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:
```

```
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.

Moreover, this makes net_processing C++20 compliant. Otherwise, it would
lead to a compile error (see below). C++20 disables aggregate

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.
Instead of having a pointer to the CWalletTx in COutput, we can just
store the COutPoint and the CTxOut as those are the only things we need
from the CWalletTx. Other things CWalletTx used to provide were time and
fIsFromMe but these are also being stored by COutput.

If the user has unchecked "Allow incoming connections" in
`Settings->Options...->Network` then `fListen=false` is saved in
`~/.config/Bitcoin/Bitcoin-Qt.conf`. This flips `-listen` to `false`
during startup, but leaves `-listenonion` to `true`.
This flipping of `-listen` is done in `OptionsModel::Init()` after
`InitParameterInteraction()` has been executed which would have flipped
`-listenonion`, should it have seen `-listen` being `false`
(this is a difference between `bitcoind` and `bitcoin-qt`).

b2774fc0be torcontrol: Query Tor for correct -onion configuration (Luke Dashjr)
Pull request description:
Currently, we just assume any running Tor instance provides localhost port 9050 for SOCKS, and configure `-onion` accordingly when we get a Tor control connection.
This actually queries the Tor node for its SOCKS listeners, and uses the configured port instead.
For backward compatibility, it falls back to localhost:9050 if it can't get any better port info. I'm not sure if that's the correct action to take when the Tor daemon explicitly says there are no ports listening...

4d2b503d6c gui: improve "Addresses Rate-Limited" translator comments and tooltip in peers tab (Jon Atack)
81ef1f7ef1 gui: improve "Addresses Processed" translator comments and tooltip in peers tab (Jon Atack)
77f24aac52 gui: improve "Address Relay" translator comments and tooltip in peers tab (Jon Atack)
Pull request description:
Per translator feedback in this thread: https://github.com/bitcoin-core/gui/pull/526#discussion_r809237830
*"The lack of string context in Transifex is a real problem for this project, as proper context (dev notes and/or screenshots) are essential to achieve quality translations."*
This pull adds developer notes for transifex translators via `extracomment` tags, and it improves the existing ones and their tooltips with more context, clarity and completeness for the following peer tab fields as a follow-up to bitcoin-core/gui#526:
- address relay
- addresses processed
- addressed rate-limited
It looks like only six lines of diff, but they are loooong lines.
If this is the right direction, the same can be done for other fields in follow-ups.

Instead of determining whether the containing transaction is from the
wallet dynamically as needed, just pass it in to COutput and store it.
The transaction ownership isn't going to change.
f59bee3fb2 fuzz: execute each file in dir without fuzz engine (Anthony Towns)
Pull request description:
Phony fuzzing (phuzzing)! Run the fuzz testing code against known inputs to detect errors. Advantage is you can easily test using the existing qa-assets datasets without having to compile with fuzzing enabled; disadvantage is that it doesn't do any actual fuzzing.
Example usage:
```
$ for a in ${QA_ASSETS}/fuzz_seed_corpus/*; do echo ${a##*/}; done | xargs -P8 -I {} /bin/sh -c "FUZZ={} test/fuzz/fuzz ${QA_ASSETS}/fuzz_seed_corpus/{}"
No fuzzer for address_deserialize.
No fuzzer for addrdb.
No fuzzer for banentry_deserialize.
addition_overflow: succeeded against 848 files in 0s.
asmap: succeeded against 981 files in 0s.
checkqueue: succeeded against 211 files in 0s.
...
```
(`-P8` says run 8 of the tasks in parallel)
If there are failures, the first one will be reported and the program will abort with output like:
```
fuzz: test/fuzz/versionbits.cpp:336: void (anonymous namespace)::versionbits_fuzz_target(FuzzBufferType): Assertion `exp_state != ThresholdState::FAILED' failed.
Error processing seed "corpus/versionbits/35345ae8e722234095810b1117a29b63af7621af"
```
Rebase of #22763, which was a rebase of #21496, but also reports the name of the fuzzer and the time taken.
Fixes#21461
