CAddrInfo objects are an implementation detail of how AddrMan manages and adds
metadata to different records. Encapsulate this logic by updating Select &
SelectTriedCollision to return the additional info that the callers need.
Improve readability of code, simplify future scripted diff cleanup PRs, and be
more consistent with naming for GetBoolArg.
This will also be useful for replacing runtime settings type checking
with compile time checking.

The benchmarks can now run much longer due to the minimum of 10ms or
directly with -min_time. With -min_time=20000 I could trigger two ubsan
errors in the benchmarks, which are fixed in this commit by using
unsigned type and adding "& 0xFF".
- use ALLOW_BOOL for -list arg instead of ALLOW_ANY
- touch up `-asymptote=<n1,n2,n3...>` help
- pack Args struct a bit more efficiently
- handle args in alphabetical order
When it is not easily possible to stabilize benchmark machine and code
the argument -min_time can be used to specify a minimum duration
that a benchmark should take. E.g. choose -min_time=1000 if you
are willing to wait about 1 second for each benchmark result.
The default is now set to 10ms instead of 0, which should make runs on
fast machines more stable with negligible slowdown.
Moves copying of the setup into the benchmark loop so it is possible
to run the loop for an arbitrary number of times.
The overhead due to copying the candidates inside the loop is about 3%.
Moves some of the setup into the benchmark loop so it is possible to run
the loop for an arbitrary number of times. Due to recent optimizations
in #22974 the benchmark now runs much faster, so the inner loop now calls
Good() 32 times as often to get better numbers.
Renamed the benchmark to AddrManAddThenGood because that's now what is
actually tested. To get the the number of just Good(), one needs to
subtract the benchmark result of AddrManAdd.
Introduced in #19055, MuHashDiv benchmark used to multiply with a loop
based on epochIterations. That does not do what it is supposed to do,
because epochIterations() is determined automatically from nanobench.
Also, multiplication is not needed for the algorithm (as pointed out by
a comment in #19055), so it's better to remove this loop.
Most importantly, this update fixes a bug in nanobench that always
disabled performance counters on linux.
It also adds another sanitizer suppression that is caught in clang++ 12.

Pull request description:
Commit 181a1207 introduced an initialization order bug: CAddrMan's m_asmap must be set before deserializing peers.dat.
The first commit restores the correct initialization order. The remaining commits make `CAddrMan::m_asmap` usage safer:
- don't reach into `CAddrMan`'s internal data from `CConnMan`
- set `m_asmap` in the initializer list and make it const
- make `m_asmap` private, and access it (as a reference to const) from a getter.
This ensures that peers.dat deserialization must happen after setting m_asmap, since m_asmap is set during CAddrMan construction.

Followup to commit "MOVEONLY: CWallet transaction code out of
wallet.cpp/.h" that detaches and renames some CWalletTx methods, making
into them into standalone functions or CWallet methods instead.
There are no changes in behavior and no code changes that aren't purely
mechanical. It just gives spend and receive functions more consistent
names and removes the circular dependencies added by the earlier
MOVEONLY commit.
There are also no comment or documentation changes. Removed comments
from transaction.h are just migrated to spend.h, receive.h, and
wallet.h.
Just use unique_ptr<CAddrMan>s and reset the pointer if a frest addrman is required.
Also make CAddrMan::Clear() private to ensure that no call sites are missed.
Currently addrman consistency checks are a compile time option, and are not
enabled in our CI. It's unlikely anyone is running these consistency checks.
Make them a runtime option instead, where users can enable addrman
consistency checks every n operations (similar to mempool tests). Update
the addrman unit tests to do internal consistency checks every 100
operations (checking on every operations causes the test runtime to
increase by several seconds).
Also assert on a failed addrman consistency check to terminate program
execution.
fa621ededd refactor: Pass script verify flags as uint32_t (MarcoFalke)
Pull request description:
The flags are cast to unsigned in the interpreter anyway, so avoid the confusion (and fuzz crashes) by just passing them as unsigned from the beginning.
Also, the flags are often inverted bit-wise with the `~` operator, which also works on signed integers, but might cause confusion as the sign bit is flipped.

