16d82611812de4e91e7950fe6d31484cc7a9c937 doc: Drop no longer needed workaround for WSL (Hennadii Stepanov)
Pull request description:
This PR effectively reverts commit 4f890ba6bc8caba5394c7a5388d7f07959ced78b from https://github.com/bitcoin/bitcoin/pull/11437, which fixed some build issues on WSL seven years ago.
Testing the current master branch @ 31a3ff55154bf15fb35b157c3f67ec05408ecdf9 on Windows 11 + WSL using Ubuntu 24.04 or Debian images, I noticed that the workaround is no longer required. Moreover, it doesn't affect the build process at all, which means the hashes of the built packages in depends remain the same and the `configure` log in the main build system remains the same as well.

74a04f9e7ad6a16988149cc3438b9ce13c91cdb9 testnet: Introduce Testnet4 (Fabian Jahr)
Pull request description:
To supplement the [ongoing conceptual discussion about a testnet reset](https://groups.google.com/g/bitcoindev/c/9bL00vRj7OU/m/9yCPo3uUBwAJ) I have drafted a move to v4 including a fix to the difficulty adjustment mechanism, which was part of the motivation that started the discussion.
Conceptual considerations:
- The conceptual discussion about doing a testnet4 or softforking the fix into testnet3 is outside of the scope of this PR and I would ask reviewers to contribute their opinions on this on the ML instead. However, I am happy to adapt this PR to a softfork change on testnet3 if there is consensus for that instead.
- The difficulty adjustment fix suggested here touches the `CalculateNextWorkRequired` function and uses the same logic used in `GetNextWorkRequired` to find the last previous block that was not mined with difficulty 1 under the exceptionf. An alternative fix briefly mentioned on the mailing list by Jameson Lopp would be to "restrict the special testnet minimum difficulty rule so that it can't be triggered on the block right before a difficulty retarget". That would also fix the issue but I find my suggestion here a bit more elegant.

fa7f7ac040a9467c307b20e77dc47c87d7377ded Return XOR AutoFile from BlockManager::Open*File() (MarcoFalke)
Pull request description:
Currently the *.dat files in the blocksdir store the data received from remote peers as-is. This may be problematic when a program other than Bitcoin Core tries to interpret them by accident. For example, an anti-virus program or other program may scan them and move them into quarantine, or delete them, or corrupt them. This may cause Bitcoin Core to fail a reorg, or fail to reply to block requests (via P2P, RPC, REST, ...).
Fix this, similar to https://github.com/bitcoin/bitcoin/pull/6650, by rolling a random XOR pattern over the dat files when writing or reading them.
Obviously this can only protect against programs that accidentally and unintentionally are trying to mess with the dat files. Any program that intentionally wants to mess with the dat files can still trivially do so.
The XOR pattern is only applied when the blocksdir is freshly created, and there is an option to disable it (on creation), so that people can disable it, if needed.

Pull request description:
This is a sub-feature taken out of the original proposal for ephemeral anchors #30239
This PR makes *spending* of `OP_1 <0x4e73>` (i.e. `bc1pfeessrawgf`) standard. Creation of this output type is already standard.
Any future witness output types are considered relay-standard to create, but not to spend. This preserves upgrade hooks, such as a completely new output type for a softfork such as BIP341. It also gives us a bit of room to use a new output type for policy uses.
This particular sized witness program has no other known use-cases (https://bitcoin.stackexchange.com/a/110664/17078), s it affords insufficient cryptographic security for a secure commitment to data, such as a script or a public key. This makes this type of output "keyless", or unauthenticated.
As a witness program, the `scriptSig` of the input MUST be blank, by BIP141. This helps ensure txid-stability of the spending transaction, which may be required for smart contracting wallets. If we do not use segwit, a miner can simply insert an `OP_NOP` in the `scriptSig` without effecting the result of program execution.
An additional relay restriction is to disallow non-empty witness data, which an adversary may use to penalize the "honest" transactor when RBF'ing the transaction due to the incremental fee requirement of RBF rules.
The intended use-case for this output type is to "anchor" the transaction with a spending child to bring exogenous CPFP fees into the transaction package, encouraging the inclusion of the package in a block. The minimal size of creation and spending of this output makes it an attractive contrast to outputs like `p2sh(OP_TRUE)` and `p2wsh(OP_TRUE)` which
are significantly larger in vbyte terms.
Combined with TRUC transactions which limits the size of child transactions significantly, this is an attractive option for presigned transactions that need to be fee-bumped after the fact.

Pull request description:
It is best to store all key origin information
(master key fingerprint and all derivation steps)
in the multisig descriptor. Being explicit with
this information should be beneficial if this approach is used with other wallets/signers (whether hardware or software). There is no harm including all of this with xpubs (if anything it simplifies the test code) and makes this example/docs more complete and safer incase it is referenced by others.

fa7462c67ab9b6d45484ce92b44d03f812627d6e build: Bump clang minimum supported version to 16 (MarcoFalke)
Pull request description:
Most supported operating systems ship with clang-16 (or later), so bump the minimum to that and allow new code to drop workarounds for previous clang bugs.
For reference:
* https://packages.debian.org/bookworm/clang-16
* https://packages.ubuntu.com/noble/clang (clang-18)
* CentOS-like 8/9 Stream: All Clang versions from 16 to 17
* FreeBSD 12/13: All Clang versions from 16 to 18
* OpenSuse Tumbleweed ships with https://software.opensuse.org/package/clang (`clang18`); No idea about OpenSuse Leap
On operating systems where the clang version is not shipped by default, the user would have to use GCC, or install clang in a different way. For example:
* https://packages.debian.org/bookworm/g++ (g++-12)
* https://packages.ubuntu.com/jammy/g++ (g++-11)
* https://apt.llvm.org/, or nix, or guix, or compile clang from source, ...
**Ubuntu 22.04 LTS does not ship with clang-16**, so one of the above workarounds is needed there.
macOS 13 is unaffected, and the previous minimum requirement of Xcode15.0 remains, see also b1ba1b178f/.github/workflows/ci.yml (L93). For macOS 11 (Big Sur) and 12 (Monterey) you need to install a more recent version of llvm, this remains unchanged as well, see b1ba1b178f/doc/build-osx.md (L54).

Adds a release note for TRUC policy which will be live in v28.0.

- https://github.com/bitcoin/bitcoin/pull/29496#discussion_r1624500904
I changed error strings from "v3-violation" to "TRUC-violation" but left v3 in the debug strings because I think it might be clearer for somebody who is debugging. Similarly, I left some variables unchanged because I think they're more descriptive this way, e.g. `tx_v3_from_v2_and_v3`. I'm happy to debate places that should or shouldn't be documented differently in this PR, whatever is clearest to everyone.

This PR picks up #26088 by aureleoules which adds a bitcoind launch option `-rpccookieperms` to set the file permissions of the cookie generated by bitcoin core.
Example usage to make the generated cookie group-readable: `./src/bitcoind -rpccookieperms=group`.
Accepted values for `-rpccookieperms` are `[owner|group|all]`. We let `fs::perms` handle platform-specific permissions changes.

Code review ACK 73f0a6cbd0b628675028fbd5a37eff8115e7ccfe. Main change since last review is no longer throwing a skip exception in the rpc test on windows, so other checks can run after it, and overall test result is passing, not skipped. Also were clarifying renames and documentation improvements.
