`file_get_contents()` is faster than `fread()`, because the PHP core can decide how to best read the remaining file; it could decide to issue just one `read()` call or `mmap()` the file first.
Per the PHP manual, `file_get_contents()` or `stream_get_contents()` is the preferred way to read the contents of a file into a string. It will use memory mapping techniques if supported by the OS to enhance performance.

Twenty Twenty-Two requires WordPress 5.9 but currently can't be (re)activated in the 5.9 branch because `version_compare( '5.9-RC3-52627', '5.9', '>=' )` as used by `is_wp_version_compatible()` returns `false`. To appreciate the testing of upcoming versions any `-alpha`, `-RC`, `-beta` suffixes are now stripped off from the WordPress version before checking for compatibility.

The code in `wp_list_filter()` was a duplicate of `wp_filter_object_list()`, minus the `WP_List_Util::pluck()` (used when `$field` is configured).
In testing the wrapper, discovered an edge case (and potential bug) in `WP_List_Util::filter()` where if the operator matches an empty array was returned without resetting the output property. Without that property being set correctly, `WP_List_Util::get_output()` was not correct. This commit also fixes this by resetting the property to an empty array.

>PHP natively allows for autovivification (auto-creation of arrays from falsey values). This feature is very useful and used in a lot of PHP projects, especially if the variable is undefined. However, there is a little oddity that allows creating an array from a `false` and `null` value.
The above quote is from the PHP 8.1 RFC and the (accepted) RFC changes the behaviour described above to deprecated auto creation of arrays from `false`. As it is deprecated, it _will_ still work for the time being, but as of PHP 9.0, this will become a Fatal Error, so we may as well fix it now.
The `recurse_dirsize()` function retrieves a transient and places it in the `$directory_cache` variable, but the `get_transient()` function in WP returns `false` when the transient doesn't exist, which subsequently can lead to the above mentioned deprecation notice.
By verifying that the `$directory_cache` variable is an array before assigning to it and initializing it to an empty array, if it's not, we prevent the deprecation notice, as well as harden the function against potentially corrupted transients where this transient would not return the expected array format, but some other variable type.
Includes adding dedicated unit tests for both the PHP 8.1 issue, as well as the hardening against corrupted transients.
Includes some girl-scouting: touching up a parameter description and some code layout.

When the PHP native `dirname()` function is used on a Windows disk name - i.e. `C:\`-, it will return the same, i.e, it will return `C:\` again.
The `clean_dirsize_cache()` function didn't have guard clause against this, which meant that on Windows based systems and IIS servers, this function would result in WordPress getting stuck into an infinite loop.
The adjustment to the `while` part of the function fix this by checking if the return value of the `dirname()` function call is the same as the original path passed to `dirname()`, which effectively fixes the infinite loop.
A number of other improvements made:
1. Add input validation for the `$path` parameter to guard against invalid variable types being passed into the function.
2. Guard against an empty `$path` parameter, which would result in an infinite loop on both Windows as well as *nix based systems.
In both these cases, a PHP notice will now be thrown.
3. When a non-empty string, which isn't a path would previously be passed, the `dirname()` function would transform that to a `.` and the `.` key in the transient cache would be cleared out.
This was a bug as there is no relation between a non-path string and the root directory of file system.
This bug has been fixed by checking that something could actually be a path and handling received non-empty, non-path input parameters in a special way, i.e only removing the cache key for the passed string and bowing out from further processing.
Unfortunately, no tests can be added to guard against the infinite loop.
For the other fixes, we have added appropriate unit tests.

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.

Switching a WordPress site from HTTP to HTTPS has historically been a tedious task. While on the surface the Site Address and WordPress Address have to be updated, existing content still remains using HTTP URLs where hard-coded in the database. Furthermore, updating _two_ URLs to migrate to HTTPS is still a fairly unintuitive step which is not clearly explained.
This changeset simplifies migration from HTTP to HTTPS and, where possible, makes it a one-click interaction.
* Automatically replace insecure versions of the Site Address (`home_url()`) with its HTTPS counterpart on the fly if the site has been migrated from HTTP to HTTPS. This is accomplished by introducing a `https_migration_required` option and enabling it when the `home_url()` is accordingly changed.
* A new `wp_replace_insecure_home_url()` function is hooked into various pieces of content to replace URLs accordingly.
* The migration only kicks in when the Site Address (`home_url()`) and WordPress Address (`site_url()`) match, which is the widely common case. Configurations where these differ are often maintained by more advanced users, where this migration routine would be less essential - something to potentially iterate on in the future though.
* The migration does not actually update content in the database. More savvy users that prefer to do that can prevent the migration logic from running by either deleting the `https_migration_required` option or using the new `wp_should_replace_insecure_home_url` filter.
* For fresh sites that do not have any content yet at the point of changing the URLs to HTTPS, the migration will also be skipped since it would not be relevant.
* Expose a primary action in the Site Health recommendation, if HTTPS is already supported by the environment, built on top of the HTTPS detection mechanism from [49904]. When clicked, the default behavior is to update `home_url()` and `site_url()` in one go to their HTTPS counterpart.
* A new `wp_update_urls_to_https()` function takes care of the update routine.
* A new `update_https` meta capability is introduced to control access.
* If the site's URLs are controlled by constants, this update is not automatically possible, so in these scenarios the user is informed about that in the HTTPS status check in Site Health.
* Allow hosting providers to modify the URLs linked to in the HTTPS status check in Site Health, similar to how that is possible for the URLs around updating the PHP version.
* A `WP_UPDATE_HTTPS_URL` environment variable or `wp_update_https_url` filter can be used to provide a custom URL with guidance about updating the site to use HTTPS.
* A `WP_DIRECT_UPDATE_HTTPS_URL` environment variable or `wp_direct_update_https_url` filter can be used to provide a custom URL for the primary CTA to update the site to use HTTPS.

This changeset introduces a filter-based Robots API, providing central control over the `robots` meta tag.
* Introduces `wp_robots()` function which should be called anywhere a `robots` meta tag should be included.
* Introduces `wp_robots` filter which allows adding or modifying directives for the `robots` meta tag. The `wp_robots()` function is entirely filter-based, i.e. if no filter is added to `wp_robots`, no directives will be present, and therefore the entire `robots` meta tag will be omitted.
* Introduces the following `wp_robots` filter functions which replace similar existing functions that were manually rendering a `robots` meta tag:
* `wp_robots_noindex()` replaces `noindex()`, which has been deprecated.
* `wp_robots_no_robots()` replaces `wp_no_robots()`, which has been deprecated.
* `wp_robots_sensitive_page()` replaces `wp_sensitive_page_meta()`, which has been deprecated. Its rendering of the `referrer` meta tag has been moved to another new function `wp_strict_cross_origin_referrer()`.
Migration to the new functions is straightforward. For example, a call to `add_action( 'wp_head', 'wp_no_robots' )` should be replaced with `add_filter( 'wp_robots', 'wp_robots_no_robots' )`.
Plugins and themes that render their own `robots` meta tags are encouraged to switch to rely on the `wp_robots` filter in order to use the central management layer now provided by WordPress core.
