WordPress tries to avoid an issue where slugs might match an existing slug of a page/post.
If we are in a hierarchical post type, there will be a level, and we can leave it the same.

The `_mb_substr()` function expects a string for the `$str` parameter, but does not do input validation. This function contains a `preg_match_all()` which also expects a string type for the given subject (i.e. `$str`).
Passing `null` to this parameter results in `preg_match_all(): Passing null to parameter #2 ($subject) of type string is deprecated` notice on PHP 8.1.
To maintain the same behaviour as before, a guard clause is added to bail out early when `$str` is passed as `null`. The outcome will, in that case, only ever be an empty string.
Note: this does mean that the `_mb_substr()` function now has a subtle difference in behaviour compared to the PHP native `mb_substr()` function as the latter ''will'' throw the deprecation notice.
The existing tests already cover this issue.

Splits the tests in the `tests/phpunit/tests/compat.php` file up into individual test classes for each function being tested.
Improvements to individual test cases:
* Adds `@covers` tags.
* Adds visibility modifiers to all methods.
* Adds function availability test.
* Where relevant, fixes the assertion parameter order.
* Data provider:
* Where relevant, reworks a test to use a data provider.
* Where relevant, renames data provider methods to have a more obvious link to the test it applies to.
* Makes the data provider more readable by adding keys within the data sets.
* Moves the data provider below its associated tests.
* Adds/removes data sets in data providers.
* Makes the actual test code more readable by using descriptive variables and multi-line function calls.
* Adds the `$message` parameter to all assertions when a test method contains more than one assertion.
Specifically for the `_mb_substr()` tests:
* Splits the `test_mb_substr_phpcore()` method into two test methods based on the PHP Core test files they are emulating.
* Makes the actual test code within the `test_mb_substr_phpcore_basic()` method more readable by using descriptive variables and multi-line function calls.
* Splits the data used for the second part of the `test_mb_substr_phpcore()` function, now `test_mb_substr_phpcore_input_type_handling()`, off into a separate data provider with named data sets.
* Removes duplicate data sets from the `data_mb_substr_phpcore_input_type_handling()`.
* Why? The PHP native tests test against upper/lowercase `false`, `true`, `null` and some other text string single quote/double quote variations. As things were, those differentiations had been undone when the coding standards were put in place, so in effect those weren't being tested anymore. And as this is userland code, there's no point in adding these differentiations back as they will be handled the same by PHP anyway (and that is safeguarded via the PHP native tests).
* Removes the "undefined variable" and "unset variable" test cases as, while those are relevant to the C code in which PHP is written, they are not relevant for testing userland code and will behave the same as the test passing `null`.

Basically, the whole `assertSameIgnoreEOL()` assertion was fundamentally flawed. The assertion contends that it checks that the expected and actual values are of the same type and value, but the reality was very different.
* The function uses `map_deep()` to potentially handle all sorts of inputs.
* `map_deep()` handles arrays and objects with special casing, but will call the callback on everything else without further distinction.
* The callback used passes the expected/actual value on to the `str_replace()` function to remove potential new line differences.
* And the `str_replace()` function will - with a non-array input for the `$subject` - always return a string.
* The output of these calls to `map_deep()` will therefore have "normalized" _all properties_ in objects, _all values_ in arrays and _all non-object, non-array values_ to strings.
* And a call to `assertSame()` will therefore NEVER do a proper type check as the type of all input has already, unintentionally, been "normalized" to string.
Aside from this clear flaw in the design of the assertion, PHP 8.1 now exposes a further issue as a `null` value for an object property, an array value or a plain value, will now yield a ` str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated` notice.
To fix both these issues, the fix in this PR ensures that the call to `str_replace()` will now only be made if the input is a text string.
All other values passed to the callback are left in their original type.
This ensures that a proper value AND type comparison can be done as well as prevents the PHP 8.1 deprecation notices.

This commit:
- Fixes type-casting of non-string values to `string` (the flawed part of this assertion) by invoking `str_replace()` when the value is of string type.
- Fixes the PHP 8.1 `str_replace(): Passing null to parameter #3 ($subject) of type array|string is deprecated` deprecation notice.
- Micro-optimization: skips `map_deep()` when actual and/or expected are `null` (no need to process).
- Adjusts the method documentation for both this method and the `assertEqualsIgnoreEOL()` alias method to document that the `$expected` and `$actual` parameters can be of any type.

If the `'widget_testwidget'` option does not exist, `false` was returned from `get_option()`. The `set_up()` logic expects an `array()` and assigns values to keys without checking for an array. The automatic creation of an array (autovivification) triggers a `Deprecated: Automatic conversion of false to array is deprecated in` deprecation notice on PHP 8.1.
This commit:
- Fixes the deprecation notice by making the default value an empty array.
- Moves getting the option within the conditional where it's needed.
- Provides a micro-optimization by only getting the options when the conditions are correct for processing.
- Makes the code consistent within the `set_up()` for both `get_option()` instances.

Global styles are used in a few different contexts (front, editor, customizer, the theme directory). In the last two contexts, it's important that switching themes immediately refreshes the global stylesheet, to avoid situations in which the styles of the previous theme load with the new one. This was brought up at WordPress/gutenberg#34531 (customizer) and at meta.trac.wordpress.org/ticket/5818 (theme directory).
This commit makes sure the stylesheet is regenerated upon switching themes.

