<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Multisite: Introduce `ms-site.php` and `ms-network.php` files.
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.
