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.
Fixes: #4416 (at least for future users!)

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.

We scan config.vars to figure out if you configured developer on or off.
If it's on, we add the dev-only options to the config.

Previously this ported errors around as JSON. A nicer thing to do is to
deconstruct/reconstruct it; this also allows us to create our own errors
from within the multifundchannel family.
There's a version of this that keeps the PSBT in memory and does some
fancy addition/subtraction of unuseable parts for the v2's, however
it's much easier and simpler to simply error on the peer and re-start
from the very beginning.
This only works if we haven't gotten commitments from the peer yet (in
fact either method would only work if we haven't got commitments from
the peer yet), so if we've got commitments from them we simply mark them
as failed an go again.
In a perfect world, we'd remember what inputs we used last time, and
reuse those again on the re-attempt, which would pefectly guarantee both
that the failed opens (ones w/ commitments exchanged) would be canceled
after this completes (and we could re-try the failed again).
As it is, this is not perfect. It is, however, servicable.
Allows us to clean up an in-progress open that we won't be completing
Changelog-Added: EXPERIMENTAL JSON-RPC: Permit user-initiated aborting of in-progress opens. Only valid for not-yet-committed opens and RBF-attempts
The `rbf_channel` hook uses `our_funding_msat`, which is a nicer
and more easily understood than the `openchannel2`
`accepter_funding_msat`.
This updates the `openchannel2` hook to use the same nomenclature as
`rbf_channel`.
We were automatically falling back to bolt12 decoding, clobbering the
fail message. Ultimately resulting in confusing error
messages (expected prefix lni but got lnbtrc). Now we first determine
which decoding we're trying to do, and then only decode accordingly.
Changelog-Fixed: pay: Report the correct decoding error if bolt11 parsing fails.
We were not aborting if we had routehints, even though all routehints
may have been filtered out.
Changelog-Fixed: pay: `pay` will now abort early if the destination is not reachable directly nor via routehints.
We would happily spin on attempts that are doomed to fail because we
don't know the entrypoint. Next up: remove routehints whose
entrypoints are known but unreachable.
