A static variable contains an integer that is incremented with each call. This number is returned with the optional prefix.
As such the returned value is not universally unique, but it is unique across the life of the PHP process.

Some versions of PHP appear to have a memory leak that is occasionally triggered by calling `stream_get_wrappers()`. In order to avoid calling this, we can return early from `wp_is_stream()` when `$path` doesn't contain `://`.

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.

r43046 introduced wp_schedule_delete_old_privacy_export_files() to schedule the wp_privacy_delete_old_export_files cron job, but it did not check to make sure it wasn't running in the context of the install process. 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.

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.
