Andrew Poelstra 36e5e2a7f1 Merge 9a154599fe into merged_master (Elements PR ElementsProject/elements#900)
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.
