We create ALL_PROGRAMS, ALL_TEST_PROGRAMS, ALL_C_SOURCES and
ALL_C_HEADERS. Then the toplevel Makefile knows which are
autogenerated (by wildcard), so it can have all the rules to clean
them or check the source as necessary.

Changelog-Fixed: build: On some operating systems the postgresql library would not get picked up. `./configure` now uses `pg_config` to locate the headers.
Note that other directories were explicitly depending on the generated
file, instead of relying on their (already existing) dependency on
$(LIGHTNINGD_HSM_CLIENT_OBJS), so we remove that.

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

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.
Required for dual funding where the opener sets it.

This more closely mirrors fundpsbt (which will only select unreserved ones)
but you can turn it off if you want to e.g. rbf in future.

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.

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.

HTLC fees increase (larger weight), and the fee paid by the opener

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).

These keep the struct utxo in sync with the database, explicitly:

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.
