7e22d80af3 addrman: fix incorrect named args (fanquake)
67f654ef61 doc: Document clang-tidy in dev notes (MarcoFalke)
Pull request description:
The documentation, and a single commit extracted from #24661.
Motivation:
> Incorrect named args are source of bugs, like https://github.com/bitcoin/bitcoin/pull/22979.
> To allow them being checked by clang-tidy, use a format it can understand.

Pull request description:
Closes#24458 - the wallet always chooses 1 million sats as its change target, making it easier to fingerprint transactions created by the Core wallet. Instead of using a fixed value, choose one randomly each time (within a range). Using 50ksat (around $20) as the lower bound and `min(1 million sat, 2 * average payment value)` as the upper bound.
RFC: If the payment is <25ksat, this doesn't work, so we're using the range (payment amount, 50ksat) instead.

da2bc865d6 [wallet] don't create long chains by default (glozow)
Pull request description:
Default mempool policy doesn't let you have chains longer than 25 transactions. This is locally configurable of course, but it's not really safe to assume that a chain longer than 25 transactions will propagate. Thus, the wallet should probably avoid creating such transactions by default; set `DEFAULT_WALLET_REJECT_LONG_CHAINS` to true.

cccc1e70b8 Enforce Taproot script flags whenever WITNESS is set (MarcoFalke)
fa42299411 Remove nullptr check in GetBlockScriptFlags (MarcoFalke)
faadc606c7 refactor: Pass const reference instead of pointer to GetBlockScriptFlags (MarcoFalke)
Pull request description:
Now that Taproot is active, it makes sense to enforce its rules on all blocks, even historic ones, regardless of the deployment status.
### Benefits:
(With "script flags" I mean "taproot script verification flags".)
* Script flags are known ahead for all blocks (even blocks not yet created) and do not change. This may benefit static analysis, code review, and development of new script features that build on Taproot.
* Any future bugs introduced in the deployment code won't have any effect on the script flags, as they are independent of deployment.
* Enforcing the taproot rules regardless of the deployment status makes testing easier because invalid blocks after activation are also invalid before activation. So there is no need to differentiate the two cases.
* It gives belt-and-suspenders protection against a practically expensive and theoretically impossible IBD reorg attack where the node is eclipsed. While `nMinimumChainWork` already protects against this, the cost for a few months worth of POW might be lowered until a major version release of Bitcoin Core reaches EOL. The needed work for the attack is the difference between `nMinimumChainWork` and the work at block 709632.
For reference, previously the same was done for P2SH and WITNESS in commit 0a8b7b4b33.
### Implementation:
I found one block which fails verification with the flags applied, so I added a `TaprootException`, similar to the `BIP16Exception`.
For reference, the debug log:
```
ERROR: ConnectBlock(): CheckInputScripts on b10c007c60e14f9d087e0291d4d0c7869697c6681d979c6639dbd960792b4d41 failed with non-mandatory-script-verify-flag (Witness program was passed an empty witness)

```
Hint for testing, make sure to set `-noassumevalid`.
### Considerations
Obviously this change can lead to consensus splits on the network in light of massive reorgs. Currently the last block before Taproot activation, that is the last block without the Taproot script flags set, is only buried by a few days of POW. However, when and if this patch is included in the next major release, it will be buried by a few months of POW. BIP90 considerations apply when looking at reorgs this large.

Instead of using the location of the makefile [automatic variable](https://www.gnu.org/software/make/manual/make.html#Automatic-Variables) `$<` I extract just the basename and then prepend a new location `./test`. This is done because `$<` represents the variable name AND location of the prerequisite here.

Pull request description:
While working on coin selection code, it occurred to me that `CInputCoin` is really a subset of `COutput` and the conversion of a `COutput` to a `CInputCoin` does not appear to be all that useful. So this PR adds fields that are present in `CInputCoin` to `COutput` and replaces the usage of `CInputCoin` with `COutput`.
`COutput` is also moved to coinselection.h. As part of this move, the usage of `CWalletTx` is removed from `COutput`. It is instead replaced by storing a `COutPoint` and the `CTxOut` rather than the entire `CWalletTx` as coin selection does not really need the full `CWalletTx`. The `CWalletTx` was only used for figuring out whether the transaction containing the output was from the current wallet, and for the transaction's time. These are now parameters to `COutput`'s constructor.

b2813980b8 init: disallow reindex-chainstate when pruning (Martin Zumsande)
Pull request description:
The combination of `-reindex-chainstate` and `-prune` currently makes the node stuck in an endless loop:
- `LoadChainstate()` will wipe the existing chainstate (so we have no genesis block anymore). It won't clean up unusable block files by calling `CleanupBlockRevFiles()` as for full `-reindex`.
- `ThreadImport()` has [logic](91d12344b1/src/node/blockstorage.cpp (L855)) of reloading Genesis after reindexing. This is what makes full `-reindex` work with `-prune` but it's not executed for `-reindex-chainstate`.
- Since we still don't have a genesis block, init will wait for it forever in an endless loop ([code](91d12344b1/src/init.cpp (L1630-L1640))).
Fix this by disallowing `-reindex-chainstate` together with `-prune`. This is discouraged in the help for `-reindex-chainstate` anyway ("When in pruning mode or if blocks on disk might be corrupted, use full -reindex instead.") but wasn't enforced.

39b1763730 Replace use of `ArgsManager` with `DatabaseOptions` (Kiminuo)
Pull request description:
Contributes to #21005.
The goal of this PR is to remove `gArgs` from database classes (i.e. `bdb.h` and `sqlite.h`) so that they can be tested without relying on `gArgs` in tests.
Notes:
* My goal is to enable unit-testing without relying on `gArgs` as much as possible. Global variables are hard to reason about which in turn makes it slightly harder to contribute to this codebase. When the compiler does the heavy lifting for us and allows us only to construct an object (or call a method) with valid parameters, we may also save some time in code reviews. The cost for this is passing an argument which is not for free but the cost is very miniscule compared to benefits, I think.
* GUI code is an exception because it seems fine to have `gArgs` there so I don't plan to make changes in `src/qt` folder, for example.
* My approach to removal of `gArgs` uses is moving from lower levels to upper ones and pass `ArgsManager` as an argument as needed. The approach is very similar to what #20158.

These operators are used only by the tests in std::mismatch. As
std::mismatch can take a binary predicate, we can use a lambda that
achieves the same instead.
