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.

Site and user signup notifications are moved to the new actions
`'after_signup_site'` and `'after_signup_user'`. Site and user activation
notifications are moved to the existing actions `'wpmu_activate_blog'` and
`'wpmu_activate_user'`.

* 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.
