This means some files get renamed, and I took the opportunity to clarify
our naming (the *d* is important!)
1. channeld/channel_wire.csv -> channeld/channeld_wire.csv
2. channeld/gen_channel_wire.h -> channeld/channeld_wiregen.h
3. enum channel_wire_type -> enum channeld_wire
4. WIRE_CHANNEL_FUNDING_DEPTH -> WIRE_CHANNELD_FUNDING_DEPTH.

Otherwise valgrind gets upset when we *run* the statements: better
to get a backtrace when we bind, so we can tell which field it is!

We've never hit this, we do check them on insert, and it's slowing

This is an extra safety check for dual funding, where we only want to sign
the inputs we provided!

Changelog-Added: JSON-RPC: `signpsbt` takes an optional `signonly` array to limit what inputs to sign.

This more closely mirrors fundpsbt (which will only select unreserved ones)

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.

We need to remember this in the db (it's a P2WSH for option_anchor_outputs),
and we need to set nSequence to 1 to spend it.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This is best done by passing `struct bitcoin_signature` around instead
of raw signatures. We still save raw sigs to the db, and of course the
wire protocol uses them.

the way we use PSBTs to sign things requires that we have the
scriptpubkey available on the utxo so we can populate the witness-utxo
field with it.
this causes problems if we don't already have the scriptpubkey cached in
the database, as in *some* cases we require a round trip to the HSM to
populate them
to get over this hump, we backfill any and all missing scriptpubkey
information for the utxo's that we hold in our wallet.
this will allow us to clean up the NULL handling of missing
scriptpubkeys.
we're about to add a migration that requires access to the bip32_key
in order to calculate missing scriptpubkeys.
prior to this patch, we don't have access to the bip32 key in the db
migration, as it's set on the wallet but after the db migrations are
run.
here we patch it through so that every migration can access it
fundpsbt forces the caller to manually add their weight * feerate
to the satoshis they ask for. That means no named feerates.
Instead, create a startweight parameter and do the calc for them
internally, and return the feerate we used (and, while we're at it,
the estimated final weight).
This API change is best done now, as it would otherwise have to
be appended as a parameter.

Changelog-Added: ***REMOVE*** JSON-API: `txprepare` returns a psbt version of the created transaction
Technically, they could do this themselves, but it's much nicer to have one
place to do it (and it makes sure we get the required information into the
PSBT, which is actually not entirely accessible through listfunds, as that
doesn't want to consult with the HSM for close outputs).

Changelog-Added: JSON RPC: new low-level coin selection `fundpsbt` routine.
This is the normal case: you only want to reserve inputs which
are not already reserved. This saves you iterating through the
results and unreserving some if you weren't exclusive.

reserveinputs marks UTXOs reserved for 12 hours, so we won't select them
for spending: unreserveinputs marks them available again.

This is a new fundamental routine to obtain UTXOs from the database.
It's not the most efficient approach, as it returns a single UTXO at a

complex by the reservation timeout logic).

PSETs have a bit different requirements. The witness_utxo needs
the asset tag + values, and these should also be added to the PSET
struct separately as well. To do this, we create a new 'init' method for
elements inputs, which takes care of the elements specific things.
This is the only place outside the wallet code where we create
a 'struct utxo', so it makes sense for us to move that logic inside
the wallet.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
It looked like we weren't printing the address on closing outputs.
But we are, because the 'scriptPubkey' field is in the 'outputs' db
table since 0.7.3 (66a47d2761).
So make the logic clearer, and remove a completely bogus comment (UTXOs
with closing_info are definitely spendable!).
We export the json_add_utxos() for future use, too.

These are pulled from wallet/wallet.c, with the fix now that we grind sigs.
This reduces the fees we pay slightly, as you can see in the coinmoves changes.
I now print out all the coin moves in suitable format before we match:
you only see this if the test fails, but it's really helpful.

Changelog-Changed: `txprepare` now prepares transactions whose `nLockTime` is set to the tip blockheight, instead of using 0. `fundchannel` will use `nLockTime` set to the tip blockheight as well.
We were assuming `wallet_channel_insert` that there cannot be a matching peer
if our in-memory representation isn't bound to it (`dbid == 0`). If we then
attempt to create the peer, and we already had one it'd cause a unique
constraint violation. As far as I can tell this could end up happening if we
have an uncommitted channel, and then exited without cleanup (`tal_destructor`
on the uncommitted channel not running). This could then leave the peer in the
DB. This is because the constraint that every peer has at least one channel is
not enforce at DB level, but rather in destructors that may or may not run.
Changelog-Fixed: Fixed a failing assertion if we reconnect to a peer that we had a channel with before, and then attempt to insert the peer into the DB twice.
Changelog-Added: JSON-RPC: new call `signpsbt` which will add the wallet's signatures to a provided psbt
Changelog-Added: JSON-RPC: new call `sendpsbt` which will finalize and send a signed PSBT
Reserve and unreserve wallet UTXOs using a PSBT which includes those
inputs.
Note that currently we unreserve inputs everytime the node restarts.
This will be addressed in a future commit.
Changelog-Added: JSON-RPC: Adds two new rpc methods, `reserveinputs` and `unreserveinputs`, which allow for reserving or unreserving wallet UTXOs
Unused here, but we'll use it in the next commit so that we can always
pass back the effective / used feerate to the caller of `reserveinputs`
This makes opening a channel much easier if we've internally determined
the feerate
