r49212 greatly improved the performance of `get_dirsize()`, but also changed the structure of the data stored in the `dirsize_cache` transient. It stored relative paths instead of absolute ones, and also removed the unnecessary `size` array.
That difference in data structures led to a fatal error in the following environment:
* PHP 8
* Multisite
* A custom `WP_CONTENT_DIR` which is not a child of WP's `ABSPATH` folder (e.g., [https://roots.io/bedrock/ Bedrock])
* The `upload_space_check_disabled` option set to `0`
After upgrading to WP 5.6, the `dirsize_cache` transient still had data in the old format. When `wp-admin.php/index.php` was visited, `get_space_used()` received an `array` instead of an `int`, and tried to divide it by another `int`. PHP 7 would silently cast the arguments to match data types, but [https://wiki.php.net/rfc/arithmetic_operator_type_checks PHP 8 throws a fatal error]:
`Uncaught TypeError: Unsupported operand types: array / int`
`recurse_dirsize()` was using `ABSPATH` to convert the absolute paths to relative ones, but some upload locations are not located under `ABSPATH`. In those cases, `$directory` and `$cache_path` were identical, and that triggered the early return of the old `array`, instead of the expected `int`.
In order to avoid that, this commit restores the absolute paths, but without the `size` array. It also adds a type check when returning cached values. Using absolute paths without `size` has the result of overwriting the old data, so that it matches the new format. The type check and upgrade routine are additional safety measures.

* Adds a message if a version control system has been detected, as automatic updates are disabled in that case.
* Ensures only one heading between `update available`, `you are on a dev version`, and `you are on latest` appears at any given time, falling back to `you are on latest` if something strange happens with the returned update data.
* Removes some older strings related to auto-updates, which greatly simplifies the above.
* Strips the `core-major-auto-updates-saved` query arg from the URL, as it is related to a dismissible notice.

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.

Instead of one cache entry for all upload folders for a site on multisite, this now caches for each folder and invalidates that cache based on context. In multisite, this should speed up `get_dirsize` calls since older directories that are much less likely to change will no longer have the size recalculated.

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()`

This allows for edits to be made to a restored post before it goes live again. This also prevents scheduled posts being published unexpectedly if they are untrashed after their originally scheduled date.
The old behaviour of restoring untrashed posts to their original status can be reinstated using the `wp_untrash_post_set_previous_status()` helper function.
Also fixes an issue where the incorrect post ID gets passed to hooks if no post ID is passed to the function.

For a number of years, most of the WordPress error messages have been prefixed with "Error:". However, these messages appear in a context where it's already clear an error occurred. Whether it's an error, a warning, or any other classification, that's not so relevant for users. The content of the message is the relevant part. The "Error:" prefix doesn't add great value while it does add unnecessary complexity for the message readability.
Also, revises some of these messages to improve clarity and removes HTML from translatable strings.

Previously, `wp_favicon_request()` was introduced in [13205] to avoid a performance hit of serving a full 404 page on every favicon request.
While working as intended, that implementation did not provide a way for theme or plugin authors to manage the behavior of favicon requests.
This changeset implements the following logic (only applied if WordPress is installed in the root directory):
* If there is a Site Icon set in Customizer, redirect `/favicon.ico` requests to that icon.
* Otherwise, use the WordPress logo as a default icon.
* If a physical `/favicon.ico` file exists, do nothing, let the server handle the request.
Handling `/favicon.ico` is now more consistent with handling `/robots.txt` requests.
New functions and hooks:
* Introduce `is_favicon()` conditional tag to complement `is_robots()`.
* Introduce `do_favicon` action to complement `do_robots` and use it in template loader.
* Introduce `do_favicon()` function, hooked to the above action by default, to complement `do_robots()`.
* Introduce `do_faviconico` action to complement `do_robotstxt`, for plugins to override the default behavior.
* Mark `wp_favicon_request()` as deprecated in favor of `do_favicon()`.
