f9a5f5485d I18N: Allow the login screen language to be specified via a wp_lang query variable, and use this for the interim login modal. 
This allows users who are using the admin area in a language other than the site language to read the notice on the login screen
(which explains that they need to log in again) in their chosen language.

807bc5a6c9 Users: Introduce the concept of a large site in order to speed up the Users screen when there are many users. 
Calling the `count_users()` function is expensive, regardless of the counting strategy that's used, and it gets
slower the more users there are on a site. In order to speed up the Users screen in the admin area, calling
`count_users()` can be avoided entirely while still displaying the total count for users.

This introduces some new functions:

* `wp_is_large_user_count()`
* `wp_get_active_user_count()`
* `wp_update_active_user_count()`

A corresponding `wp_is_large_user_count` filter is also introduced.

f2d9abd022 Multisite: Introduce get_main_site_id(). 
This function can be used to easily get the main site ID of a given network via the optional `$network_id` parameter, which defaults to the current network. The existing `is_main_site()` now uses the new function internally and now accepts an optional `$network_id` parameter as well.

The main purpose of the new function at this point is to ensure that the `WP_Network::$blog_id` property is always set. Magic getters in the class have been adjusted to auto-fill the property when it is accessed and empty. Furthermore the function encapsulates logic that was previously part of `ms_load_current_site_and_network()` and has been replaced with a call to the function now.

28eda6f4bc General: Improve terminology used when referring to installations of WordPress and its extensions. 
"Install" is not a noun, and while it might be acceptable to use the verb as a noun, it is not correct. Using the correct
noun, "installation", increases clarity, especially for non-native English speakers.

This change fixes the usage in user-facing text and in developer documentation.

8eff927823 Media: Improve image filetype checking. 
This adds a new function `wp_get_image_mime()` which is used by
`wp_check_filetype_and_ext()` to validate image files using
`exif_imagetype()` if available instead of `getimagesize()`.

`getimagesize()` is less performant than `exif_imagetype()` and is
dependent on GD. If `exif_imagetype()` is not available, it falls back to
`getimagesize()` as before.

If `wp_check_filetype_and_ext()` can't validate the filetype, we now return
`false` for ext/MIME values.

75535c596b Customize: Introduce starter content and site freshness state. 
A theme can opt-in for tailored starter content to apply to the customizer when previewing the theme on a fresh install, when `fresh_site` is at its initial `1` value. Starter content is staged in the customizer and does not go live unless the changes are published. Initial starter content is added to Twenty Seventeen.

* The `fresh_site` flag is cleared when a published post or page is saved, when widgets are modified, or when the customizer state is saved.
* Starter content is registered via `starter-content` theme support, where the argument is an array containing `widgets`, `posts`, `nav_menus`, `options`, and `theme_mods`. Posts/pages in starter content are created with the `auto-draft` status, re-using the page/post stubs feature added to nav menus and the static front page controls.
* A `get_theme_starter_content` filter allows for plugins to extend a theme's starter content.
* Starter content in themes can/should re-use existing starter content items in core by using named placeholders.
* Import theme starter content into customized state when fresh site.
* Prevent original_title differences from causing refreshes if title is present.
* Ensure nav menu item url is set according to object when previewing.
* Make sure initial saved state is false if there are dirty settings without an existing changeset.
* Ensure dirty settings are cleaned upon changeset publishing.

In addition to `wp_list_filter()` for filtering a list of objects, and `wp_list_pluck()` for plucking a certain field out of each object in a list, this new function can be used for sorting a list of objects by specific fields.

This was previously committed in [38859] but got reverted in [38862] and [38863]. To fix the previous issues, `wp_list_sort()` supports now an additional argument to preserve array keys via `uasort()`.

e4a7c0a397 REST API: Introduce the Content API endpoints. 
REST API endpoints for your WordPress content. These endpoints provide machine-readable external access to your WordPress site with a clear, standards-driven interface, allowing new and innovative apps for interacting with your site. These endpoints support all of the following:
- Posts: Read and write access to all post data, for all types of post-based data, including pages and media.
- Comments: Read and write access to all comment data. This includes pingbacks and trackbacks.
- Terms: Read and write access to all term data.
- Users: Read and write access to all user data. This includes public access to some data for post authors.
- Meta: Read and write access to metadata for posts, comments, terms, and users, on an opt-in basis from plugins.
- Settings: Read and write access to settings, on an opt-in basis from plugins and core. This enables API management of key site content values that are technically stored in options, such as site title and byline.

Love your REST API, WordPress!  The infrastructure says, "Let's do lunch!" but the content API endpoints say, "You're paying!"

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.

ffdef38f5b Date/Time: Remove some legacy logic in date_i18n(). 
Since there's no difference between using `date()` and `gmdate()` in WordPress, we can simply use the former in `date_i18n()` to reduce its complexity.

Adds tests.

63664c1282 Multisite: Use get_networks() in get_main_network_id(). 
The manual query for the main network ID can now be replaced with a cached `get_networks()` query. This allows us to eliminate the `primary_network_id` cache key entirely.
