3126454dcf index: prevent race by calling 'CustomInit' prior setting 'synced' flag (furszy)
Pull request description:
Decoupled from #27607.
Fixed a potential race condition in master (not possible so far) that could become an actual issue soon.
Where the index's `CustomAppend` method could be called (from `BlockConnected`) before its
`CustomInit` method, causing the index to try to update itself before it is initialized.
This could happen because we set the index `m_synced` flag (which enables `BlockConnected` events)
before calling to the child class init function (`CustomInit`). So, for example, the block filter index could
process a block before initialize the next filter position field and end up overwriting the first stored filter.
This race was introduced in bef4e405f3 from https://github.com/bitcoin/bitcoin/pull/25494.

As the fuzzer test requires all blocks to be
scanned by the wallet (because it is asserting
the wallet balance at the end), we need to
ensure that no blocks are skipped by the recently
added wallet birth time functionality.
This just means setting the chain accumulated time
to the maximum value, so the wallet birth time is
always below it, and the block is always processed.

Pull request description:
Continuation of #26078.
To improve readability instead of returning a bool and passing stuff by reference, this PR changes:
- `LookupHost` to return `std::vector<CNetAddr>`
- `LookupHost` to return `std::optional<CNetAddr>`
- `Lookup` to return `std::vector<CService>`
- `Lookup` to return `std::optional<CService>`.
- `LookupIntern` to return `std::vector<CNetAddr>`
As discussed in #26078, it would be better to avoid using `optional` in some cases, but for specific `Lookup` and `LookupHost` functions it's necessary to use `optional` to verify if they were able to catch some data from their overloaded function.

The background of this commit is an ongoing effort to decouple the
libbitcoinkernel library from code that is not strictly required by it.
The settings code belongs into the common library and namespace, since
the kernel library should not depend on it. See doc/design/libraries.md
for more information on this rationale.
Changing the namespace of the moved functions is scripted in the
following commit.

Pull request description:
I have a few PRs and branches that use these two commits, probably makes sense to split them into a separate PR to be merged sooner.
The first commit contains some things that end up being commonly used in new wallet benchmarks. These are moved into `wallet_common.{h/cpp}`.
The second commit contains a bugfix for the wallet_balance benchmark where it calls `LoadWallet` in the wrong place. It's unnecessary to call that function in this benchmark. Although this does not cause any issues currently, it ends up causing issues in some PRs and branches that I'm working on.

Remove access to the global gArgs for getting the directory in
utxo_snapshot.
This is done in the context of the libbitcoinkernel project, wherein
reliance of libbitcoinkernel code on the global gArgs is incrementally
removed.
Remove access to the global gArgs for the stopatheight argument and
replace it by adding a field to the existing ChainstateManager Options
struct.
This should eventually allow users of the ChainstateManager to not rely
on the global gArgs and instead pass in their own options.

This pull request is part of the `libbitcoinkernel` project https://github.com/bitcoin/bitcoin/issues/27587https://github.com/bitcoin/bitcoin/projects/18 and more specifically its "Step 2: Decouple most non-consensus code from libbitcoinkernel".
---
It removes the kernel library's dependency on `util/system` and `interface_ui`. `util/system` contains networking and shell-related code that should not be part of the kernel library. The following pull requests prepared `util/system` for this final step: https://github.com/bitcoin/bitcoin/pull/27419https://github.com/bitcoin/bitcoin/pull/27254https://github.com/bitcoin/bitcoin/pull/27238.
`interface_ui` defines functions for a more general node interface and has a dependency on `boost/signals2`. After applying the patches from this pull request, the kernel's reliance on boost is down to `boost::multiindex`.
The approach implemented here introduces some indirection, which makes the code a bit harder to read. Any suggestions for improving or reworking this pull request to make it more concise, or even reworking it into a more proper interface, are appreciated.

bc862fad29 ConnectTip: don't log total disk read time in bench (Sjors Provoost)
Pull request description:
The " Load block from disk" log introduced in #24216 incorrectly assumed `num_blocks_total` would be greater than 0. This is not guaranteed until the `ConnectBlock` call right below it.
The total and average metric is not very useful because it does not distinguish between blocks read from disk and those loaded from memory. So rather than fixing the divide by zero issue, we just drop the metric.

