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.

Before this changeset, the language of a new site would always result in the language of the current network, regardless of the `$site_id` parameter passed that actually determines the network for the site. Now the correct `WPLANG` value is used in such cases.

That changeset is reverted here with the exception of the removal of the `is_super_admin()` check, which can safely be omitted.

The `get_user_count()` function returns the number of active users on a network, which is stored in a `user_count` network option. Since `get_network_option()` supports retrieving options from other networks than the current one, `get_user_count()` can now make use of that feature.

The `get_blog_count()` function used to support an `$id` parameter for the network ID prior to WordPress 3.1. This parameter has not been used since the introduction of `get_site_option()` and was later deprecated in [25113]. With `get_network_option()` however it is possible to support the parameter again, now properly renamed as `$network_id`.
A unit test has for the parameter has been added as well. Another unit test in the same class was adjusted to work properly with multiple networks existing.

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.

With the introduction of user-specific languages in [38705] it's necessary to be able to switch translations on the fly. For example emails should be sent in the language of the recipient and not the one of the current user.
This introduces a new `WP_Locale_Switcher` class which is used for switching locales and translations. It holds the stack of locales whenever `switch_to_locale( $locale )` is called. With `restore_previous_locale()` you can restore the previous locale. `restore_current_locale()` empties the stack and sets the locale back to the initial value.
`switch_to_locale()` is added to most of core's email functions, either with the value of `get_locale()` (site language) or `get_user_locale()` (user language with fallback to site language).

The `WP_INSTALLING` constant is a flag that WordPress sets in a number of
places, telling the system that options should be fetched directly from the
database instead of from the cache, that WP should not ping wordpress.org for
updates, that the normal "not installed" checks should be bypassed, and so on.
A constant is generally necessary for this purpose, because the flag is
typically set before the WP bootstrap, meaning that WP functions are not yet
available. However, it is possible - notably, during `wpmu_create_blog()` -
for the "installing" flag to be set after WP has already loaded. In these
cases, `WP_INSTALLING` would be set for the remainder of the process, since
there's no way to change a constant once it's defined. This, in turn, polluted
later function calls that ought to have been outside the scope of site
creation, particularly the non-caching of option data. The problem was
particularly evident in the case of the automated tests, where `WP_INSTALLING`
was set the first time a site was created, and remained set for the rest of the
suite.
The new `wp_installing()` function allows developers to fetch the current
installation status (when called without any arguments) or to set the
installation status (when called with a boolean `true` or `false`). Use of
the `WP_INSTALLING` constant is still supported; `wp_installing()` will default
to `true` if the constant is defined during the bootstrap.

Our call to `$wp_roles->_init()` relied on the `__call()` method in `WP_Roles` to handle the link to the protected method. This works back to PHP 5.2.9, when a bug was fixed allowing access to protected methods through this exact approach.
`install_blog()` needs a fresh `$wp_roles` object after `populate_roles()` resets everything in its path. We can create this new object from scratch, effectively doing the same thing with the call to `_init()` via the constructor.
