fa053ab7c01c03fada91ccfce885dd32e2e830ca build: Add Centos Stream 9 EOL URL (MarcoFalke)
Pull request description:
There are no plans to switch to C++23 anytime soon in the next couple of years. The only place right now that is known to benefit is `src/compat/byteswap.h`.
However, it is still useful to test with the option, because deprecated, removed or changed language features, as well as compiler changes that are guarded by the language version will be tested and developers can learn about them upfront.
Also includes a minor doc fixup commit.

Pull request description:
This is mostly a style-cleanup for the tests' random generation:
1) `g_insecure_rand_ctx` in the tests is problematic, because the name is a leftover when the generator was indeed insecure. However, now the generator is *deterministic*, because the seed is either passed in or printed (c.f. RANDOM_CTX_SEED). Stating that deterministic randomness is insecure in the tests seems redundant at best. Fix it by just using `m_rng` for the name.
2) The global random context has many one-line aliases, such as `InsecureRand32`. This is problematic, because the same line of code may use the context directly and through a wrapper at the same time. For example in net_tests (see below). This inconsistency is harmless, but confusing. Fix it by just removing the one-line aliases.
```
src/test/net_tests.cpp: auto msg_data_1 = g_insecure_rand_ctx.randbytes<uint8_t>(InsecureRandRange(100000));
````
3) The wrapper for randmoney has the same problem that the same unit test uses the context directly and through a wrapper at the same time. Also, it has a single type of Rng hardcoded. Fix it by accepting any type.

Pull request description:
It is convenient to have a descriptor which specifies both receiving and change addresses in a single string. However, as discussed in https://github.com/bitcoin/bitcoin/issues/17190#issuecomment-895515768, it is not feasible to use a generic multipath specification like BIP 88 due to combinatorial blow up and that it would result in unexpected descriptors.
To resolve that problem, this PR proposes a targeted solution which allows only a single pair of 2 derivation indexes to be inserted in the place of a single derivation index. So instead of two descriptor `wpkh(xpub.../0/0/*)` and `wpkh(xpub.../0/1/*)` to represent receive and change addresses, this could be written as `wpkh(xpub.../0/<0;1>/*)`. The multipath specifier is of the form `<NUM;NUM>`. Each `NUM` can have its own hardened specifier, e.g. `<0;1h>` is valid. The multipath specifier can also only appear in one path index in the derivation path.
This results in the parser returning two descriptors. The first descriptor uses the first `NUM` in all pairs present, and the second uses the second `NUM`. In our implementation, if a multipath descriptor is not provided, a pair is still returned, but the second element is just `nullptr`.
The wallet will not output the multipath descriptors (yet). Furthermore, when a multipath descriptor is imported, it is expanded to the two descriptors and each imported on its own, with the second descriptor being implicitly for internal (change) addresses. There is no change to how the wallet stores or outputs descriptors (yet).
Note that the path specifier is different from what was proposed. It uses angle brackets and the semicolon because these are unused characters available in the character set and I wanted to avoid conflicts with characters already in use in descriptors.
Closes#17190

Pull request description:
This PR introduces a new CMake-based build system, which is a drop-in replacement for the current Autotools-based build system.
ML announcement: https://groups.google.com/g/bitcoindev/c/hgKkfQWzrTo
As discussed during the recent CoreDev meetup in April, the switch from Autotools to CMake is intended to happen as soon as possible after branching 28.x off, which means that 29.0 will be built using CMake.
This PR branch is essentially the [staging branch](https://github.com/hebasto/bitcoin/tree/cmake-staging), with every change reviewed and tested by a group of contributors, including (in alphabetical order):
- [**achow101**](https://github.com/achow101)

Reviewing in a separate staging repo was suggested in https://github.com/bitcoin/bitcoin/pull/27060#issuecomment-1431798320.
The accompanying changes to the OSS-Fuzz project are available in https://github.com/hebasto/oss-fuzz/pull/8.
Please refer to the [build options parity table](https://gist.github.com/hebasto/2ef97d3a726bfce08ded9df07f7dab5e). The "auto" value is no longer available; non-default values must be specified explicitly. Additionally, the new default values have been chosen to suit the everyday build experience for the majority of developers.
System requirements for using the CMake-based build system:
- CMake >= 3.22 (if not available in your system's repository, it can be downloaded from https://cmake.org/download/)
- a build tool of your choice:
- any Make (GNU Make is no longer a requirement); GNU Make is still required to build depends
- Ninja (https://ninja-build.org/)
- MSBuild
- Xcode
A note for Windows users: The default installation of the latest version of MSVC 17.10.4 includes both CMake 3.28.3 and the vcpkg package manager).
---
We, the build system developers, kindly ask reviewers to refrain from making suggestions that are not directly related to the migration process or can be implemented separately. Bugs in the scripts and errors in the updated documentation should be the focus of this PR. Please be advised that comments not aligned with this PR's goal may be ignored.
Thank you all for your understanding.

fadf0a7e15d66ba3230153e789b785e6cf8ab84c refactor: Remove Span operator==, Use std::ranges::equal (MarcoFalke)
Pull request description:
`std::span` removed the comparison operators, so it makes sense to remove them for the `Span` "backport" as well. Using `std::ranges::equal` also has the benefit that some `Span` temporary constructions can now be dropped.
This is required to move from `Span` toward `std::span`.