1111c9ac97 fuzz: Change LIMIT_TO_MESSAGE_TYPE from a compile-time to a run-time setting (MarcoFalke)
Pull request description:
The `process_message_${msg_type}` fuzz targets have many issues:
* In a context where each fuzz target must be a separate binary, this bloats the storage requirements by the number of message types.
* The qa-assets repo for fuzz inputs also bloats, because each input in the type specific folder (`./process_message_${msg_type}`) is accompanied by a similar input in the general folder (`./process_message`) or a in another specific folder. The size seems to be ~3GB for the sum of all folders vs 0.3GB for the general folder.
* Handling of different folders for each message type and one general folder for all message types (and unknown message types) is undocumented and unclear. Cross-pollination is encouraged, I guess, but who does it?
* It is unclear if the fuzz target has any value at all, given that any bug that is found here should also be found by the `process_messages` fuzz target, and historically always has been? So maybe it can even be removed completely in the future?
* (minor nit): When adding a new message type, the message type has to be added to this fuzz target as well.
Fix all issues by turning the compile-time setting into a run-time setting, thus removing the extra executables and fuzz folders. The same approach is also taken by the `rpc` fuzz target.
If someone wants to limit their fuzzing to a specific message type, they can still do it. For example,

82bb7831fa wallet: skip block scan if block was created before wallet birthday (furszy)
a082434d12 refactor: single method to append new spkm to the wallet (furszy)
Pull request description:
During initial block download, the node's wallet(s) scans every arriving block looking for data that it owns.
This process can be resource-intensive, as it involves sequentially scanning all transactions within each
arriving block.
To avoid wasting processing power, we can skip blocks that occurred before the wallet's creation time,
since these blocks are guaranteed not to contain any relevant wallet data.
This has direct implications (an speed improvement) on the underlying blockchain synchronization process
as well. The reason is that the validation interface queue is limited to 10 tasks per time. This means that no
more than 10 blocks can be waiting for the wallet(s) to be processed while we are synchronizing the chain
(activating the best chain to be more precise).
Which can be a bottleneck if blocks arrive and are processed faster from the network than what they are
processed by the wallet(s).
So, by skipping not relevant blocks in the wallet's IBD scanning process, we will also improve the chain
synchronization time.

fb02a3cd1a p2p: Log addresses of stalling peers (Martin Zumsande)
Pull request description:
This was suggested in #27705 by ArmchairCryptologist.
It allows node operators that have the `-logips` option enabled to better identify potentially misbehaving peers and maybe ban them.
This is especially helpful in case of inbound peers for which (dis)connections aren't logged per default, so it's impossible to use the debug log to connect their `nodeId` to an address unless the very noisy `net` debugging is enabled.
In case of outbound peers for which the address is potentially logged when establishing the connection, this just adds some convenience.

Pull request description:
Show an error on startup if a bitcoin datadir that is being used contains a `bitcoin.conf` file that is ignored. There are two cases where this could happen:
- One case reported in [#27246 (comment)](https://github.com/bitcoin/bitcoin/issues/27246#issuecomment-1470006043) happens when a `bitcoin.conf` file in the default datadir (e.g. `$HOME/.bitcoin/bitcoin.conf`) has a `datadir=/path` line that sets different datadir containing a second `bitcoin.conf` file. Currently the second `bitcoin.conf` file is ignored with no warning.
- Another way this could happen is if a `-conf=` command line argument points to a configuration file with a `datadir=/path` line and that path contains a `bitcoin.conf` file, which is currently ignored.
This change only adds an error message and doesn't change anything about way settings are applied. It also doesn't trigger errors if there are redundant `-datadir` or `-conf` settings pointing at the same configuration file, only if they are pointing at different files and one file is being ignored.

The WalletBalance benchmarks would incorrectly call LoadWallet after the
wallet has been setup. LoadWallet expects to be the first thing that is
called and for the CWallet to be in a fresh state. When it is not, it
results in bogus pointers which can cause segfaults during this
benchmark.
The wallet tests and benchmarks both had helper functions for loading
and unloading the wallet for the test that were almost identical.
These functions are consolidated and reused.
To avoid wasting processing power, we can skip blocks that occurred
before the wallet's creation time, since these blocks are guaranteed
not to contain any relevant wallet data.
This has direct implications (an speed improvement) on the underlying
