You can now activate dual-funded channels using the
`--experimental-dual-fund` flag
Changelog-Changed: Config: `--experimental-dual-fund` runtime flag will enable dual-funded protocol on this node
Otherwise, we might find an address other than the one given and
the user might think that address worked.

Changelog-Deprecated: JSON-RPC: `fundchannel_complete` `txid` and `txout` parameters (use `psbt`)
Users have no idea what they would pay for unilateral closes.
At least this gives them a clue!

Changelog-Added: JSON-RPC: `listpeers` now shows latest feerate and unilaral close fee.

They need to specify fees to get a channel before this, but it's possible.
The test revealed no surprises (other than the last change).

Saves a great deal of confusion for regtest users.

Changelog-Changed: JSON-RPC: If bitcoind won't give a fee estimate in regtest, use minimum.
Nested `with` exception checks don't work; fix flakes i'm seeing with
valgrind causing failures because blockchain not up to date when
`fundchannel` called.
It was using a trick to only shut down the first node, and forgetting
about the others. This could lead to processes not being stopped
correctly and to test failures because the directory isn't cleaned up
correctly.
Now we use the executor to shut as many nodes as possible in parallel.
Since we turned many errors into warnings, we want our tests to fail
when they happen unexpectedly. We make WARNING clear in the strings
we print, too, to help out.

And make all the callers choose which one. In general, I prefer warn,
which lets them reconnect and try again, however some places are either
stated that they must be errors in the spec itself, or in openingd
where we abandon the channel when we close the connection anyway.

Changelog-Changed: Protocol: we now send warning messages and close the connection, except on unrecoverable errors.
If we're quick (or the node is slow) we end up reconnecting before our
counterparty has realized the state transition, resulting in an
unexpected re-establish.
There's a case where a dropped funding_locked will result in the peer
moving onto channeld, while we stay in dualopend. As we haven't
received their funding_locked, we retransmit tx_sigs, which channeld
will need to handle.
With the patch the peer drops it on the floor; the peer will resend
funding_locked on reconnect, which will correctly advance us to
channeld and CHANNELD_NORMAL
If we're already attempting to connect to a peer, we would ignore
new connection requests. This is problematic if your node has bad
connection details for the node -- you can't update it while inflight.
This patch appends new connection suggestions to the list of connections
to try.
