The `create_block` helper accepts a list of txs that it includes in the
created block, hence we don't have to do that manually. Also, rehashing
before solving the block is not needed and can be removed.
The function `trueDummy` in feature_nulldummy.py is currently more
complicated than it needs to be. Rather than converting the scriptSig to
a CScript and looping through it to build a new scriptSig with the
modified push, simply directly replace the push of null (OP_0) with a
push of one (OP_TRUE/OP_1).
Note that on master, actually an element with the value of 0x51 is
pushed (0x0151...) -- this was very likely not intended, as 0x51 is the
script op-code for OP_TRUE, and also the function's name suggests that
the "true" value shall be pushed.
This fixes a null pointer crash in the bitcoin-gui PSBT dialog. The
bitcoin-gui interfaces::Node object has a null NodeContext pointer, and
can't broadcast transactions directly. It needs to broadcast
transactions through the bitcoin-node process instead.
Blindly chose a cap of 10000 iterations for every loop, except for
the two in script_ops.cpp and scriptnum_ops.cpp which appeared to
(sometimes) be deserializing individual bytes; capped those to one
million to ensure that sometimes we try working with massive scripts.
There was also one fuzzer-controlled loop in timedata.cpp which was
already capped, so I left that alone.
git grep 'while (fuzz' should now run clean except for timedata.cpp
This does the following:
* Adds a rfc6979 argument to test_framework/key.py's sign_ecdsa to
select (deterministic) RFC6979-based nonce generation.
* Add a flag in feature_taproot.py's framework called "deterministic".
* Make the Schnorr signing in feature_taproot.py randomized by default,
reverting to the old deterministic (aux_rnd=0x0000...00) behavior
if the deterministic context flag is set.
* Make the ECDSA signing in feature_taproot.py use RFC6979-based nonces
when the deterministic context flag is set (keeping the old randomized
behavior otherwise).
libsecp256k1's secp256k1_schnorrsig_sign only follows BIP340 exactly
if an aux_rand32 argument is passed. When no randomness is used
(as is the case in the current codebase here), there is no impact
on security between not providing aux_rand32 at all, or providing
an empty one. Yet, for repeatability/testability it is simpler
to always use an all-zero one.

Pull request description:
This takes over #21859, which has [recently switched](https://github.com/bitcoin/bitcoin/pull/21859#issuecomment-921899200) to my integration branch. A few more build issues came up (and have been fixed) since, and after discussing with sipa it was decided I would open a PR to shepherd any final changes through.
> This adds a `src/minisketch` subtree, taken from the master branch of https://github.com/sipa/minisketch, to prepare for Erlay implementation (see #21515). It gets configured for just supporting 32-bit fields (the only ones we're interested in in the context of Erlay), and some code on top is added:
> * A very basic unit test (just to make sure compilation & running works; actual correctness checking is done through minisketch's own tests).
> * A wrapper in `minisketchwrapper.{cpp,h}` that runs a benchmark to determine which field implementation to use.
Only changes since my last update to the branch in the previous PR have been rebasing on master and fixing an issue with a header in an introduced file.

467fe5779c test: Correct MyPy typing for subtest decorator (Pavel Safronov)
Pull request description:
This is the part of the effort to make python typing correct https://github.com/bitcoin/bitcoin/issues/19389
The typing of the `subtest` decorator within `p2p_segwit.py` test file was incorrect.
Since `subtest` function is defined as a member of the class, it expects `self` as a first argument, and it is not provided. Hence the typing errors (that are currently suppressed by `type: ignore`).

Found 26 errors in 1 file (checked 1 source file)
```
However, the tests are passing, because there is no `self` argument passed when it is called as a decorator.
There is also suppressed pylint error `# noqa: N805` pointing to the same issue.
```
N805 first argument of a method should be named 'self'
```
So the solution is to move the `subtest` definition outside the class, so the `self` argument is no longer required.
After doing so, both mypy and unittests are successfully passing:
```
