By providing distinct files for the site and network APIs, a better overview is provided. Prior to this change, the `ms-blogs.php` file had grown too big, mixing site APIs, network APIs and related legacy APIs that need to be maintained. Since multisite is often used in unexpected ways, backward-compatibility is ensured by including the two new files from `ms-blogs.php`, which previously contained all functions that have been moved to the new files. This changeset does not contain any functional changes. Fixes #40647. Built from https://develop.svn.wordpress.org/trunk@44472 git-svn-id: http://core.svn.wordpress.org/trunk@44303 1a063a9b-81f0-0310-95a4-ce76da25c4cd
