WordPress creates attachment pages by default for every attachment uploaded. On the vast majority of sites, these attachment pages don't contain any meaningful information. They do however exist, get indexed by search engines, and sometimes even rank in search results, leading to bad results for users and site owners.
This commit introduces a `wp_attachment_pages_enabled` database option to control the attachment pages behavior:
* On existing sites, the option is set to `1` on upgrade, so that attachment pages continue to work as is.
* For new sites, the option is set to to `0` by default, which means attachment pages are redirected to the attachment URL.
* Sites that want to enable or disable the attachment pages can set the option to `1` or `0`, respectively.

Global terms was a feature from the WordPress MU days where multisite and single site installs used different code bases.
In WordPress 3.0, WordPress MU was merged into one location and the UI [14854] and “on” switch [14880] for global terms were completely removed.
Even before this merge, global terms was bug infested and unreliable. After [14854]/[14880], the feature was no longer maintained and became increasingly broken as taxonomies progressed without it (term splitting and term meta do not work at all). At this point, the feature has not worked in 12+ years and there’s no hope for saving it.
This deprecates the remaining global terms related code and no-ops the functions.
Global terms, you don’t have to go home, but you can’t stay here.

This fixes a bug where if the default `timezone_string` is set to a deprecated timezone name due to a localization providing an outdated timezone name string, this localized timezone string would be discarded and an empty string would be set as the timezone value instead.
By passing the `DateTimeZone::ALL_WITH_BC` constant as the `$timezoneGroup` parameter to the PHP native `timezone_identifiers_list()` function, a timezone name list is retrieved containing both current and deprecated timezone names, preventing the invalidation of the option value.
See the extensive write-up about this in ticket #56468.
Also see: [https://www.php.net/manual/en/datetimezone.listidentifiers.php PHP Manual: timezone_identifiers_list()].
Includes:
* Expanding the translators comment to encourage translators to use “old” names over “new” names.
* Adding a dedicated test to the `Tests_Admin_IncludesSchema` test class.

This changeset replaces the default "Just another WordPress site" tagline with an empty string for new installations. The reasoning is:
1. Not all themes display the tagline;
2. Not everyone changes the default tagline;
3. When people don't see the tagline in their theme, they may not realize it is still visible in some places, like feeds.
The string "Just another WordPress site" and the related multisite string: "Just another {NETWORK} site" are now only used as a placeholder for the tagline admin option.

Currently in WordPress multisite there is a concept of large networks. The function `wp_is_large_network` is used to determine if a network has a large number of sites or users. If a network is marked as large, then
expensive queries to calculate user counts are not run on page load but deferred to scheduled events. However there are a number of places in a single site installation where this functionality would also be useful, as
expensive calls to count users and roles can make screens in the admin extremely slow.
In this change, the `get_user_count` function and related functionality around it is ported to be available in a single site context. This means that expensive calls to the `count_users` function are replaced with
calls to `get_user_count`. This change also includes a new function called `wp_is_large_user_count` and a filter of the same name, to mark if a site is large.

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.

This change adds a throttle mechanism to plugin and theme auto-update failure emails using similar logic to the email sent for a Core auto-update.
The first time a plugin or theme auto-update fails, the package and `new_version` will be tracked in the `auto_plugin_theme_update_emails` option. An email for this specific update attempt will not be resent.
However, if this update fails again and non-repeat failures or successful updates are also present, then the failure information will be included in that email (an email needs to be sent for the new events regardless).

“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.

As part of the continued effort to improve PHP compatibility, the following improvments are being made:
- Removing deprecated PHP `safe_mode` checks not found in bundled external libraries.
- Change the remaining `while` loops using `each()` to `foreach` loops.
- Prevent false positives from being flagged for the `sodium_compat` library being caused by loading this in a non-standard way.
- Add inline comments to not flag deprecated PHP directives in the getID3 library.

As part of the Multisite installation process, a `blog_versions` table is created. This table is never read from (except immediately prior to updating it), it's only ever inserted into or updated. It is not used to determine which blogs need to be upgraded.
This table was introduced in 3.0 when the WPMU schema was merged #11644 and it appears the table has never been used in core and is therefore redundant and may as well be removed.
