Sergey Biryukov 47ed56f38f Code Modernization: Replace `dirname( __FILE__ )` calls with `__DIR__` magic constant.
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`

johnjamesjacoby b65ea119bb Multisite/Sites: Add links to filter websites by status.
This commit brings the Network-Admin Sites list page up-to-speed with other similar list-table powered pages, by adding links to filter the results by Site Status.

Includes a single unit test for the newly introduced `wp_count_sites()` multisite function, named to match the `wp_count_` function pattern from other list tables.

Sergey Biryukov 16b8d91baa I18N: Improve translator comments.
* Add missing translator comments.
* Fix placement of some translator comments. Translator comments should be on the line directly above the line containing the translation function call for optimal compatibility with various `.pot` file generation tools. The CS auto-fixing, which changed some inconsistent function calls to multi-line function calls, is part of the reason why this was no longer the case for a select group of translator comments.

Includes minor code layout fixes.

Polyglots, rejoice! All WordPress core files now have translator comments for all strings with placeholders!

Jeremy Felt 1560fbcbc5 Multisite: Use `get_network()` and `get_current_network_id()` for current network data.
`get_network()` falls back to the current network when called without any arguments. Between this and `get_current_network_id()`, we can replace almost all instances of the global `$current_site` and all instances of `get_current_site()`.

This effectively deprecates `get_current_site()`, something that we'll do in a future ticket.

Matt Thomas 5d5114daf9 Bring the install/update screens in line with the new admin design. This affects:
* Creating a wp-config.php file
* Installation
* Database upgrade
* Database repair
* Readme.html
* Network sites actions

What's changed:

* Bring background/text/link/border colours in line with mp6
* Bring fonts in line with mp6 (see note below)
* Switch to device-width for the viewport and tweak margins etc so the layout works nicely on all device sizes
* Switch to the new vector WordPress logo in the header to match the log in screen
* Force table cells into rows in the <782px media query

Fixes #25951, props johnbillion.
