807bc5a6c9 Users: Introduce the concept of a large site in order to speed up the Users screen when there are many users.
Calling the `count_users()` function is expensive, regardless of the counting strategy that's used, and it gets
slower the more users there are on a site. In order to speed up the Users screen in the admin area, calling
`count_users()` can be avoided entirely while still displaying the total count for users.

This introduces some new functions:

* `wp_is_large_user_count()`
* `wp_get_active_user_count()`
* `wp_update_active_user_count()`

A corresponding `wp_is_large_user_count` filter is also introduced.

7e2ca92e69 Multisite: Introduce a can_add_user_to_blog filter to prevent adding a user to a site.
Under certain circumstances, it can be necessary that a user should not be added to a site, beyond the restrictions that WordPress core applies. With the new `can_add_user_to_blog` filter, plugin developers can run custom checks and return an error in case of a failure, that will prevent the user from being added.

The user-facing parts and the REST API route that interact with `add_user_to_blog()` have been adjusted accordingly to provide appropriate error feedback when a user could not be added to a site. Furthermore, two existing error feedback messages in the site admin's "New User" screen have been adjusted to properly show inside an error notice instead of a success notice.

2295ed8031 Multisite: Remove restriction of minimum site name length in wpmu_validate_blog_signup().
It is sometimes desirable to support shorter site names than 4 characters, therefore that restriction should be removed. It is still possible to manually enforce it by using the `wpmu_validate_blog_signup` filter.

As a result of this change, another `is_super_admin()` call gets removed which affects the ongoing efforts of working on a network-wide role system.

788761c601 Multisite: Rename the $user parameter to $user_login in wpmu_signup_blog_notification() and wpmu_signup_user_notification().
[38961] added a `$user = get_user_by( 'login', $user );` call which was overriding the `$user` string variable for the login name. The change to `$user_login` makes this clear.
