Pull request description:

  From Qt [docs](https://doc.qt.io/qt-5/qsettings.html#QSettings-4):

  > If [`QCoreApplication::setOrganizationName()`](https://doc.qt.io/qt-5/qcoreapplication.html#organizationName-prop) and [`QCoreApplication::setApplicationName()`](https://doc.qt.io/qt-5/qcoreapplication.html#applicationName-prop) has not been previously called, the `QSettings` object will not be able to read or write any settings, and [`status()`](https://doc.qt.io/qt-5/qsettings.html#status) will return [`AccessError`](https://doc.qt.io/qt-5/qsettings.html#Status-enum).

  Fixes bitcoin-core/gui#799.

18fb363 refactor: Extract util/fs_helpers from util/system (Ben Woosley)

Pull request description:

  This pull request is part of the `libbitcoinkernel` project bitcoin#24303 https://github.com/bitcoin/bitcoin/projects/18 and more specifically its "Step 2: Decouple most non-consensus code from libbitcoinkernel". This commit was originally authored by empact and is taken from its parent PR bitcoin#25152.

  #### Context

  There is an ongoing effort to decouple the `ArgsManager` used for command line parsing user-provided arguments from the libbitcoinkernel library (bitcoin#25290, bitcoin#25487, bitcoin#25527, bitcoin#25862, bitcoin#26177, and bitcoin#27125). The `ArgsManager` is defined in `system.h`. A similar pull request extracting functionality from `system.h` has been merged in bitcoin#27238.

  #### Changes

  Next to providing better code organization, this PR removes some reliance of the tree of libbitcoinkernel header includes on `system.h` (and thus the `ArgsManager` definition) by moving filesystem related functions out of the `system.*` files.

  There is already a pair of `fs.h` / `fs.cpp` in the top-level `src/` directory. They were not combined with the files introduced here, to keep the patch cleaner and more importantly because they are often included without the utility functions. The new files are therefore named `fs_helpers` and the existing `fs` files are moved into the util directory.

  Further commits splitting more functionality out of `system.h` are still in bitcoin#25152 and will be submitted in separate PRs once this PR has been processed.

…void resizing

a19235c Preallocate result in `TryParseHex` to avoid resizing (Lőrinc)
b7489ec Add benchmark for TryParseHex (Lőrinc)

Pull request description:

  This pull request introduces optimizations to the `TryParseHex` function, focusing primarily on the ideal case (valid hexadecimal input without spaces).
  A new benchmark, `HexParse` was introduced in a separate commit.

  The main optimization preallocates the result vector based on the input string's length. This aims to completely avoid costly dynamic reallocations when no spaces are present.

Pull request description:

  `error(...)` has many issues:

  * It is often used in the context of `return error(...)`, implying that it has a "fancy" type, creating confusion with `util::Result/Error`
  * `-logsourcelocations` does not work with it, because it will pretend the error happened inside of `logging.h`
  * The log line contains `ERROR: `, as opposed to `[error]`, like for other errors logged with `LogError`.

  Fix all issues by removing it.

ae5f720 ci: Add workaround for Homebrew's python link error (Hennadii Stepanov)

Pull request description:

  Homebrew [promoted](Homebrew/homebrew-core#150390) `python@3.12` to the default `python3`. Now, our "macOS native" CI job is facing the following issues:

  1. Installing `qt@5` [requires](https://github.com/bitcoin/bitcoin/actions/runs/8216848118/job/22471875454#step:4:51) re-installing `python@3.12`:
  ```
  ==> Fetching dependencies for qt@5: readline, python@3.12 and gettext
  ```
  2. Re-installing `python@3.12` [fails](https://github.com/bitcoin/bitcoin/actions/runs/8216848118/job/22471875454#step:4:127) due to symbolic link conflicts on macOS `x86_64`:
  ```
  ==> Pouring python@3.12--3.12.2_1.ventura.bottle.tar.gz
  Error: The `brew link` step did not complete successfully
  ```
  3. Homebrew's `python@3.12` is marked as externally managed (according to PEP 668), necessitating different approaches for installing Python packages.

  This pull request resolves all the issues mentioned above.

… add unit test

3e9c736 test: fix accurate multisig sigop count (BIP16), add unit test (Sebastian Falbesoner)

Pull request description:

  In the course of reviewing bitcoin#29589 I noticed the following buggy call-site of `CScriptOp.decode_op_n` in the CScript's `GetSigOpCount` method:
  https://github.com/bitcoin/bitcoin/blob/4cc99df44aec4d104590aee46cf18318e22a8568/test/functional/test_framework/script.py#L591-L593
  This should be `lastOpcode` rather than `opcode`. The latter is either OP_CHECKMULTISIG or OP_CHECKMULTISIGVERIFY at this point, so `decode_op_n` would result in an error. Also, in `CScript.raw_iter`, we have to return the op as `CScriptOp` type instead of a bare integer, otherwise we can't call the decode method on it. To prevent this in the future, add some simple unit tests for `GetSigOpCount`.

  Note that this was unnoticed, as the code part was never hit so far in the test framework.
