603d295199 test: wallet: add coverage for `-spendzeroconfchange` setting (Sebastian Falbesoner)
50112034bc test: remove `-spendzeroconfchange` setting from mempool_limit.py (Sebastian Falbesoner)
Pull request description:
This PR adds missing test coverage for the `-spendzeroconfchange` setting (in particular the non-default case `=0`). Note that in contrast to the name, the setting does not only apply to change outputs, but in fact to _all_ unconfirmed outputs that we sent to ourselves, i.e. we can trigger the testing path simply with a single recipient address. The first commit removes the setting from the functional test mempool_limit.py, where it doesn't have any effect, since the test was changed to use MiniWallet in commit dddca3899c.

fa9f6d7bcd rpc: Run type check against RPCArgs (MarcoFalke)
faf96721a6 test: Fix wrong types passed to RPCs (MarcoFalke)
Pull request description:
It seems brittle to require `RPCTypeCheck` being called inside the code logic. Without compile-time enforcement this will lead to places where it is forgotten and thus to inconsistencies and bugs. Fix this by removing the calls to `RPCTypeCheck` and doing the check internally.
The changes should be reviewed as refactoring changes. However, if they change behavior, it will be a bugfix. For example the changes here happen to also detect/fix bugs like the one fixed in commit 3b5fb6e77a.

42029a7fd4 test: remove redundant blocks generation logic (kouloumos)
0377d6bb42 test: add `rescan_utxos` in MiniWallet's initialization (kouloumos)
Pull request description:
When a pre-mined blockchain is used (default behavior), it [contains coinbase outputs in blocks 76-10](07c54de550/test/functional/test_framework/test_framework.py (L809-L813)) to [the MiniWallet's default address](07c54de550/test/functional/test_framework/wallet.py (L99-L101)). That's why we always* `rescan_utxos()` after initializing the MiniWallet, in order for the MiniWallet to account for those mature UTXOs.
> The tests following this usage pattern can be seen with:
> ```git grep -n "MiniWallet(" $(git grep -le "rescan_utxos()" $(git grep -Le "self.setup_clean_chain = True"))```
**This PR adds `rescan_utxos()` inside MiniWallet's initialization to simplify usage when the MiniWallet is used with a pre-mined chain.**
### secondary changes
- *There are a few tests that use the pre-mined blockchain but do not `rescan_utxos()`, they instead generate new blocks to create mature UTXOs.
> Those were written before the `rescan_utxos()` method was introduced with https://github.com/bitcoin/bitcoin/pull/22955 (fac66d0a39) and can be seen with:
> `git grep -n "MiniWallet(" $(git grep -Le "rescan_utxos()" $(git grep -Le "self.setup_clean_chain = True"))`
>
After including `rescan_utxos()` inside MiniWallets initilization, this blocks generation logic is not needed as the MiniWallet already accounts for enough mature UTXOs to perform the tests. **Therefore the now redundant blocks generation logic is removed from those tests with the second commit.**
- The rest of the MiniWallet tests use a clean chain (`self.setup_clean_chain = True`) and can be seen with
`git grep -n "MiniWallet(" $(git grep -le "self.setup_clean_chain = True")`
From those, there are a few that start from a clean chain and then create enough mature UTXOs for the MiniWallet with this kind of logic:
07c54de550/test/functional/mempool_expiry.py (L36-L40)
**Those tests are simplified in the third commit to instead utilize the mature UTXOs of the pre-mined chain.**

5ca7a7be76 rpc: Return accurate results for scanblocks (Aurèle Oulès)
Pull request description:
Implements #26322.
Adds a `filter_false_positives` mode to `scanblocks` to accurately verify results from blockfilters.
If the option is enabled, pre-results given by blockfilters will be filtered out again by checking vouts and vins of all transactions of the relevant blocks against the given descriptors.

