The `term_exists()` check is not needed because of existing dupe
checks in `wp_insert_term()`. Furthermore, `term_exists()` conflates
term names and sanitized slugs, so incorrectly marks terms like
'C' and 'C+' as duplicates of one another.

In [38625], the functionality to search for attachments by filename was added
via the `posts_clauses` filter and the `_filter_query_attachment_filenames()`
function. This moves `_filter_query_attachment_filenames()` from
`wp-admin/includes/post.php` to `wp-includes/post.php` so that it can be
applied in the same manner in the REST API media endpoint.

Previously there was no way to remove the user locale setting again, even though that might be desirable.
This adds a new 'Site Default' option to the user-specific language setting by introducing a new `show_site_locale_default` argument to `wp_dropdown_languages()`.

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. There are bugs, but more than that, there are more fundamental questions around the use of existing UI, general UX, and how findable themes are (not) on the .org side.

Previously a user could remove a protected meta field by using their browser developer tools to alter the form field properties in the Custom Fields meta box, given that they know the ID of the protected meta field. This change prevents this by preventing any change to a protected meta field, including changing its key.

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.

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).

WordPress has supported custom page templates for over 12 years, allowing developers to create various layouts for specific pages.
While this feature is very helpful, it has always been limited to the 'page' post type and not was not available to other post types.
By opening up the page template functionality to all post types, we continue to improve the template hierarchy's flexibility.
In addition to the `Template Name` file header, the post types supported by a template can be specified using `Template Post Type: post, foo, bar`.
When at least one template exists for a post type, the 'Post Attributes' meta box will be displayed in the back end, without the need to add post type support for `'page-attributes'`. 'Post Attributes' can be customized per post type using the `'attributes'` label when registering a post type.

When support for PDFs is available, on upload,
render 'Thumbnail', 'Medium', 'Large', and 'Full' sizes of
the first page, and save them in attachment meta.
Use these renders within Add Media, Media Gallery and List views,
Attachment Details, Post/Attachment Edit screens, and Attachment pages.
Support available by default via Imagick -> ImageMagick -> Ghostscript,
but can be provided by any `WP_Image_Editor` that supports PDFs.
