
Makes opens a bit easer to retry (no reconnect needed), as well as keeps
the connection alive for other channels we may have with that peer.
Changelog-Changed: Experimental-Dual-Fund: open failures don't disconnect, but instead fail the opening process
Also, put the "added" lines in the request schemas for new commands:
this doesn't do anything (yet?) but it keeps `make schema-added-check` happy.

Though BOLT 7 says a channel may be pruned when one side becomes inactive
and fails to refresh their channel_update, in practice, the
channel_announcement can be difficult to recover if deleted entirely.
Here the channel_announcement is tagged as zombie such that gossip_store
consumers may safely ignore it, but it may be retained should the channel
come back online in the future. Node_announcements and channel_updates may
also be retained in such a fashion until the channel is ready to be
resurrected.
Changelog-Fixed: Pruned channels are more reliably restored.
Fixes d9fed06b90:
```
common/bolt11.c:868:31: error: format specifies type 'size_t' (aka 'unsigned long') but the argument has type 'u64' (aka 'unsigned long long') [-Werror,-Wformat]

Other than textual changes, this does:
1. Ensures we put total_amount_msat in onion final hop (reported by @t-bast).
2. Require that they put total_amount_msat in onion final hop.
3. Return `invalid_onion_blinding` exactly as defined by the spec (i.e. less
aggressive when we're the final hop) (also reported by @t-bast, but I already
knew).
