This aims to make the update process more reliable and ensures that if a plugin or theme update fails, the previous version can be safely restored.
* When updating a plugin or theme, the old version is moved to a temporary backup directory:
* `wp-content/upgrade-temp-backup/plugins/[plugin-slug]` for plugins
* `wp-content/upgrade-temp-backup/themes/[theme-slug]` for themes.
* If the update fails, then the backup kept in the temporary backup directory is restored to its original location.
* If the update succeeds, the temporary backup is deleted.
To further help troubleshoot plugin and theme updates, two new checks were added to the Site Health screen:
* A check to make sure that the `upgrade-temp-backup` directory is writable.
* A check that there is enough disk space available to safely perform updates.
To avoid confusion: The temporary backup directory will NOT be used to “roll back” a plugin to a previous version after a completed update. This directory will simply contain a transient backup of the previous version of a plugin or theme being updated, and as soon as the update process finishes, the directory will be empty.

Per [https://developer.wordpress.org/coding-standards/wordpress-coding-standards/php/#writing-include-require-statements WordPress PHP coding standards], it is ''strongly recommended'' to use `require[_once]` for unconditional includes. When using `include[_once]`, PHP will throw a warning when the file is not found but will continue execution, which will almost certainly lead to other errors/warnings/notices being thrown if your application depends on the file loaded, potentially leading to security leaks. For that reason, `require[_once]` is generally the better choice as it will throw a `Fatal Error` if the file cannot be found.

This changeset implements a clearer and more consistent timeout/duration/expiration format. It updates time durations used in various files, as per WordPress coding standards:
- If the value can be represented as an integer (not a fractional) number of minutes (hours, etc.), use the appropriate constant (e.g.: `MINUTE_IN_SECONDS`) multiplied by that number.
- Otherwise, keep the value as is and add a comment with the units for clarity.

This allows third-party themes to avoid accidentally being overwritten with an update of a theme of a similar name from the WordPress.org Theme Directory.
Additionally, introduce the `update_themes_{$hostname}` filter, which third-party themes can use to offer updates for a given hostname.
If set, the `Update URI` header field should be a URI and have a unique hostname.
Some examples include:
* `https://wordpress.org/themes/example-theme/`
* `https://example.com/my-theme/`
* `my-custom-theme-name`
`Update URI: false` also works, and unless there is code handling the `false` hostname, the theme will never get an update notification.
If the header is present, the WordPress.org API will currently only return updates for the theme if it matches the following format:
* `https://wordpress.org/themes/{$slug}/`
* `w.org/theme/{$slug}`
If the header has any other value, the API will not return a result and will ignore the theme for update purposes.

Currently in WordPress multisite there is a concept of large networks. The function `wp_is_large_network` is used to determine if a network has a large number of sites or users. If a network is marked as large, then
expensive queries to calculate user counts are not run on page load but deferred to scheduled events. However there are a number of places in a single site installation where this functionality would also be useful, as
expensive calls to count users and roles can make screens in the admin extremely slow.
In this change, the `get_user_count` function and related functionality around it is ported to be available in a single site context. This means that expensive calls to the `count_users` function are replaced with
calls to `get_user_count`. This change also includes a new function called `wp_is_large_user_count` and a filter of the same name, to mark if a site is large.

The `get_core_checksums()` and `wp_version_check()` functions call the PHP native `http_build_query()` function, the second parameter of which is the ''optional'' `$numeric_prefix` parameter which expects a non-nullable `string`.
A parameter being optional, however, does not automatically make it nullable.
As of PHP 8.1, passing `null` to a non-nullable PHP native function will generate a deprecation notice.
In this case, this function call yielded a `http_build_query(): Passing null to parameter #2 ($numeric_prefix) of type string is deprecated` notice.
Changing the `null` to an empty string fixes this without a backward compatibility break.

This change includes three notable additions:
- Multiline function calls must now put each parameter on a new line.
- Auto-formatting files is now part of the `grunt precommit` script.
- Auto-fixable coding standards issues will now cause Travis failures.

This code branch is responsible for running all autoupdates, including plugins and themes - which should run regardless of if there's a core autoupdate available.
This revert does not revert the `$timeout` changes, as these should still use cached data if it's available.
Ideally this should be decoupled from the core update check to allow background updates to operate even when the core update check is disabled or running more often than twice daily.

This change reduces the number of API calls which WordPress makes to api.wordpress.org during release windows.
Previously the background updates would run upon every core update transient refresh, however now they'll only run if there's an update available.
The change also increases the cache period for plugin & theme checks when running via the cron, from never-cache to 2 hours, which should hopefully reduce the number of needless API calls.

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.
