This aims to make the update process more reliable and ensures that if a plugin or theme update fails, the previous version can be safely restored.
* When updating a plugin or theme, the old version is moved to a temporary backup directory:
* `wp-content/upgrade-temp-backup/plugins/[plugin-slug]` for plugins
* `wp-content/upgrade-temp-backup/themes/[theme-slug]` for themes.
* If the update fails, then the backup kept in the temporary backup directory is restored to its original location.
* If the update succeeds, the temporary backup is deleted.
To further help troubleshoot plugin and theme updates, two new checks were added to the Site Health screen:
* A check to make sure that the `upgrade-temp-backup` directory is writable.
* A check that there is enough disk space available to safely perform updates.
To avoid confusion: The temporary backup directory will NOT be used to “roll back” a plugin to a previous version after a completed update. This directory will simply contain a transient backup of the previous version of a plugin or theme being updated, and as soon as the update process finishes, the directory will be empty.

If the `clear_working` flag in `WP_Upgrader::install_package()` is false, the source should not be removed, so `copy_dir()` should be used instead.
Partial updates, like language packs, may want to retain the destination. If the destination exists or has contents, this may be a partial update, and the destination should not be removed, so `copy_dir()` should be used instead.

The [https://make.wordpress.org/core/2021/02/19/feature-plugin-rollback-update-failure/ Rollback Update Failure feature project] has been split into two plugins for testing:
* [https://github.com/afragen/faster-updates Faster Updates] speeds up plugin or theme updates by moving files rather than copying them, thus decreasing the memory usage and reducing the chance of timeouts or running out of disk space during updates.
* [https://wordpress.org/plugins/rollback-update-failure/ Rollback Update Failure] creates a temporary backup of plugins and themes before updating. This aims to make the update process more reliable and ensure that if a plugin or theme update fails, the previous version can be safely restored.
The current priority of the feature project is to test the new `move_dir()` function, which offers better performance than `copy_dir()`. Instead of copying a directory in a recursive manner file by file from one location to another, `move_dir()` uses the `rename()` PHP function to speed up the process, which is instrumental in updating large plugins without a delay. If the renaming failed, it falls back to the `copy_dir()` WP function.
The `move_dir()` function is self-contained in the Faster Updates plugin and does not require any special hooks in core, so the conditional previously added to `WP_Upgrader::install_package()` to facilitate testing is no longer needed and can be removed.

Dynamic (non-explicitly declared) properties are deprecated as of PHP 8.2 and are expected to become a fatal error in PHP 9.0.
There are a number of ways to mitigate this:
* If it is an accidental typo for a declared property: fix the typo.
* For known properties: declare them on the class.
* For unknown properties: add the magic `__get()`, `__set()`, et al. methods to the class or let the class extend `stdClass` which has highly optimized versions of these magic methods built in.
* For unknown ''use'' of dynamic properties, the `#[AllowDynamicProperties]` attribute can be added to the class. The attribute will automatically be inherited by child classes.
Trac ticket #56034 is open to investigate and handle the third and fourth type of situations, however it has become clear this will need more time and will not be ready in time for WP 6.1.
To reduce “noise” in the meantime, both in the error logs of WP users moving onto PHP 8.2, in the test run logs of WP itself, in test runs of plugins and themes, as well as to prevent duplicate tickets from being opened for the same issue, this commit adds the `#[AllowDynamicProperties]` attribute to all “parent” classes in WP.
The logic used for this commit is as follows:
* If a class already has the attribute: no action needed.
* If a class does not `extend`: add the attribute.
* If a class does `extend`:
- If it extends `stdClass`: no action needed (as `stdClass` supports dynamic properties).
- If it extends a PHP native class: add the attribute.
- If it extends a class from one of WP's external dependencies: add the attribute.
* In all other cases: no action — the attribute should not be needed as child classes inherit from the parent.
Whether or not a class contains magic methods has not been taken into account, as a review of the currently existing magic methods has shown that those are generally not sturdy enough and often even set dynamic properties (which they should not). See the [https://www.youtube.com/watch?v=vDZWepDQQVE live stream from August 16, 2022] for more details.
This commit only affects classes in the `src` directory of WordPress core.
* Tests should not get this attribute, but should be fixed to not use dynamic properties instead. Patches for this are already being committed under ticket #56033.
* While a number bundled themes (2014, 2019, 2020, 2021) contain classes, they are not a part of this commit and may be updated separately.

While using reserved PHP keywords as parameter name labels is allowed, in the context of function calls using named parameters in PHP 8.0+, this will easily lead to confusion. To avoid that, it is recommended not to use reserved keywords as function parameter names.

[51815] introduced the creation of a temporary backup of plugins before updating.
The `move()` (and later, `move_dir()`) call) uses a `$src` parameter.
For Hello Dolly, this is `<path>/wp-contents/plugins/.` (note the period at the end).
For users on Linux and Mac, this doesn't appear to cause any problems.
However, on Windows, the move causes the plugins folder to be moved which then causes a failure when attempting to call `mkdir()`.
This commit skips any plugin whose slug is `'.'` as this slug results in the `$src` value ending in a period.

* Check for direct PHP flle access and only use `rename()` if true.
* Check whether the destination directory was successfully created.
* Clear the working directory so there is internal parity within the function between the results of a successful `rename()` and a fallback to `copy_dir()`.

This allows these actions to run ''after'' the main process, without affecting the update. Actions running on `shutdown` are immune to PHP timeouts, so in case the failure was due to a PHP timeout, we'll still be able to properly restore the previous version.

This replaces the `copy_dir()` usage in `WP_Upgrader::install_package()` and aims to avoid PHP timeout issues when installing or updating large plugins on slower systems like Vagrant or the WP Docker test environment.

Noteable changes:
- The `magic_quotes_runtime` and `magic_quotes_sybase` settings were removed in PHP 5.4, so no longer need to be set.
- Some functions that use external libraries can generate errors that can't be tested for, so are globally allowed to silence errors.
- Quite a few functions would cause errors if `safe_mode` was set. This setting was removed in PHP 5.4.
- Only a handful of `header()` calls needed corresponding `headers_sent()` checks for unit tests to pass, but more may need to be added as the nightlies builds are tested.
