Featured image support means that attachments can now be imported. Media can be sideloaded from within theme or plugin directories. Like other posts, attachments are auto-drafts until customizer changes are published, and are not duplicated when they already exist in the customized state. Attachment IDs can be used for any number of purposes, much like post IDs. Twenty Seventeen now includes 3 images used as featured images to best showcase the multi-section homepage setup.
As featured image IDs are stored in post meta, it also made sense to add support for page templates. Twenty Seventeen does not include any such templates, but the functionality can be quite important for displaying themes to their best effect.

This adds play/pause controls to video headers, along with voice
assistance, using `wp.a11y.speak`, to make custom video headers more
accessible. To make styling the play/pause button easier for themes,
CSS has been omitted from the default implementation.
This also includes a refactor of the `wp.customHeader` code to introduce
a `BaseHandler` class, which can be extended by plugins and themes to modify
or enhance the default video handlers.

Adds a callback for determining when video headers should be displayed in themes supporting custom headers. By default, video headers are only displayed on the front page of a site.
Theme authors may set a custom callback by passing `'video-active-callback' => 'mytheme_video_active_callback'` as an argument. The default callback is `is_front_page()`.
This introduces the new function `is_header_video_active()` - returns `true` on pages that should display video headers. The return value can be filtered using the new filter of the same name.

When a user is not associated with a given setting change, continue to override `capability` to be `exist` when saving.

This is a great goal for core, and is close, but it is not in shape to be shipped for 4.7 and there is not enough time left in the development cycle to alter and polish sufficiently.

When themes register default headers, they can use sprintf style placeholder
strings in place of the template directory URI, which WordPress transforms
in several places by running the value of
`get_theme_support( 'custom-header', 'default-image' )` through `sprintf()`.
This fixes a few places where WordPress skipped the `sprintf()` step and
referenced the `get_theme_support()` value directly.

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.

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 is managed in customizer via a new "Additional CSS" section with a single `textarea` control.

If there are no pages when the customizer is opened, the `static_front_page` section will be hidden. As soon as a page is created in the customizer session, the `static_front_page` section will be revealed. Previously the section would not be registered if there were no pages. Page stubs created via nav menus will appear in the `dropdown-pages` controls for `page_for_posts` and `page_on_front`, and such page stubs will thus cause the `static_front_page` section to appear. Plugins that facilitate page creation in the customizer by filtering `get_pages` will also cause the section to appear.
