WordPress has historically often used code like `preg_split( '/[\s,]+/', $var )` to parse a string of comma-separated values into an array. However, this approach was causing an empty string to not be parsed into an empty array as expected, but rather into an array with the empty string as its sole element.
This was among other areas causing problems in the REST API where passing an empty request parameter could cause that request to fail because, instead of it being ignored, that parameter would be compared against the valid values for it, which typically do not include an empty string.

After [42832], [42891] and [43006], this changeset refines the core notice informing about an outdated PHP version:
* The link to the Update PHP information page can now be adjusted using either a `WP_UPDATE_PHP_URL` environment variable, or a new `wp_update_php_url` filter.
* If that URL is different from the default one that points to https://wordpress.org/support/update-php/ or its localized equivalent, a note indicates that the linked resource has not been provided by WordPress itself, and the default URL is still linked to as an additional resource.
* The URL for the default information page has been updated to use the slug `update-php` instead of `upgrade-php`.
* `@since` annotations have been updated.
Going forward, admin areas that display information related to the PHP version should use the new function `wp_get_update_php_url()`.

- Multiline function calls must now put each parameter on a new line.

Previously, personal data exports were stored in `wp-content/uploads/exports`, which is generic enough that it's likely there are existing folders with that name, either created by plugins or manually by administrators. If that folder were reused by Core, then `wp_privacy_delete_old_export_files()` would delete all of the existing files inside it, which is almost certainly not what the site owner wants or expects.
To avoid that, the folder is being renamed to include a specific reference to Core, and a more verbose description of its purpose. With those factored in, it's very unlikely that there will be any conflicts with existing folders.
The `wp_privacy_exports_dir()` and `wp_privacy_exports_url()` functions were introduced to provide a canonical source for the location, and the `wp_privacy_exports_dir` and `wp_privacy_exports_url` filters were introduced to allow plugins to customize it.

Previously, when a plugin updated its suggested privacy policy text, an admin notice was shown on all screens in the Administration Panels. That was done in order to make sure that administrators were aware of it, so that they could update their policy if needed. That was a very heavy-handed and intrusive approach, though, which leads to a poor user experience, and notice fatigue.
An alternative approach is to use bubble notifications in the menu, similar to when plugins have updates that need to be installed. That still makes it obvious that something needs the administrator's attention, but is not as distracting as a notice.
The notice will still appear on the Privacy page, though, since it is relevant to that screen, and provides an explanation of why the bubble is appearing.

When it did run in that context, it created a database error, because the necessary database tables don't exist at that point.
Checking the current context and returning early during the installation phase avoids that issue.

The primary means of protecting the files is the CSPRN appended to the filename, but there is no reason to keep the files after the data subject has downloaded them, so deleting them provides an additional layer of protection. Previously this was done from `wp_privacy_generate_personal_data_export_file()`, but that does not guarantee that it will be run regularly, and on smaller sites that could result in export files being exposed for much longer than necessary.
`wp_privacy_delete_old_export_files()` was moved to a front end file, so that it can be called from `cron.php`.
This introduces the `wp_privacy_export_expiration` filter, which allows plugins to customize how long the exports are kept before being deleted.
`index.html` was added to the `$exclusions` parameter of `list_files()` to make sure that it isn't deleted. If it were, then poorly-configured servers would allow the directory to be traversed, exposing all of the exported files.

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.

When the `WP_Network::$blog_id` property is set manually, for example in the multisite bootstrap process, `get_main_site_id()` should use that value instead of running its own logic. The main logic for the function was therefore moved into the internal `WP_Network::get_main_site_id()` method, which is now being accessed by the function through the magic property handling for `WP_Network::$blog_id` (and its equivalent `WP_Network::$site_id`).

Calling the `count_users()` function is expensive, regardless of the counting strategy that's used, and it gets
slower the more users there are on a site. In order to speed up the Users screen in the admin area, calling
`count_users()` can be avoided entirely while still displaying the total count for users.
This introduces some new functions:
* `wp_is_large_user_count()`
* `wp_get_active_user_count()`
* `wp_update_active_user_count()`
A corresponding `wp_is_large_user_count` filter is also introduced.

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.

`getimagesize()` as before.

A theme can opt-in for tailored starter content to apply to the customizer when previewing the theme on a fresh install, when `fresh_site` is at its initial `1` value. Starter content is staged in the customizer and does not go live unless the changes are published. Initial starter content is added to Twenty Seventeen.
* The `fresh_site` flag is cleared when a published post or page is saved, when widgets are modified, or when the customizer state is saved.
* Starter content is registered via `starter-content` theme support, where the argument is an array containing `widgets`, `posts`, `nav_menus`, `options`, and `theme_mods`. Posts/pages in starter content are created with the `auto-draft` status, re-using the page/post stubs feature added to nav menus and the static front page controls.
* A `get_theme_starter_content` filter allows for plugins to extend a theme's starter content.
* Starter content in themes can/should re-use existing starter content items in core by using named placeholders.
* Import theme starter content into customized state when fresh site.
* Prevent original_title differences from causing refreshes if title is present.
