This avoids the performance overhead of the function call every time `dirname( __FILE__ )` was used instead of `__DIR__`.
This commit also includes:
* Removing unnecessary parentheses from `include`/`require` statements. These are language constructs, not function calls.
* Replacing `include` statements for several files with `require_once`, for consistency:
* `wp-admin/admin-header.php`
* `wp-admin/admin-footer.php`
* `wp-includes/version.php`

With this change, the result of a site or network lookup by ID will be cached even if the ID does not exist. When a new site or network is created, the cache for the respective new ID is cleared.

Prior to this change, querying sites early in the bootstrap process could potentially cause a fatal error, since at that stage the filter to bail on updating site meta cache if the respective database table has not been installed yet is not hooked in yet. This changeset forces the filter to be added if that is not already the case.
Props spacedmonkey.

Restores `public`, `archived`, `mature`, `spam`, `deleted`, `lang_id`, and `WPLANG` to the `$meta` data passed to `wpmu_new_blog`. This hook was deprecated in 5.1.0, but code using it still relies on this data.

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.
