* The array of network data returned from the `networks_pre_query` filter is assigned to the `networks` property of the current `WP_Network_Query` instance.
* The array of site data returned from the `sites_pre_query` filter is assigned to the `sites` property of the current `WP_Site_Query` instance.
This avoids the performance overhead of calling `WP_Network_Query::get_networks()` or `WP_Site_Query::get_sites()` twice: first when creating the object instance, then to retrieve the filtered results.
This also makes the filters a bit more consistent with other similar filters, e.g. `posts_pre_query`, `terms_pre_query`, `comments_pre_query`, or `users_pre_query`.
Follow-up to [46086], [48990].

Improve the `pre_query` filters in multisite classes introduced in r44983. Return (non null) values immediately,
avoiding the database queries entirely, similar to other `pre_query` filters.

Similar to the `posts_pre_query` filter for WP_Query added in #36687. These filters lets you short circuit the queries to return your own results.
Add a new filter `sites_pre_query` - which returns null by default. Return a non-null value to bypass WordPress's default `get_sites` queries.
Developers should note that filtering functions that require pagination information are encouraged to set the `found_sites` property of the `WP_Site_Query` object, passed to the filter by reference. If `WP_Site_Query` does not perform a database query, it will not have enough information to generate these values itself.
Add a new filter `networks_pre_query` - which returns null by default. Return a non-null value to bypass WordPress's default `get_networks` queries.

This fixes an issue introduced in [44166] where the `$groupby` variable was inserted too low in the `get_site_ids()` function while merging [43832] into `trunk`. The merged location did not account for a new conditional statement that existed only in `trunk`, and would have resulted in values assigned to `$groupby` being erased in certain scenarios.
Props spacedmonkey.

A new global multisite table `wp_blogmeta` is added to the database schema, and a set of `*_site_meta()` API functions are introduced.
The implementation fails gracefully when the new table is not yet available, which may happen especially shortly after the core update, before the network has been upgraded to the new database schema. The presence of the table is detected once and stored as a global setting on the main network.
Core does not yet use site metadata, but there are several use-cases to be implemented or explored in the near future, and it allows plugins to extend sites with arbitrary data, which will come in particularly handy with the upcoming REST API endpoint for sites.

In [25548], the `archived` column in `wp_blogs` was changed from `ENUM` to `TINYINT` to match other status fields. When `WP_Site_Query` was written later, it used `%d` as a placeholder when formatting the archived status.
It is possible that this query will fail for any installations that did not update the schema for `wp_blogs` as only single quoted values are accepted for the `ENUM` type. In this case, `'0'` or `'1'` rather than `0` or `1`.
We can work around this and support both `ENUM` and `TINYINT` in the query by using the `%s` placeholder and casting the value with `absint()`.

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.

One thing fairly common to the cache groups is a block of code to look to see when the cache was last changed, and if there isn't one, to set it for the current microtime(). It appears in 8 different places in core. This adds a new helper `wp_cache_get_last_changed` to DRY things up a bit.
Since `wp-includes/cache.php` isn't guaranteed to be loaded, this new function is in `wp-includes/functions.php`

Previously, `compact()` provided a non existent `$join` and could cause confusion for anyone attempting to extend `WP_Site_Query` with their own tables. This aligns with the current behavior in `WP_Network_Query`.
