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.
fafe896a0b test: Set regtest.BIP66Height = 102 to speed up tests (MarcoFalke)
Pull request description:
No need to waste time by forcing creation of more than 1000 blocks to get the benefits of being able to test BIP 66. Also, reducing the height makes it more likely that (third-party) tests are conforming to BIP 66, which is enforced on mainnet for all new blocks.

5a1bef60a0 test: refactor: remove binascii from test_framework (Zero-1729)
Pull request description:
This PR continues the work started in PR #22593, regarding using the `bytes` built-in module. In this PR specifically, instances of `binascii`'s methods `hexlify`, `unhexlify`, and `a2b_hex` have been replaced with the build-in `bytes` module's `hex` and `fromhex` methods where appropriate to make bytes <-> hex-string conversions consistent across the functional test files and test_framework.
Additionally, certain changes made are based on the following assumption:
```
bytes.hex(data) == binascii.hexlify(data).decode()
bytes.hex(data).encode() == binascii.hexlify(data)
```
Ran the functional tests to ensure behaviour is still consistent and changes didn't break existing tests.

222290f543 test: Set BIP34Height = 2 for regtest (MarcoFalke)
fac90c55be test: Create all blocks with version 4 or higher (MarcoFalke)
Pull request description:
BIP34 is active on the current tip of mainnet, so all miners must obey it. It would be nice if it also was active in fresh regtest instances from the earliest time possible.
I changed the BIP34 height to `2`, so that the block at height=1 may be used to mine a duplicate coinbase. (Needed to test mainnet behaviour)
This pull is done in two commits:
* test: Create all blocks with version 4 or higher:
Now that BIP34 is activated earlier, we need to create blocks with a higher version number. Just bump it to 4 instead of 2 to avoid having to bump it again later.
* test: Set BIP34Height = 2 for regtest:
This fixes the BIP34 implementation in the tests (to match the one of the Core codebase) and updates the tests where needed

8a2b58db9e test: fix segwit terminology (s/witness_program/witness_script/) (Sebastian Falbesoner)
Pull request description:
This PR fixes wrong uses of the term "witness program", which according to [BIP141](https://github.com/bitcoin/bips/blob/master/bip-0141.mediawiki#Witness_program) is defined as follows:
> A scriptPubKey (or redeemScript as defined in BIP16/P2SH) that consists of a 1-byte push opcode (for 0 to 16) followed by a data push between 2 and 40 bytes gets a new special meaning. The value of the first push is called the "version byte". **The following byte vector pushed is called the "witness program".**
In most cases where "witness program" is used in tests (concerns comments, variable names and in one instance even a function name) what we really want to denote is the "witness script". Thanks to [MarcoFalke for pointing this out in a review comment](https://github.com/bitcoin/bitcoin/pull/22363#discussion_r666794261)!
Some historical background: At the time when the P2P segwit tests were first introduced (commit 330b0f31ee, PR #8149), the term "witness program" was not used consistently in BIP141: https://bitcoin.stackexchange.com/questions/46451/what-is-the-precise-definition-of-witness-program
This was fixed in PR https://github.com/bitcoin/bips/pull/416 later.
So in some way, this PR can be seen as a very late follow-up to the BIP141 fix that also reflects these changes in the tests.

What a pain in the ass. This changes the `feature_cltv` functional test
to use the `MiniWallet`, an internal Pythonic wallet that produces
"signatures" consisting of several OP_NOPs in a row, so that this test
can be used when the wallet is disabled.
This means that the functions in feature_cltv which add a CLTV check and
change the locktime/sequence number no longer need to re-sign when they
change the txid, so they don't...HOWEVER, our Elements-specific
`feature_block_v4` test calls these functions with a real transaction
and depended on the re-signing behavior.
After several attempts at min-effort min-diff fixes I landed on this,
which simply sets the locktime at transaction creation and avoids having
to re-sign at all.
Also, I had to change the number of NOPs in the fake wallet code to make
a vsize assertion pass, presumably because of differences in Bitcoin/Elements
transaction serialization.
This is part of the "UTXO Set Statistics" project in Core, which aims
to make things like "checking coin supply" faster. This stuff, and
related things in coinstats.cpp, have always been broken for Elements
in the sense that we consider only explicit outputs and we ignore
assets (so everything just gets added together to get a meaningless
total). It probably wouldn't be too hard to restrict this to only
consider policyAsset, but it's out of scope for a rebase IMO.
Also, I think this situation is fine .. I don't understand the motivation
for this or why Core is merging this when they refuse to merge an address
index .. but I guess we'll see if there are users who care about this data
and who care about it being meaningful on Elements.
Also, apologies for the big diff -- there were some mechanical changes
to deal with CT amounts, but most of the changes related to the difference
in how fees are accounted for. While I'm not thrilled with this PR, its
functional test is really good! So I think what I eventually came up with
is internally consistent.

2ce7b47958 test: introduce `tx_from_hex` helper for tx deserialization (Sebastian Falbesoner)
Pull request description:
There are still many functional tests that perform conversions from a hex-string to a message object (deserialization) manually. This PR identifies all those instances and replaces them with a newly introduced helper `tx_from_hex`.
Instances were found via
* `git grep "deserialize.*BytesIO"`
and some of them manually, when it were not one-liners.
Further, the helper `ToHex` was removed and simply replaced by `.serialize().hex()`, since now both variants are in use (sometimes even within the same test) and using the helper doesn't really have an advantage in readability.
