Sergey Biryukov cb2d81f6df Coding Standards: Restore the `$pieces` variable for SQL clauses in query classes.
This is a defensive coding measure that aims to reduce confusion. With this change, `$pieces` is explicitly used for the names, and `$clauses` for the values of the clauses.

Sergey Biryukov e333f174de Code Modernization: Rename parameters that use reserved keywords in `wp-includes/class-wp-site-query.php`.
While using reserved PHP keywords as parameter name labels is allowed, in the context of function calls using named parameters in PHP 8.0+, this will easily lead to confusion. To avoid that, it is recommended not to use reserved keywords as function parameter names.

This commit renames the `$string` parameter to `$search` in `WP_Site_Query::get_search_sql()`.

Sergey Biryukov 4a18c93f42 Networks and Sites: Assign the array of site or network data returned from filters to the respective class property:
* 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`.

Adam Silverstein cd67264bb2 Multisite: add new `sites_pre_query` and `networks_pre_query` filters to short circuit WP_Site_Query and WP_Network_Query queries.
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.

Felix Arntz 176a289050 Multisite: Introduce metadata for sites.
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.

Jeremy Felt 7e190e496b Multisite: Use `%s` when building query for `archived` sites in `WP_Site_Query`.
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()`.

Props stephdau.

Drew Jaynes 0860bb2771 Docs: Remove `@access` notations from method DocBlocks in wp-includes/* classes.
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.

See #41452.

Felix Arntz af50e8eb2c Multisite: Improve caching in `WP_Site_Query` by ignoring the `$fields` argument.
Prior to this change there were two different cache keys used for the same query. That is because regardless of the `$fields` argument, the query response will be the same.

Aaron Jorbin 82911b1756 Cache API: introduce wp_cache_get_last_changed to improve DRY
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`

Props spacedmonkey, desrosj.