Follow-up to Testnet4 introduction #29775 which overlapped with work on `uint256` `consteval` ctor #30560 (the latter includes the scripted-diff commit).
Going forward `uint256{}` should be used for constants instead of `uint256S()`.

Pull request description:
Since fad2991ba073de0bd1f12e42bf0fbaca4a265508, `uint256S` has been [deprecated](fad2991ba0 (diff-800776e2dda39116e889839f69409571a5d397de048a141da7e4003bc099e3e2R138)) because it is less robust than the `base_blob::FromHex()` introduced in [the same PR](https://github.com/bitcoin/bitcoin/pull/30482). Specifically, it tries to recover from length-mismatches, recover from untrimmed whitespace, 0x-prefix and garbage at the end, instead of simply requiring exactly 64 hex-only characters. _(see also #30532)_
This PR carves out the few `uint256S` callsites that may potentially prove a bit more controversial to change because they deal with user input and backwards incompatible behaviour change.
The main behaviour change introduced in this PR is:
- `-minimumchainwork` will raise an error when input is longer than 64 hex digits
- `-assumevalid` will raise an error when input contains invalid hex characters, or when it is longer than 64 hex digits
- test: the optional RANDOM_CTX_SEED env var will now cause tests to abort when it contains invalid hex characters, or when it is longer than 64 hex digits
After this PR, the remaining work to remove `uint256S` completely is almost entirely mechanical and/or test related. I will open that PR once #30560 is merged because it builds on that.

fab0e834b8cf906c286ebbeed86eca8d65854f75 bench: [refactor] iwyu (MarcoFalke)
Pull request description:
Missing includes are problematic, because:
* Upcoming releases of a C++ standard library implementation often minimize their internal header dependencies. For example, `_LIBCPP_REMOVE_TRANSITIVE_INCLUDES` (https://libcxx.llvm.org/DesignDocs/HeaderRemovalPolicy.html). This can lead to compile failures, which are easy to fix for developers, but may not be for users. For example, commit 138f8671569f7ebb8c84e9d80c44cddeda9e3845 had to add missing includes to accommodate GCC 15 (and the commit had to be backported).
* A Bitcoin Core developer removing a feature from a module and wanting to drop the now unused includes may not be able to do so without touching other unrelated files, because those files rely on the transitive includes.
Moreover, missing or extraneous includes are problematic, because they may be confusing the code reader as to what the real dependencies are.
Finally, extraneous includes may slow down the build.
Fix all issues in `bench`, by applying the rule include-what-you-use (iwyu).
Follow-up pull requests will handle the other places.

Pull request description:
This builds on #30008 and adds data [exported](https://github.com/virtu/seed-exporter) by [my crawler](https://github.com/virtu/p2p-crawler) an additional source for seed nodes. Data covers all supported network types.
[edit: Added Luke's seeder as input as well.]
### Motivation
- Further decentralizes the seed node selection process (in the long term potentially enabling an _n_-source threshold for nodes to prevent a single source from entering malicious nodes)
- No longer need to manually curate seed node list for any network type: See last paragraph of OP in #30008. My crawler has been [discovering the handful of available cjdns nodes](https://21.ninja/reachable-nodes/nodes-by-net-type/) for around two months, all but one of which meet the reliability criteria.
- Alignment of uptime requirements for Onion and I2P nodes with those of clearnet nodes to 50%: If I'm reading the code correctly, seeders appear to optimize for up-to-dateness by using [lower connection timeouts](3c1a63c672/src/crawl.rs (L349)) than [Bitcoin Core](bc87ad9854/src/netbase.cpp (L40C27-L40C48)) to maximize throughput. Since my crawler does not have the same timeliness requirements, it opts for accuracy by using generous timeouts. As a result, its data contains additional eligible Onion (and other darknet nodes), as is shown in the histogram below. Around 4500 Onion nodes are discovered so far (blue); my data adds ~6400 more (orange); ~ 1500 nodes take longer than the default 20-second Bitcoin Core timeout and won't qualify as "good".
Here's the current results with 512 nodes for all networks except cjdns:

1b41d45d462d856a9d0b44ae0039bbb2cd78407c wallet: bugfix: ensure atomicity in settings updates (ismaelsadeeq)
Pull request description:
This PR fixes#30620.
As outlined in the issue, creating two wallets with `load_on_startup=true` simultaneously results in only one wallet being added to the startup file.
The current issue arises because the wallet settings update process involves:
1. Obtaining the settings value while acquiring the settings lock.
2. Modifying the settings value.
3. Overwriting the settings value while acquiring the settings lock again.
This sequence is not thread-safe. Different threads could modify the same base value simultaneously, overwriting data from other workers without realizing it.
The PR attempts to fix this by modifying the chain interface's `updateRwSetting` method to accept a function that will be called with the settings reference. This function will either update or delete the setting and return an enum indicating whether the settings need to be overwritten in this or not.
Additionally, this PR introduces two new methods to the chain interface:

fa5b58ea01fac1adb6336b8b6b5217193295c695 test: Avoid intermittent block download timeout in p2p_ibd_stalling (MarcoFalke)
Pull request description:
Fixes#30704
The goal of the test is to check the stalling timeout, not the block download timeout.
On extremely slow hardware (for example qemu virtual hardware), downloading the 1023 blocks may take longer than the block download timeout.
Fix it by pinning the time using mocktime, and only advance it when testing the stalling timeout.
