This allows us to mark an offer used when an invoice derived from it
is paid, and importantly, avoid any other invoices for the offer being

Needed for v2 of channel opens, where the minimum weight is 110; a
'simple utxo' (sig + key) weighs in at 107, so we a need a way to
establish a floor for this case.
Changelog-Added: JSON-RPC: fundpsbt/utxopsbt have new param, `min_witness_utxo`, which sets a floor for the weight calculation of an added input
Avoids much cut & paste. Some tests don't need any of it, but most
want at least some of this infrastructure.

This adds a `state_change` 'cause' to a channel.
A 'cause' is some initial 'reason' a channel was created or closed by:
/* Anything other than the reasons below. Should not happen. */
REASON_UNKNOWN,
/* Unconscious internal reasons, e.g. dev fail of a channel. */
REASON_LOCAL,
/* The operator or a plugin opened or closed a channel by intention. */
REASON_USER,
/* The remote closed or funded a channel with us by intention. */
REASON_REMOTE,
/* E.g. We need to close a channel because of bad signatures and such. */
REASON_PROTOCOL,
/* A channel was closed onchain, while we were offline. */
/* Note: This is very likely a conscious remote decision. */
REASON_ONCHAIN
If a 'cause' is known and a subsequent state change is made with
`REASON_UNKNOWN` the preceding cause will be used as reason, since a lot
(all `REASON_UNKNOWN`) state changes are a subsequent consequences of a prior
cause: local, user, remote, protocol or onchain.

We need the PSBT to create the finalized tx from once the peer's
tx_signatures are received. Since we're passing the PSBT, we no longer
need the secondary message to be passed, as it was derived from the
PSBT.
Also removes now unused witness serialization code
We need this for dual funding, since the interactive tx construction
protocol requires the full tx to send places. We add it to all PSBTs (if
we have it), here
This adds an environment variable $NO_PYTHON check to Makefiles so that:
- It checks and runs into an defined error instead of some python hickup:
`ModuleNotFoundError: No module named 'mako'`
- makes it possible to manually export this environment variable NO_PYTHON=1
to run the same testcase that travis is running on job 1 which causes
so much pain ;)

We force use of tal_wally_start/tal_wally_end around every wally
allocation, and with "end" make the caller choose where to reparent
everything.
This is particularly powerful where we allocate a tx or a psbt: we
want that tx or psbt to be the parent of the other allocations, so
this way we can reparent the tx or psbt, then reparent everything
else onto it.
Implementing psbt_finalize (which uses a behavior flag antipattern)
was tricky, so I ended up splitting that into 'psbt_finalize' and
'psbt_final_tx', which I think also makes the callers clearer.

dual funding needs the max-witness-len and utxo fields set for every
input. we should add them when we create a 'fundpsbt', so that every
psbt that c-lightning generates is dual-funding ready
v2 of channel establishment, in the accpeter case, now sends 2 messages
to our peer after saving the information to disk (our commitment
signatures and our funding transaction signatures)
v2 channel open uses a different method to derive the channel_id, so now
we save it to the database so that we dont have to remember how to
derive it for each.
includes a migration for existing channels
fundpsbt / utxopsbt create a (typically) output-less PSBT,
however for elements we require the fees to be encapsulated in an
output.
this patch updates fundpsbt / utxopsbt to add a fee output for elements
transactions. includes test updates.
Fixes#3998
We defer the notification to gossipd till the end of the spends. By itself not
a huge change, but it allows us to later migrate to doing updates blindly and
using the DB as our ground truth. It also allows us to simplify the
`wallet_outpoint_spend` semantics to not return two values in the next commit.
We're going to want this for bolt13 formation as well.
As a result of reworking the logic into "candidate selection" then
"route hint selection", we need to change the way round-robin works.
We use a simple incrementing index now.

This removes the reservation cleanup at startup, too, now they're all
using 'reserved_til'.
This changes test_withdraw, since it asserted that outputs were marked
spent as soon as we broadcast a transaction: now they're reserved until
it's mined. Similarly, test_addfunds_from_block assumed we'd see funds
as soon as we broadcast the tx.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Changed: JSON-RPC: `withdraw` now randomizes input and output order, not BIP69.
Marking spent means if the transaction doesn't confirm for some
reason, the user will need to force a rescan to find the funds. Now
we have timed reservations, reserving for (an additional) 12 hours
should be sufficient.
We also take this opportunity (now we have our own callback path)
to record the tx in the wallet only on success.

Changelog-Added: JSON-RPC: New low-level command `utxopsbt` to create PSBT from existing utxos.
It's *possible* to do this using various RPC calls, but it's
unfriendly:
1. Call getinfo to get the current block height.
2. Call listfunds to map the UTXOs.
3. Create the PSBT and hope you get all the fields correct.
Instead, this presents an interface just like `fundpsbt`, with identical
returns.
I think it's different enough to justify a new command (though it
shares much internally, of course).
In particular, it's now quite simple to create a command which uses
specified utxos, and then adds more to meet any shortfall.
