Rather than take the first two from peers with committed channels, use
the most common address given by at least 2 peers, and accept the majority
from non-committed peers if there are no committed peers.
This works well with the node_announcement rework, which waits until
everyone has a chance to connect before creating the node_announcement.

We use parameterization here. The old `anchor_expected()` was for
non-zero-fee anchors, and have bitrotted so there are some other
changes as well.
Unfortunately, all the anchor accounting seems to be broken, but I
cannot understand these tests at all. I had to simply disable them
for now.

CI hit this issue where it would get a tx_abort in fundchannel. This
happens when the dualopend we use to query the feerates has not exited
yet (it waits for the tx_abort reply), and we mistakenly reuse it.
With multi-channel support, this is wrong: just run another one and it
all Just Works.
This means we need to rework our dual_open_control.c logic, since it
would previously create an unsaved channel then not clean up if
something went wrong.
Most people will never try to negotiate opening multiple channels to
the same peer at the same time (vs. having an established channel and
opening a new one), so this case is a bit weird.
```
rates = l1.rpc.dev_queryrates(l2.info['id'], amount, amount)
# l1 leases a channel from l2

We always call channel_fail_transient() on all channels when a peer
connects, to clean up any previous connections. However, when
we startup, this channel doesn't have an owner yet, resulting in
a fairly weird INFO level message.

Changelog-Fixed: `lightningd`: don't log gratuitous "Peer transient failure" message on first connection after restart.
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
