32e5edc0f4 wallet: avoid extra wtx lookup in AddToSpends (furszy)
Pull request description:
As `AddToSpends` is only called from `AddToWallet` and `LoadToWallet`, places where we insert the wtx into the wallet map, we can directly feed `AddToSpends` with the `wtx` and remove another extra lookup.

99b9e5f3a9 p2p: always set nTime for self-advertisements (Martin Zumsande)
Pull request description:
This logic was recently changed in 0cfc0cd322 to overwrite `addrLocal` with the address they gave us when self-advertising to an inbound peer. But if we don't also change `nTime` again from the default `TIME_INIT`, our peer will not relay our advertised address any further.

These methods haven't been used since the chainstate db cache has been
switched from per-tx to per-txout model years ago (PR #10195, commit
d342424301).
In Qt 6, registration of `QDataStream` streaming operators is done
automatically. Consequently, `qRegisterMetaTypeStreamOperators()` does
no longer exist. Calls to this method have to be removed when porting
to Qt 6.

58a9601dff build: globally define NOMINMAX (fanquake)
Pull request description:
Define (and document) `NOMINMAX` once, rather than across multiple
source files.
Defining this prevents the definition of min/max macros when using
mingw-w64, which may conflict with unprefixed std::min/max usage. While
that might not be the case for us, we'd always prefer to use the standard
library in any case.
For example:
73cadc06c6/mingw-w64-headers/include/ntdef.h (L289-L300)
Note that we already define NOMINMAX globally when building with MSVC.

25749f1df7 wallet: unify “allow/block other inputs“ concept (furszy)
Pull request description:
Seeking to make the `CoinControl` options less confusing/redundant.
It should have no functional changes.
The too long to read technical description; remove `m_add_inputs`, we can use the already existent `fAllowOtherInputs` flag.
In #16377 the `CoinControl` flag ‘m_add_inputs’ was added to tell the coin filtering and selection process two things:
- Coin Filtering: Only use the provided inputs. Skip the Rest.
- Coin Selection: Search the wtxs-outputs and append all the `CoinControl` internal and external selected outpoints to the selection result (skipping all the available output checks). Nothing else.
Meanwhile, in `CoinControl` we already have a flag ‘fAllowOtherInputs’ which is already saying:
- Coin Filtering: Only use the provided inputs. Skip the Rest.
- Coin Selection: If false, no selection process -> append all the `CoinControl` selected outpoints to the selection result (while they passed all the `AvailableCoins` checks and are available in the 'vCoins' vector).
### Changes
As can notice, the first point in the coin filtering process is duplicated in the two option flags. And the second one, is slightly different merely because it takes into account whether the coin is on the `AvailableCoins` vector or not.
So it makes sense to merge ‘m_add_inputs’ and ‘fAllowOtherInputs’ into a single field for the coin filtering process while introduce other changes to add the missing/skipped internal and external coins into 'vCoins' vector if they were manually selected by the user.
——————————————————————————————————
Just as an extra note:
On top of this, I’m working on unifying/untangling further the coin filtering and selection processes so we have less duplicate functionality in both processes.

Do the closing in `Sock::Reset()` and remove the standalone
`CloseSocket()`.
This reduces the exposure of low-level sockets (i.e. integer file
descriptors) outside of the `Sock` class.
Define (and document) `NOMINMAX` once, rather than across multiple
source files.
Defining this prevents the definition of min/max macros when using
mingw-w64, which may conflict with unprefixed std::min/max usage. While
that might not be the case for us, we'd always prefer to use the standard
library in any case.
For example:
73cadc06c6/mingw-w64-headers/include/ntdef.h (L289-L300)
Otherwise, RPC commands such as `walletcreatefundedpsbt` will not support the manual selection of locked, spent and externally added coins.
Full explanation is inside #25118 comments but brief summary is:
`vCoins` at `SelectCoins` time could not be containing the manually selected input because, even when they were selected by the user, the current `AvailableCoins` flow skips locked and spent coins.
Extra note: this is an intermediate step to unify the `fAllowOtherInputs`/`m_add_inputs` concepts. It will not be a problem anymore in the future when we finally decouple the wtx-outputs lookup process from `SelectCoins` and don't skip the user's manually selected coins in `AvailableCoins`.

