Message:

Multisite: Introduce the WP_Network class.

A WP_Network object initially matches a row from wp_site and is populated with additional properties used by WordPress core. The first iteration is used to retrieve an existing network based on data passed to the class.

• A network can be retrieved by its ID through WP_Network::get_instance(), following in the steps of WP_Post and WP_Comment.
• A network object can be created or completed by passing initial properties in as a standard object to new WP_Network().

Using these methods, we are now able to populate the global $current_site during load via this class.
