This matters: if we connected, the address is probably usable for future connections.
But if they connected, the port is probably not (but the IP address may be).
Changelog-Added: JSON-RPC: `connect` returns "direction" ("in": they iniatated, or "out": we initiated)
Changelog-Added: plugins: `peer_connected` hook and `connect` notifications have "direction" field.

If gossip_store is an incorrect version, we will recreate it: with an incorrect
version! This means we never get persistent gossip, *and* the pay plugin will
fail to map the gossip_store. Everyone will be sad.

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
This was flaky because sometimes we'd generate blocks before the funding
transaction reached the mempool.
If we wait until it's in, it works as expected.
[ Neatened to use wait_for_mempool arg --RR ]
We updated the "UNKNOWN TYPE channel_id" -> the actual channel id;
the reason for why the error fails shouldn't be restrictive (we just
know that it fails)
clang 10.0.0 (erroneously?) claims an enum_side cannot be >= NUM_SIDES.
Make it clear that we're testing the raw u8 for validity.

As @fiatjaf points out we were notifying before we were actually set
on accepting, since the hook could also still reject. Switched them
around does and calling the notification only once it's been decided
is the correct thing to do.
Changelog-Fixed: plugin: The `invoice_payment` notification was being sent before the hook was called, which could still abort it.

There is little point in faking a self-payment, but we should also not
crash :-)
Fixes#4438
Changelog-Fixed: keysend: Keysend returns an error when a self-payment is requested
In the case of failures/disconnects between dualopend receiving the sigs
and the main man disconnecting (as can happen using the testing
disconnects), failing to forward their sigs over to lightningd can
result in the channel never progressing from DUALOPEND_OPEN_INIT
to DUALOPEND_AWAITING_LOCKIN.
Always re-relay.
There are perfectly valid reasons for us to not have a command on return
(something went boom while sending them our sigs and we've now gotten
their sigs during a reconnect and subsequently broadcast the tx)
This can result in us logging a warning if we've 1) dropped their sigs
response, 2) only us (the opener) added inputs, 3) and we broadcast on
their reconnect (when they retransmit their sigs)
Otherwise, we might find an address other than the one given and
the user might think that address worked.

We try not to exceed either side, but the spec still allows them to

Changelog-Deprecated: JSON-RPC: `fundchannel_complete` `txid` and `txout` parameters (use `psbt`)
In particular, txprepare gives us a nice way to get a valid PSBT for
testing.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: JSON-RPC: `txprepare` and `withdraw` now return a `psbt` field.
Requiring the user to calculate the txid of the PSBT is a horrible, bad,
no-good idea.
Doesn't deprecate yet, so I can test that this path works while
multifundchannel still uses it.

Changelog-Added: JSON-RPC: `fundchannel_complete` takes a psbt parameter.
Changelog-Added: lightningd: experimental-shutdown-wrong-funding to allow remote nodes to close incorrectly opened channels.
Changelog-Added: JSON-RPC: close has a new `wrong_funding` option to try to close out unused channels where we messed up the funding tx.

It's not unheard of for people to give the wrong funding tx to us,
getting their funds stuck. Interestingly, we can allow mutual close
using a different txid and output number as long as they (solely)
funded the channel, and the channel hasn't been used.
This defines a "play area" feature to do just that.
