The task was previously used to ensure that `/*! This file is auto-generated */` comment is not included on front end as part of the inline emoji detection script.
As the `wp-emoji-loader.js` script is now included via `file_get_contents()` and `wp_print_inline_script_tag()` instead of `grunt-include` to simplify the logic, the task does not find anything to replace and is no longer necessary.
Additionally, include a line break before the `wp-emoji-loader.js` script content for better line wrapping.

To prevent potential false negatives, set `$error` to `null` initially, so we can better tell if it was ever changed during the sanitization and be able to better react if an empty string is added to it.
Additionally, and mainly for the sake of the Settings API at this point, add error messages to some `WP_Error` objects returned from `wpdb` methods that were previously causing the issues here.

`sanitize_key()` expects a string type for the given `key`. Passing any other data type to `strtolower()` can result in `E_WARNING: strtolower() expects parameter 1 to be string, array given`.
A check is added that if the key is not a string, the key is set to an empty string. For performance, the additional string processing is skipped if the key is an empty string.
This change maintains backwards-compatibility for valid string keys while fixing the bug of non-string keys.

* Prevent loading `wp-embed` script unconditionally on every page in favor of conditionally enqueueing when a post embed is detected. The `wp-embed` script is also explicitly marked as being in the footer group. Sites which currently disable post embed scripts from being enqueued via `remove_action( 'wp_head', 'wp_oembed_add_host_js' )` will continue to do so.
* Send a `ready` message from the host page to each post embed window in case the `iframe` loads before the `wp-embed` script does. When the `ready` message is received by the post embed window, it sends the same `height` message as it sends when it loads.
* Eliminate use of `grunt-include` to inject emoji script and the post embed script. Instead obtain the script contents via `file_get_contents()` (as is done elsewhere in core) and utilize `wp_print_inline_script_tag()`/`wp_get_inline_script_tag()` to construct out the script. This simplifies the logic and allows the running of src without `SCRIPT_DEBUG` enabled.
* For the embed code that users are provided to copy for embedding outside of WP, add the `secret` on the `blockquote` and `iframe`. This ensures the `blockquote` will be hidden when the `iframe` loads. The embed code in question is accessed here via `get_post_embed_html()`.

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()`

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

The reason for introducing `wp_slash_strings_only()` in [46454] was to keep non-string values untouched.

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.

“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.