d6fc1d6a33 test: add coverage for dust mempool policy (`-dustrelayfee` setting) (Sebastian Falbesoner)
8a5dbe2879 test: add `CScript` method for checking for witness program (Sebastian Falbesoner)
Pull request description:
This PR adds missing test coverage for the `-dustrelayfee` setting, which specifies the fee-rate used to define dust. Output scripts for all common types that are treated as standard by default (P2PK, P2(W)PKH, P2(W)SH, P2TR, bare multisig, null data, unknown witness versions v2+) are created and then checked for dust-mempool-policy each via the `testmempoolaccept` RPC: a tx with an output's nValue equal to the dust threshold should be accepted, one with an nValue of just one 1 satoshi below that should be rejected with reason `dust`. This is repeatedly done for a fixed (but obviously somewhat arbitrary) list of different `-dustrelayfee` settings on a single node, including the default and zero (i.e. no dust limit) settings.
Note that the first commit introduces a necessary `CScript` helper method `IsWitnessProgram` (using PascalCase in Python is likely controversial; in this case the style for the already existing method `GetSigOpCount` was followed, which also refers to a method in the core `CScript` class).
Some historical information about dust, contributed by pablomartin4btc:
"The concept of dust was first introduced in https://github.com/bitcoin/bitcoin/pull/2577. This [commit](eb30d1a5b2) from https://github.com/bitcoin/bitcoin/pull/9380 introduced the -dustrelayfee option. Previous to that PR, the dust feerate was whatever -minrelaytxfee was set to."

This PR simplies the functional test p2p_permissions.py by using MiniWallet in order to avoid manual low-level tx creation. Also, rather than mining 100 blocks manually, the pre-mined chain of the test framework is used, which speeds up the test a little (~2-3 seconds faster on my machine).

Pull request description:
Now that libsecp256k1 has a release (https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2022-December/021271.html), update the subtree to match it.
The changes themselves are not very impactful for Bitcoin Core, but include:
* It's no longer needed to specify whether contexts are for signing or verification or both (all contexts support everything), so make use of that in this PR.
* Verification operations can use the static context now, removing the need for some infrastructure in pubkey.cpp to make sure a context exists.
* Most modules are now enabled by default, so we can drop explicit enabling for them.
* CI improvements (in particular, MSVC and more recent MacOS)
* Introduction of an internal int128 type, which has no effect for GCC/Clang builds, but enables 128-bit multiplication in MSVC, giving a ~20% speedup there (but still slower than GCC/Clang).
* Release process changes (process documentation, changelog, ...).

Pull request description:
The sync is based on `bytesrecv_per_msg["verack"]`. However, the bytes are counted before processing the message, so they are not sufficient to ensure the connection is fully up.

94d0c418c5 build: remove already tested headers from AC_CHECK_HEADERS (fanquake)
Pull request description:
These headers are already included in a default set which are checked early during configure.
We already use at least sys/types.h and unistd.h unconditionally in configure.

f9ce0eadf4 For feebump, ignore abandoned descendant spends (John Moffett)
Pull request description:
Closes#26667
To be eligible for fee-bumping, a transaction must not have any of its outputs (eg - change) spent in other unconfirmed transactions in the wallet. This behavior is currently [enforced](9e229a542f/src/wallet/feebumper.cpp (L25-L28)) and [tested](9e229a542f/test/functional/wallet_bumpfee.py (L270-L286)).
However, this check shouldn't apply to spends in abandoned descendant transactions, as explained by #26667.
`CWallet::IsSpent` already carves out an exception for abandoned transactions, so we can just use that.
I've also added a new test to cover this case.

Pull request description:
Performance of block template building matters as miners likely want to be able to start mining on a block with transactions asap after a block is found. We would want to know if a mempool PR accidentally caused, for example, a 100x slowdown. An `AssembleBlock()` bench exists, but it operates on a mempool with 101 transactions, each with 0 ancestors or descendants and with the same fee. Adding a bench with a more complex mempool is useful because (1) it's more realistic (2) updating packages can potentially cause the algorithm to take a long time.
