This merge was a bit tricky, since in Elements the witnesses are not
part of the transaction inputs themselves. This merge should be reviewed
carefully.
The external input test with specifying input weight would make a
pessimistic estimate of the input weight. However this would result in a
test failure as it is sometimes too pessimistic when an ECDSA signature
ends up being smaller than usual. To correct this, we can calculate the
input weight more accurately.
Added tests to rpc_fundrawtransaction, wallet_send, and rpc_psbt that
test that external inputs can be spent when input weight is provided.
Also tested that the input weight overrides any calculated weight.
Additionally, rpc_psbt's external inputs test is cleaned up a bit to be
more similar to rpc_fundrawtransaction's and avoid potential pitfalls
due to non-deterministic coin selection behavior.
The previous diff touched most files in ./test/, so bump the headers to
avoid having to touch them again for a bump later.

Surprisingly easy to do. Almost all of the diff resolution was mechanically
* replacing boost::variant with std::variant
* replacing Optional with std::optional
* then replacing `nullopt` with `std::nullopt`
* updating the RPC functions for the new RPCArg::Default type
* update the tests/ directory to make new (since 22) tests use arrays for
createrawtransaction outputs
* other ad-hoc changes to function parameters etc (not too many of these)
I had to "really" change the code in PrecomputePSBTData, which was introduced
in 22.0 and affected by PSET, but this function was like 8 lines long so it
was easy.
Reviewing the diff may be a bit difficult because of the mix of mechanical
changes and ad-hoc things. Probably the most straightforward thing to do
is to redo the merge, `sed -i` to fix the boost::variant and Optional stuff,
then diff the remaining conflicts against this commit.
TODO: grep for `blindpsbt` and you will see that this RPC is still referenced
in documentation and help text even though it was deleted. Need to fix this
in 0.21 in a separate PR.
I hacked up rpc_fundrawtransaction.py a little bit because our `get_address`
method here depends on nobody having called `createwallet` on a particular
node ... the "correct" fix for this would be to redo the Elements changes
to this functional test for the 0.20+ createwallet changes, but because
there will be big future changes to this test (in Elements #900 (PSET))
I did the quick/hacky thing, and will defer cleanups to a separate
post-rebase PR.
11d6459b6e rpc: include_unsafe option for fundrawtransaction (t-bast)
Pull request description:
Allow RPC users to opt-in to unsafe inputs when funding a raw transaction.
Applications that need to manage a complex RBF flow (such as lightning nodes using anchor outputs) are very limited if they can only use safe inputs.
I also added this option to `send` and `walletcreatefundedpsbt` who internally delegate to `fundrawtransaction`.
Fixes#21299

1) add a new sane "address" field (for outputs that have an
identifiable address, which doesn't include bare multisig)
2) with -deprecatedrpc: leave "reqSigs" and "addresses" intact
(with all weird/wrong behavior they have now)
3) without -deprecatedrpc: drop "reqSigs" and "addresses" entirely,
always.
