On the Multisite - single site "Add New User" screen, some form fields have more
than one label associated with them. Form controls should have at most one
associated label element. If more than one label element is associated to the
control, assistive technologies may not read the appropriate label.
Additionally, labels can be associated to their related form fields either
explicitly (using a `for` attribute referencing the field ID) or implicitly
(using the label to wrap the field). As a best practice, never do both and
prefer explicitly associated labels when possible.
Props Ankit K Gupta.

`wp_load_translations_early()` is used when WordPress isn't fully initialized. Therefore using the `WP_Locale_Switcher` with `get_locale()`/`get_user_locale()` can cause PHP fatal errors.
This reverts [38976] and [38977], and instead removes `WP_Locale_Switcher` from `wp_load_translations_early()`.
See #29783.

* Hides page numbers visually at smaller screen sizes.
* Reduced padding around `.wrap` class on smaller screens.
* Fixed issue with the page numbers not displaying the underline on `:hover`. This has been updated in the custom colors files, too.

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.

* Rename customizer JS files to customize-preview.js and customize-controls.js to align with the core file naming and make it clearer where each file runs.
* Only show the colorscheme_hue control when there's a custom color scheme.
* Update preview JS handling for revised front page section handling, see below.
* Remove all references to "Theme Customizer" in code comments. It hasn't been called that since before 4.0.
* Clarify the purpose of the JS files by updated the code comments in the file headers.
* Improve code readability.
* Make the arbitrary number of front page sections filterable, for UI registration and output.
* Rename twentyseventeen_sanitize_layout to twentyseventeen_sanitize_page_layout to be clearer about what it sanitizes in case child themes or plugins consider reusing it.
* Rename page_options setting/control to page_layout as that's more reflective of what that option does; and again, helps for potential extensions.
* Make the page layout option contextual to pages and the sidebar being inactive, as the option only applies when there is no sidebar (per its description).
* Condense options into a single section.
* Add selective refresh for front page sections.
* Locate active_callback functions within customizer.php so that they're easier to find when editing customizer registrations, similarly to sanitize callbacks.
* Adjust the styling for placeholders for panels that aren't active.
* Ensure that the new visible edit shortcuts don't have any issues.

This adds the ability for themes to add support for videos in custom headers
by passing `'video' => true` as an argument when adding theme support for
custom headers.
Custom video headers are managed through the “Header Visuals” (i.e. “Header Image”)
panel in the Customizer where you can select a video from the media library or set a
URL to an external video (YouTube for now) for use in custom headers.
This introduces several new functions:
`has_header_video()` – Check whether a header video is set or not.
`get_header_video_url()` – Retrieve header video URL for custom header.
`the_header_video_url()` – Display header video URL.
`get_header_video_settings()` – Retrieve header video settings.
`has_custom_header()` – Check whether a custom header is set or not.
`get_custom_header_markup()` – Retrieve the markup for a custom header.
`the_custom_header_markup()` – Print the markup for a custom header.
And a new file, `wp-includes/js/wp-custom-header.js` that handles loading videos
in custom headers.
This also enables video headers in the Twenty Seventeen and Twenty Fourteen themes.

CSS generated content is going to be rendered for speech output more and more in
the next future. When it's not intended to be available for speech output, for
example with font icons, then special care should be used to hide it from
assistive technologies. At the moment, the only reliable way to do this is making
use of a wrapper element and set `aria-hidden="true"` on it.

A `null` value is returned in the response for any option that has a non-scalar value.
To protect clients from accidentally including the `null` values from a response object in a request, we do not allow options with non-scalar values to be updated to `null`. Without this added protection a client could mistakenly delete all options that have non-scalar values from the database.