4ce235ef8f wallet: return 'CoinsResult' struct in `AvailableCoins` (furszy)
Pull request description:
This started in #24845 but grew out of scope of it.
So, points tackled:
1) Avoid extra `GetWalletTx` lookups inside `AvailableCoins -> IsSpentKey`.
`IsSpentKey` was receiving the tx hash and index to internally lookup the tx inside the wallet's map. As all the `IsSpentKey` function callers already have the wtx available, them can provide the `scriptPubKey` directly.
2) Most of the time, we call `Wallet::AvailableCoins`, and later on the process, skip the non-spendable coins from the result in subsequent for-loops. So to speedup the process: introduced the ability to filter by "only_spendable" coins inside `Wallet::AvailableCoins` directly.
(the non-spendable coins skip examples are inside `AttemptSelection->GroupOutputs` and `GetAvailableBalance`).
4) Refactored `AvailableCoins` in several ways:
a) Now it will return a new struct `CoinsResult` instead of receiving the vCoins vector reference (which was being cleared at the beginning of the method anyway). --> this is coming from #24845 but cherry-picked it here too to make the following commits look nicer.
b) Unified all the 'wtx.tx->vout[I]' calls into a single call (coming from this comment https://github.com/bitcoin/bitcoin/pull/24699#discussion_r854163032).
5) The wallet `IsLockedCoin` and `IsSpent` methods now accept an `OutPoint` instead of a hash:index. Which let me cleanup a bunch of extra code.
6) Speeded up the wallet 'GetAvailableBalance': filtering `AvailableCoins` by spendable outputs only and using the 'AvailableCoins' retrieved `total_amount` instead of looping over all the retrieved coins once more.

Side topic, all this process will look even nicer with #25218

_This is a piece of #21878, chopped off to ease review._
`Sock::Wait()` waits for IO events on one socket. Introduce a similar `virtual` method `WaitMany()` that waits simultaneously for IO events on more than one socket.
Use `WaitMany()` instead of `CConnman::SocketEvents()` (and ditch the latter). Given that the former is a `virtual` method, it can be mocked by unit and fuzz tests. This will help to make bigger parts of `CConnman` testable (unit and fuzz).