In all four of the `get_option()`, `add_option()`, `update_option()` and `delete_option()` functions, the `$option` parameter (i.e. the option name) is passed to the PHP native `trim()` function without prior input validation.
In PHP 8.1, this could lead to a `trim(): Passing null to parameter #1 ($string) of type string is deprecated` for each of these functions.
`trim()`:
- expects a text string and is only useful when ''passed'' a text string as no other variable type can contain whitespace.
- will always return a `string`, which means that in practice for any non-string values passed, it would effectively function as a type cast to string.
This commit:
- Adds a check to verify the `$option` name is a scalar before processing it with `trim()`.
- The "type cast" behavior is maintained.
- If the given `$option` name is not a scalar, such as `null`, the fix prevents the PHP 8.1 deprecation notice.
- Tests are added for valid but undesired option names to safeguard against regressions.
This issue is already covered by:
- the existing `Tests_Option_Option::test_bad_option_names()` test group.
- the new `test_valid_but_undesired_option_names()` tests.

The shortcode content is expected to be a string, not `null`. `do_shortcode()` expects a string for `$content`.
The `img_caption_shortcode()` also expects a string for the `$content` parameter and is expected to return a string for the HTML content to display the caption.
Prior to this commit:
The default value for the `$content` parameter was set to `null`. If no `$content` was passed, the function:
- could return `null` when the `$atts['width'] < 1` or there was no caption
- else, it invoked `do_shortcode( $content )` passing `null` which on PHP 8.1+ triggers a deprecation notice:
{{{
strpos(): Passing null to parameter #1 ($haystack) of type string is deprecated
}}}
This commit:
- Fixes the default `$content` value to align to the expected shortcode content of `string`, not `null`.
- Fixes the PHP 8.1 deprecation notice when `null` was being passed to `do_shortcode()`.
- Changes the assertion in a couple of tests to check for the empty string instead of `null.

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 temporary backup kept in the `upgrade/temp-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 `temp-backup` directory is writable.
* A check that there is enough disk space available to safely perform updates.
To avoid confusion: The `temp-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.

Previously, two situations were taken in to account:
1. The `WP_TESTS_PHPUNIT_POLYFILLS_PATH` constant is defined => just show a message about the version mismatch.
2. The constant is not defined => show a message to run `composer update`. This message is intended for people trying to run the WP Core tests.
This could lead to an unclear situation for people trying to run plugin/theme integration tests without the new `WP_TESTS_PHPUNIT_POLYFILLS_PATH` constant being defined.
They could be shown the message to run `composer update` while if they would do so for their local install without adding the Polyfills, the message would still display the next time they would attempt to run the tests.
This commit:
1. Provides more information about the PHPUnit Polyfills version detected vs the version expected.
2. Shows a more specific message to guide users which have the `WP_TESTS_PHPUNIT_POLYFILLS_PATH` constant declared.
3. Only shows the message to run `composer update` when the `WP_RUN_CORE_TESTS` constant is declared to prevent confusing people more.

Previously, two situations were taken in to account:
1. The `WP_TESTS_PHPUNIT_POLYFILLS_PATH` constant is defined => show message specific to that constant not being set correctly.
This message would typically be shown for plugin/theme integration tests which are already aware of the changes in WP 5.9.

The `Requests_Cookie` class expects valid - non-`null` - attributes to be passed, either as an array or as a `Requests_Utility_CaseInsensitiveDictionary` object.
However, the `WP_Http_Cookie::get_attributes()` explicitly sets the `expires`, `path` and `domain` index keys in an array with values which _may_ be `null`. This will cause `strtotime(): Passing null to parameter #1 ($datetime) of type string is deprecated`-like errors when the attributes are passed to the `Requests_Cookie` class.
Note: a `null` value for `path` would generate a similar deprecation notice, but for the `preg_match()` function.
Fixed by using `array_filter()` on the attributes to explicitly filter out `null` values before passing the attributes to `Requests_Cookie`.
Note: I'm choosing to explicitly only filter `null` values. Using `array_filter()` without a callback would filter out all "empty" values, but that may also remove values which are explicitly set to `false` or `0`, which may be valid values.

The PHP native `mysqli_real_escape_string()` function expects to be passed a string as the second parameter and this is not a nullable parameter.
Passing `null` to it will result in a `mysqli_real_escape_string(): Passing null to parameter #2 ($string) of type string is deprecated` notice on PHP 8.1.
Previously, an input type check was put in place to prevent fatal errors on PHP 8.0 when an array, object or resource was passed. Changeset [48980].
A `null` value was explicitly excluded from that check, even though a `null` value being passed would only ever result in an empty string anyway.
This commit changes the previous input type check to also bow out early for `null` values and to automatically return an empty string for those.

The `wp_privacy_anonymize_ip()` function expects a string for the `$ip_addr` parameter, but did not do any input validation.
One of the pre-existing test cases, passed `null` to the function, leading to a `substr_count(): Passing null to parameter #1 ($haystack) of type string is deprecated` notice on PHP 8.1.
Fixed now by doing a cursory check on the variable at the start of the function and bowing out early for a number of cases (`null`, `false`, `0`, `''`) which would all result in the same `0.0.0.0` output anyway.
Follow-up [42971].

Adds a few more invalid IP test cases.
Adds extra `@covers` tag for the two functions which are testing the `wp_privacy_anonymize_ip()` function.
(At class level, the `wp_privacy_anonymize_data()` is set as covered).
