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.

* The `[embed]` shortcode is not supported because there is no post context for caching oEmbed responses. This depends on #34115.
* Add `do_shortcode()` to the `widget_text_content` filter in the same way it is added for `the_content` at priority 11, with `shortcode_unautop()` called at priority 10 after `wpautop()`.
* For Text widget in legacy mode, manually apply `do_shortcode()` (and `shortcode_unautop()` if auto-paragraph checked) if the core-added `widget_text_content` filter remains, unless a plugin added `do_shortcode()` to `widget_text` to prevent applying shortcodes twice.
* Ensure that global `$post` is `null` while filters apply in the Text widget so shortcode handlers won't run with unexpected contexts.

The new meta capabilities are called `install_languages` and `update_languages`. Prior to this change, there were no proper capability checks applied. Instead only the filesystem and related constants were checked, and for actual permissions a rather vague fallback was used where a user needed to have at least one of the other updating capabilities. In addition to being generally more verbose, the new capabilities make it possible for example to allow a user to update languages, but nothing else. By default they fall back to the original way of how they were handled.

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.

With the introduction of user-specific languages in [38705] it's necessary to be able to switch translations on the fly. For example emails should be sent in the language of the recipient and not the one of the current user.
This introduces a new `WP_Locale_Switcher` class which is used for switching locales and translations. It holds the stack of locales whenever `switch_to_locale( $locale )` is called. With `restore_previous_locale()` you can restore the previous locale. `restore_current_locale()` empties the stack and sets the locale back to the initial value.
`switch_to_locale()` is added to most of core's email functions, either with the value of `get_locale()` (site language) or `get_user_locale()` (user language with fallback to site language).

Fixes bug where an invalid Last-Modified value would be returned in feed requests for sites that had 0 items to return. Comment or post feeds will now return the current timestamp as the Last-Modified header value. Example: a request for the comments feed for a site without any comments.
Replaced use of the local static variable `$cache_lastcommentmodified` to store the modified date in `get_lastcommentmodified()` with the Object Cache API. The `get_lastcommentmodified()` function returns early if there is a cached value and returns `false` if there where no comments found. Introduced `_clear_modified_cache_on_transition_comment_status()` to flush the `lastcommentmodified` cache key when a comment enters or leaves approval status.

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!"

Since 4.4, comment submission has been mostly abstracted into a function,
rather than being processed inline in wp-comments-post.php. This change
made it easier to write automated tests against the bulk of the comment
submission process. `wp_allow_comment()` remained untestable, however:
when a comment failed one of its checks (flooding, duplicates, etc),
`die()` or `wp_die()` would be called directly. This shortcoming posed
problems for any application attempting to use WP's comment verification
functions in an abstract way - from PHPUnit to the REST API.
The current changeset introduces a new parameter, `$avoid_die`, to the
`wp_new_comment()` stack. When set to `true`, `wp_new_comment()` and
`wp_allow_comment()` will return `WP_Error` objects when a comment check
fails. When set to `false` - the default, for backward compatibility -
a failed check will result in a `die()` or `wp_die()`, as appropriate.
Prior to this changeset, default comment flood checks took place in the
function `check_comment_flood_db()`, which was hooked to the
'check_comment_flood' action. This design allowed the default comment
flood routine to be bypassed or replaced using `remove_action()`.
In order to maintain backward compatibility with this usage, while
simultaneously converting the comment flood logic into something that
returns a value rather than calling `die()` directly,
`check_comment_flood_db()` has been changed into a wrapper function for
a call to `add_filter()`; this, in turn, adds the *actual* comment flood
check to a new filter, 'wp_is_comment_flood'. Note that direct calls
to `check_comment_flood_db()` will no longer do anything in isolation.

Arguments are whitelisted to reserve the right for core to add more later.
New functions added to complement this expansion are:
* `registered_meta_key_exists()`
* `unregister_meta_key()`
* `get_registered_meta_keys()`
* `get_registered_metadata()`
* A "private" function for the aforementioned whitelisting.

This adds three new functions for getting/displaying attachment captions:
* `wp_get_attachment_caption` - Retrieves a caption for a specific attachment.
* `get_the_post_thumbnail_caption()` - Returns the post thumbnail caption.
* `the_post_thumbnail_caption()` - Displays the post thumbnail caption.
These are helpful for displaying a caption associated with an image directly
in a template, rather than using the caption shortcode.
This also introduces two new filters:
* `wp_get_attachment_caption` - Filters the value of `wp_get_attachment_caption()`.
* `the_post_thumbnail_caption` - Filters the display of the post thumbnail caption.
`the_post_thumbnail_caption()` is automatically filtered by `wptexturize()`,
`convert_smilies()`, and `convert_chars()` in `wp-includes/default-filters.php`.

Prior to [23512], the Toolbar was still displayed on wp-signup.php while logged-in because it was hooked to the `init` action. When `_wp_admin_bar_init()` was moved to instead fire on `template_redirect` for the front-end and `admin_init` on the back-end, the visibility was lost because `template_redirect` isn't fired on wp-signup.php due to `WP_USE_THEMES` not being defined.
In order to maintain expected display results, a default filter has been added to hook `_wp_admin_bar_init()` to the `before_signup_header` action. This approach has the added benefit of allowing `_wp_admin_bar_init()` to be fired prior to the `wp_head` action where `_admin_bar_bump_cb()` is called (or the callback defined when 'admin-bar' theme support is added).

[34561] instituted the policy of forcing pagination for comments. This strategy
was intended to avert problems when 'page_comments' is set to 0 - as it is by
default - and the number of comments on a given post rises into the hundreds or
thousands. By forcing pagination in all cases, we ensured that WordPress would
not time out by processing unwieldy numbers of comments on a given pageload.
The strategy proves problematic, however, because comment permalinks are
generated using the page of the comment. Forcing pagination for posts that
were not previously paginated would change the URL of all comments that do not
appear on the default comment page.
This changeset reintroduces the 'page_comments' setting and its corresponding
checkbox on Settings > Discussion. A number of tests, which were written after
[34561], are modified to work now that 'page_comments' will, once again, be
disabled by default.
