This change prevents non-visible characters in titles from creating encoded values in permalinks, opting instead for the following replacement strategy:
* Non-visible non-zero-width characters are replaced with hyphens
* Non-visible zero-width characters are removed entirely
Included with this change are 64 additional PHPUnit assertions to confirm that only the targeted non-visible characters are sanitized as intended.
Before this change, URLs would unintentionally contain encoded values where these non-visible characters were. After this change, URLs intentionally strip out or hyphenate these non-visible characters.

This fixes `parse_str(): Passing null to parameter #1 ($string) of type string is deprecated` notices on PHP 8.1, without change in behaviour.
Impact: 311 of the pre-existing tests are affected by this issue.
The PHP native `parse_str()` function expects a string, however, based on the failing tests, it is clear there are functions in WordPress which passes a non-string – including `null` – value to the `wp_parse_str()` function, which would subsequently pass it onto the PHP native function without further input validation.
Most notable offender is the `wp_parse_args()` function which special cases arrays and objects, but passes everything else off to `wp_parse_str()`.
Several ways to fix this issue have been explored, including checking the received value with `is_string()` or `is_scalar()` before passing it off to the PHP native `parse_str()` function.
In the end it was decided against these in favor of a string cast as:
* `is_string()` would significantly change the behavior for anything non-string.
* `is_scalar()` up to a point as well, as it does not take objects with a `__toString()` method into account.
Executing a string cast on the received value before passing it on maintains the pre-existing behavior while still preventing the deprecation notice coming from PHP 8.1.

A general security rule is "Sanitize when you save, escape when you echo", and for the most part WordPress has well-named functions like `sanitize_email()` and others, with `esc_url_raw()` being a single exception that does not follow the naming.
This commit restores the previously deprecated `sanitize_url()` function as a valid alias of `esc_url_raw()`.
This better aligns with the naming with other `sanitize_*()` functions:
* `sanitize_bookmark()`
* `sanitize_bookmark_field()`
* `sanitize_category()`
* `sanitize_category_field()`
* `sanitize_comment_cookies()`
* `sanitize_email()`
* `sanitize_file_name()`
* `sanitize_hex_color()`
* `sanitize_hex_color_no_hash()`
* `sanitize_html_class()`
* `sanitize_key()`
* `sanitize_meta()`
* `sanitize_mime_type()`

* `sanitize_post()`
* `sanitize_post_field()`
* `sanitize_sql_orderby()`
* `sanitize_term()`
* `sanitize_term_field()`

When `noopener noreferrer` was originally added in #37941 and related tickets, the `noreferrer` bit was specifically included due to Firefox not supporting `noopener` at the time.
Since `noopener` has been supported by all major browsers for a while, it should now be safe to remove the `noreferrer` attribute from core.

Using the canonical function name for PHP functions is strongly recommended, as aliases may be deprecated or removed without (much) warning.
This replaces all uses of the following:
* `join()` with `implode()`
* `sizeof()` with `count()`
* `is_writeable()` with `is_writable()`
* `doubleval()` with a `(float)` cast
In part, this is a follow-up to #47746.

The reason for introducing `wp_slash_strings_only()` in [46454] was to keep non-string values untouched.
Later, `wp_slash()` itself was updated in [48433] to prevent changing non-string values.
To avoid confusion, `wp_slash_strings_only()` is now deprecated.

There are two pieces in here:
1) The update to change blacklist to blocklist is moved to disallowed_list. "Block" has a meaning in our code, and there could be ambiguity between this code and code related to blocks.
2) This improves backwards compatibility for code that was accessing the now deprecated code.

If a bool/float/int is passed into wp_slash it will be coerced into a string.
This changes the behavior to only slash strings. At the same time, handles recursion a little nicer by calling array_map for arrays.

The filter is the callback function added with `add_filter()`, therefore the hook passes a value to the filter, and the filter returns a value to change its behaviour.

“The WordPress open source community cares about diversity. We strive to maintain a welcoming environment where everyone can feel included.”
With this commit, all occurrences of “whitelist” and “blacklist” (with the single exception of the `$new_whitelist_options` global variable) are removed. A new ticket has been opened to explore renaming the `$new_whitelist_options` variable (#50434).
Changing to more specific names or rewording sentences containing these terms not only makes the code more inclusive, but also helps provide clarity. These terms are often ambiguous. What is being blocked or allowed is not always immediately clear. This can make it more difficult for non-native English speakers to read through the codebase.
Words matter. If one contributor feels more welcome because these terms are removed, this was worth the effort.

While web crawlers are able to discover pages from links within the site and from other sites, XML sitemaps supplement this approach by allowing crawlers to quickly and comprehensively identify all URLs included in the sitemap and learn other signals about those URLs using the associated metadata.
See https://make.wordpress.org/core/2020/06/10/merge-announcement-extensible-core-sitemaps/ for more details.
This feature exposes the sitemap index via `/wp-sitemap.xml` and exposes a variety of new filters and hooks for developers to modify the behavior. Users can disable sitemaps completely by turning off search engine visibility in WordPress admin.
This change also introduces a new `esc_xml()` function to escape strings for output in XML, as well as XML support to `wp_kses_normalize_entities()`.
