0b680c5f40 lightningd: fix assertion when funding depth changes fast.
We didn't apply the inflight to the channel struct before asserting, so
we can break test_rbf_non_last_mined:

```
lightningd: lightningd/dual_open_control.c:981: dualopend_tell_depth: Assertion `bitcoin_txid_eq(&channel->funding.txid, txid)' failed.

854bda81ac lightningd: don't share funding_depth_cb for non-funding txs.
We use the *same* callback for the funding tx, as well as for inflight dual-funding txs, as well as inflight splice txs.  This is deeply confusing!

Instead, use explicit cbs for splicing and df.  Once they're locked in, use the normal callback.

acc30c0b3f lightningd: split DUALOPEND_OPEN_INIT into DUALOPEND_OPEN_INIT and DUALOPEND_OPEN_COMMITTED.

af6d7c0779 global: thread zero fee option everywhere.
In most cases, it's the same as option_anchor_outputs, but for
fees it's different.  This transformation is the simplest:
pass it as a pair, and test it explicitly.

In future we could rationalize some paths, but this was nice
and mechanical.

1b6ff0b2fc staticbackup: don't use wireaddr_internal.
This is an internal type: it has no API guarantees (indeed, I'm about
to change it, which is how I discovered scb was using it).

Fortunately for every case we care about, it is actually a wireaddr
(in theory the peer can connect locally using a local socket, but this
is mostly for testing and is a very strange setup, and so simply don't
do scb for those).

In this case, the wire encoding is a single byte followed by the
wireaddr, so open-code that in scb_wire.csv for compatibility.

cfa33ce362 lightningd: fix incorrect reuse of dualopend, leading to dev_queryfeerates race
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
         l1.rpc.fundchannel(l2.info['id'], amount, request_amt=amount,
                            feerate='{}perkw'.format(feerate),