Pull request description:
This is part of the `libbitcoinkernel` project: #24303, https://github.com/bitcoin/bitcoin/projects/18
This PR reduces the number of call sites where we explicitly construct CTxMemPool. This is done in preparation for later PRs which decouple the mempool module from `ArgsManager`, eventually all of libbitcoinkernel will be decoupled from `ArgsManager`.
The changes in this PR:
- Allows us to have less code churn as we modify `CTxMemPool`'s constructor in later PRs
- In many cases, we can make use of existing `CTxMemPool` instances, getting rid of extraneous constructions
- In other cases, we construct a `ChainTestingSetup` and use the `CTxMemPool` there, so that we can rely on the logic in `setup_common` to set things up correctly
## Notes for Reviewers
### A note on using existing mempools
When evaluating whether or not it's appropriate to use an existing mempool in a `*TestingSetup` struct, the key is to make sure that the mempool has the same lifetime as the `*TestingSetup` struct.
Example 1: In [`src/fuzz/tx_pool.cpp`](b4f686952a/src/test/fuzz/tx_pool.cpp), the `TestingSetup` is initialized in `initialize_tx_pool` and lives as a static global, while the `CTxMemPool` is in the `tx_pool_standard` fuzz target, meaning that each time the `tx_pool_standard` fuzz target gets run, a new `CTxMemPool` is created. If we were to use the static global `TestingSetup`'s CTxMemPool we might run into problems since its `CTxMemPool` will carry state between subsequent runs. This is why we don't modify `src/fuzz/tx_pool.cpp` in this PR.
Example 2: In [`src/bench/mempool_eviction.cpp`](b4f686952a/src/bench/mempool_eviction.cpp), we see that the `TestingSetup` is in the same scope as the constructed `CTxMemPool`, so it is safe to use its `CTxMemPool`.
### A note on checking `CTxMemPool` ctor call sites
After the "tree-wide: clang-format CTxMemPool references" commit, you can find all `CTxMemPool` ctor call sites with the following command:
```sh
git grep -E -e 'make_unique<CTxMemPool>' \
-e '\bCTxMemPool\s+[^({;]+[({]' \
-e '\bCTxMemPool\s+[^;]+;' \
-e '\bnew\s+CTxMemPool\b'
```
At the end of the PR, you will find that there are still quite a few call sites that we can seemingly get rid of:
```sh
$ git grep -E -e 'make_unique<CTxMemPool>' -e '\bCTxMemPool\s+[^({;]+[({]' -e '\bCTxMemPool\s+[^;]+;' -e '\bnew\s+CTxMemPool\b'
# rearranged for easier explication
src/init.cpp: node.mempool = std::make_unique<CTxMemPool>(node.fee_estimator.get(), mempool_check_ratio);
src/test/util/setup_common.cpp: m_node.mempool = std::make_unique<CTxMemPool>(m_node.fee_estimator.get(), 1);
src/rpc/mining.cpp: CTxMemPool empty_mempool;
src/test/util/setup_common.cpp: CTxMemPool empty_pool;
src/bench/mempool_stress.cpp: CTxMemPool pool;
src/bench/mempool_stress.cpp: CTxMemPool pool;
src/test/fuzz/rbf.cpp: CTxMemPool pool;
src/test/fuzz/tx_pool.cpp: CTxMemPool tx_pool_{/*estimator=*/nullptr, /*check_ratio=*/1};
src/test/fuzz/tx_pool.cpp: CTxMemPool tx_pool_{/*estimator=*/nullptr, /*check_ratio=*/1};
src/test/fuzz/validation_load_mempool.cpp: CTxMemPool pool{};
src/txmempool.h: /** Create a new CTxMemPool.
```
Let's break them down one by one:
```
src/init.cpp: node.mempool = std::make_unique<CTxMemPool>(node.fee_estimator.get(), mempool_check_ratio);
src/test/util/setup_common.cpp: m_node.mempool = std::make_unique<CTxMemPool>(m_node.fee_estimator.get(), 1);
```
Necessary
-----
```
src/rpc/mining.cpp: CTxMemPool empty_mempool;
src/test/util/setup_common.cpp: CTxMemPool empty_pool;
```
These are fixed in #25223 where we stop requiring the `BlockAssembler` to have a `CTxMemPool` if it's not going to consult it anyway (as is the case in these two call sites)
-----
```
src/bench/mempool_stress.cpp: CTxMemPool pool;
src/bench/mempool_stress.cpp: CTxMemPool pool;
```
Fixed in #24927.
-----
```
src/test/fuzz/rbf.cpp: CTxMemPool pool;
src/test/fuzz/tx_pool.cpp: CTxMemPool tx_pool_{/*estimator=*/nullptr, /*check_ratio=*/1};
src/test/fuzz/tx_pool.cpp: CTxMemPool tx_pool_{/*estimator=*/nullptr, /*check_ratio=*/1};
src/test/fuzz/validation_load_mempool.cpp: CTxMemPool pool{};
```
These are all cases where we don't want the `CTxMemPool` state to persist between runs, see the previous section "A note on using existing mempools"
-----
```
src/txmempool.h: /** Create a new CTxMemPool.
```
It's a comment (someone link me to a grep that understands syntax plz thx)