Overall PR: #20158 (tree-wide: De-globalize ChainstateManager)
The first 2 commits are fixups addressing review for the last bundle: #21391
NEW note:
1. I have opened #21766 which keeps track of potential improvements where the flaws already existed before the de-globalization work, please post on that issue about these improvements, thanks!
Note to reviewers:
1. This bundle may _apparently_ introduce usage of `g_chainman` or `::Chain(state|)Active()` globals, but these are resolved later on in the overall PR. [Commits of overall PR](https://github.com/bitcoin/bitcoin/pull/20158/commits)
2. There may be seemingly obvious local references to `ChainstateManager` or other validation objects which are not being used in callers of the current function in question, this is done intentionally to **_keep each commit centered around one function/method_** to ease review and to make the overall change systematic. We don't assume anything about our callers. Rest assured that once we are considering that particular caller in later commits, we will use the obvious local references. [Commits of overall PR](https://github.com/bitcoin/bitcoin/pull/20158/commits)
3. When changing a function/method that has many callers (e.g. `LookupBlockIndex` with 55 callers), it is sometimes easier (and less error-prone) to use a scripted-diff. When doing so, there will be 3 commits in sequence so that every commit compiles like so:
1. Add `new_function`, make `old_function` a wrapper of `new_function`, divert all calls to `old_function` to `new_function` **in the local module only**
2. Scripted-diff to divert all calls to `old_function` to `new_function` **in the rest of the codebase**
3. Remove `old_function`

Pull request description:
Changes `KnapsackSolver` to use effective values instead of just the nominal txout value. Since fees are taken into account during the selection itself, we finally get rid of the `CreateTransaction` loop as well as a few other things that only were only necessary because of that loop.
This should not change coin selection behavior at all (except maybe remove weird edge cases that were caused by the loop). In order to keep behavior the same, `KnapsackSolver` will select outputs with a negative effective value (as it did before).

The fees for transaction overhead and recipient outputs are now included
in nTargetValue instead of being a separate parameter. For the coin
selection algorithms, it doesn't matter that these are separate as in
either case, the algorithm needs to select enough to cover these fees.
Note that setting nValueToSelect is changed as it now includes
not_input_fees. Without the change to how nValueToSelect is increased
for KnapsackSolver, this would result in overpaying fees. The change to
increase by the difference between nFeeRet and not_input_fees allows
this to have the same behavior as previously.
Additionally, because we assume that KnapsackSolver will always find a
solution that requires change (we assume that BnB always finds a
non-change solution), we also include the fee for the change output in
KnapsackSolver's target. As part of this, we also use the changeless
nFeeRet when iterating for KnapsackSolver. This is because we include
the change fee when doing KnapsackSolver, so nFeeRet on further
iterations won't include the change fee.

3820090bd6 Make all SignatureChecker explicit about missing data (Pieter Wuille)
b77b0cc507 Add MissingDataBehavior and make TransactionSignatureChecker handle it (Pieter Wuille)
Pull request description:
Currently we have 2 levels of potentially-missing data in the transaction signature hashes:
* P2WPKH/P2WSH hashes need the spent amount
* P2TR hashes need all spent outputs (amount + scriptPubKey)
Missing amounts are treated as -1 (thus leading to unexpected signature failures), while missing outputs in P2TR validation cause assertion failure. This is hard to extend for signing support, and also quite ugly in general.
In this PR, an explicit configuration option to {Mutable,}TransactionSignatureChecker is added (MissingDataBehavior enum class) to either select ASSERT_FAIL or FAIL. Validation code passes ASSERT_FAIL (as at validation time all data should always be passed, and anything else is a serious bug in the code), while signing code uses FAIL.
The existence of the ASSERT_FAIL option is really just an abundance of caution. Always using FAIL should be just fine, but if there were for some reason a code path in consensus code was introduced that misses certain data, I think we prefer as assertion failure over silently introducing a consensus change.
Potentially useful follow-ups (not for this PR, in my preference):
* Having an explicit script validation error code for missing data.
* Having a MissingDataBehavior::SUCCEED option as well, for use in script/sign.cpp DataFromTransaction (if a signature is present in a witness, and we don't have enough data to fully validate it, we should probably treat it as valid and not touch it).

1a6a0b0dfb wallet: Use existing feerate instead of getting a new one (Andrew Chow)
Pull request description:
During coin selection, there are various places where we need to have a feerate. We need the feerate for the transaction itself, the discard fee rate, and long term feerate. Fetching these each time we need them can lead to a race condition where two feerates that should be the same are actually different. One particular instance where this can happen is during the loop in `CreateTransactionInternal`. After inputs are chosen, the expected transaction fee is calculated using a newly fetched feerate. If `pick_new_inputs == false`, the loop will go again with the assumption that the fee for the transaction remains the same. However because the feerate is fetched again, it is possible that it actually isn't and this causes coin selection to fail.
Instead of fetching the feerate each time it is needed, we fetch them all at once at the top of `CreateTransactionInternal`, store them in `CoinSelectionParams`, and use them where needed.
While some of these fee rates probably don't need this caching, I've done it for consistency and the guarantee that they remain the same.
