This function can be used to easily get the main site ID of a given network via the optional `$network_id` parameter, which defaults to the current network. The existing `is_main_site()` now uses the new function internally and now accepts an optional `$network_id` parameter as well.
The main purpose of the new function at this point is to ensure that the `WP_Network::$blog_id` property is always set. Magic getters in the class have been adjusted to auto-fill the property when it is accessed and empty. Furthermore the function encapsulates logic that was previously part of `ms_load_current_site_and_network()` and has been replaced with a call to the function now.

"Install" is not a noun, and while it might be acceptable to use the verb as a noun, it is not correct. Using the correct
noun, "installation", increases clarity, especially for non-native English speakers.
This change fixes the usage in user-facing text and in developer documentation.

Prior to about 2013, many class methods lacked even access modifiers which made the `@access` notations that much more useful. Now that we've gotten to a point where the codebase is more mature from a maintenance perspective and we can finally remove these notations. Notable exceptions to this change include standalone functions notated as private as well as some classes still considered to represent "private" APIs.

* Add magic `__get()`, `__set()`, and `__isset()` methods to `WP_Site` and `WP_Network.
* Provide `(int) $network->site_id` for `(string) $network->blog_id`
* Provide `(int) $site->id` for `(string) $site->blog_id`
* Provide `(int) $site->network_id` for `(string) $site->site_id`

Move the internals of `get_network_by_path()` to `WP_Network()` and allow network objects to be retrieved by passing a requested domain and path.

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.
