Message:

General: Add a way to specify a direct link for a user to update PHP.

A direct URL to where a user can update PHP for their website can now be specified in one of two ways:

• Defining the WP_DIRECT_UPDATE_PHP_URL environment variable.
• Returning a URL to the wp_direct_php_update_url filter.

When a URL is specified, an additional “Update PHP” button will be displayed at the bottom of the Core dashboard widget informing administrators that their site is running an outdated version of PHP (see [42832]).

Merges [44814] to the 5.1 branch.

Fixes #46074.
