It's not all that rare to do these operations, and requiring annotations
for it is a little painful.

Changelog-Changed: JSON-RPC: `delinvoice` will now report specific error codes: 905 for failing to find the invoice, 906 for the invoice status not matching the parameter.
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.
We don't preserve detailed asset information at the moment, so provide a
way to convert from a sat to an amount_asset struct.
We also need a way to convert from an 'amount_asset' to a 'value' for
elements, which for explicit (i.e. non-blinded) asssets is a 0x01 prefix
plus the big-endian encoded value.
If you used feerate=750, instead of feerate="750" it didn't work, since the
token is not a string.

Changelog-Fixed: JSON RPC: `withdraw` and `txprepare` `feerate` can be a JSON number.
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.

libwally's API requires us to pass in NULL pointers if the array size is
zero, so we update our array from wire-er to comply with this
requirement
[ Added fix to avoid tal_resize() of NULL -- RR ]
Our existing coin_moves tracking logic assumed that any tx we had an
input in belonged to *all* of our wallet (not a bad assumption as long
as there was no way to update a tx that spends our wallets)
Now that we've got `signpsbt` implemented, however, we need to be
careful about how we account for withdrawals. For now we do a best guess
at what the feerate is, and lump all of our spent outputs as a
'withdrawal' when it's impossible to disambiguate
The main change here is that the previously-optional open/accept
fields and reestablish fields are now compulsory (everyone was
including them anyway). In fact, the open/accept is a TLV
because it was actually the same format.

Changelog-Removed: protocol: support for optioned form of reestablish messages now compulsory.

We're not using the change_outnum for withdraw tx's (and the way
we were calculating it was broken as of the addition of 'multiple
outputs'). This removes the change output knowhow from withdraw_tx
entirely, and pushes the responsibility up to the caller to
include the change output in the output set if desired.
Consequently, we also remove the change output knowhow from hsmd.
Update the `bitcoin_tx_add_input` interface to accept a witness script
and or scriptPubkey.
We save the amount + witness script + witness program (if known) to
the PSBT object for a transaction when creating an input.
Spec is wrong (it says it should be compulsory), and Eclair doesn't set it
at all, leading to an error when they send their announcement_signatures.

Changelog-changed: large-channels: negotiate successfully with Eclair nodes.
It returns NULL, so you can simply `return fromwire_fail(...)`
if you want to return NULL in this case. Use that more.

Since we now over-write the wally malloc/free functions, we need to do
so for tests as well. Here we pull up all of the common setup/teardown
logic into a separate place, and update the tests that use libwally to
use the new common_setup core
Changelog-None
We did this originally because these types are referred to in the bolts, and we
had no way of injecting the correct include lines into those. Now we do, so
there's less excuse for this.
