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.

Previously, the `post_count` option value was not decremented when a post was deleted.
This change moves the `_update_posts_count_on_delete` action from `delete_post` hook to `after_delete_post` to ensure the deletion is taken into account.

When a user has registered with incorrect data and got the account deleted immediately, it currently wasn't possible to register with the same login or email address again due to the existing signup entry. They had to wait for two days until the entry gets automatically deleted. Now the associated signup entry gets deleted as part of the account deletion.

“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.

This changeset makes the new CRUD API for sites introduced in [43548] usable for real-world sites. A new function `wp_initialize_site()`, which takes care of creating a site's database tables and populating them with initial values, is hooked into the site insertion process that is initiated when calling `wp_insert_site()`. Similarly, a new function `wp_uninitialize_site()`, which takes care of dropping a site's database tables, is hooked into the site deletion process that is initiated when calling `wp_delete_site()`.
A new function `wp_is_site_initialized()` completes the API, allowing to check whether a site is initialized. Since this function always makes a database request in its default behavior, it should be called with caution. Plugins that would like to use site initialization in special ways can leverage a `pre_wp_is_site_initialized` filter to alter that default behavior.
The separate handling of the site's row in the `wp_blogs` database table and the actual site setup allows for more flexibility in controlling whether or how a site's data is set up. For example, a unit test that only checks data from the site's database table row can unhook the site initialization process to improve performance. At the same time, developers consuming the new sites API only need to know about the CRUD functions, since the initialization and uninitialization processes happen internally.
With this changeset, the foundation for a sites REST API endpoint is fully available. The previously recommended functions `wpmu_create_blog()` and `wpmu_delete_blog()` now call the new respective function internally. Further follow-up work to this includes replacing calls to `wpmu_create_blog()` with `wp_insert_site()`, `update_blog_details()` with `wp_update_site()` and `wpmu_delete_blog()` with `wp_delete_blog()` throughout the codebase.
As a side-effect of this work, the `wpmu_new_blog`, `delete_blog`, and `deleted_blog` actions and the `install_blog()` function have been deprecated.

New functions `wp_insert_site( $data )`, `wp_update_site( $id, $data )` and `wp_delete_site( $id )` are introduced to manage site rows in the `wp_blogs` table, forming the new CRUD API together with the existing `get_site()` / `get_sites()`. The new API provides various benefits over the previously existing API, fixing several cache invalidation issues and being hook-driven so that normalization and validation of the passed data can be fully customized.
New hooks introduced as part of this are the actions `wp_insert_site`, `wp_update_site`, `wp_delete_site`, `wp_validate_site_data` and the filter `wp_normalize_site_data`.
At this point, `wp_insert_site()` does not handle setting up the site's database tables, and `wp_delete_site()` does not handle dropping the site's database tables, so the two can not yet be used directly as full replacements of `wpmu_create_blog()` and `wpmu_delete_blog()`. Managing the site's database tables will be added via hooks as part of the follow-up ticket #41333.
The existing functions `wpmu_create_blog()`, `update_blog_details()`, and `wpmu_delete_blog()` make use of the respective new counterpart and will be obsolete once #41333 has been completed.

Switching the available roles and the current user's capabilities no longer happens in `switch_to_blog()` and `restore_current_blog()`, instead it has been moved to a new function `wp_switch_roles_and_user()` which is hooked into the site switching process. This allows to improve performance by temporarily unhooking the function when roles and capabilities do not need to be switched.
This change ensures that switching available roles now works closer to switching user capabilities, particularly the changes in [41624]. A new `WP_Roles::for_site( $site_id )` method has been introduced, and the `WP_Roles::_init()` method has been deprecated. It is furthermore possible to retrieve the site ID for which the available roles are currently initialized through a new `WP_Roles::get_site_id()`.

[40591] and [40593] introduced a `$network_id` parameter for `wp_maybe_update_network_site_counts()` and `wp_maybe_update_network_user_counts()`, as well as [40486] previously added it to `wp_update_network_counts()`. This changeset ensures the filter hooks in `ms-default-filters.php` do not pass any parameter to them that might conflict with their actual `$network_id` parameter, which caused unit test failures before.

Previously `update_blog_option()` would trigger an invalidation of that site's entire cache although these changes did not affect the content of these caches. Furthermore changes to the special options `blogname`, `siteurl` and `post_count` should not invalidate the entire cache of that site, but only their respective site details cache. The option `home` now has the same behavior as it also belongs to the site details, but did not invalidate the cache at all previously.
Several new unit tests confirm these changes work as expected.

When a new user is created in various places throughout the interface,
notifications are sent to the site admin and the new user. Previously, these
notifications were fired through direct calls to `wp_new_user_notification()`,
making it difficult to stop or modify the messages.
This changeset introduces a number of new action hooks in place of direct calls
to `wp_new_user_notification()`, and hooks the new wrapper function
`wp_send_new_user_notifications()` to these hooks.

* Check if the host is considered a safe redirect host.
* Check if the host is another domain in a multisite installation.
* Add a filter to control this.
This only occurs when the DNS resolution of a domain points elsewhere in an internal network, but only internally (and has its own public IP outside the network). This could be considered a bad configuration.
