7b0355b559 Script Loader: Use dns-prefetch for the Emoji CDN.
* `preconnect` will be potentially pretty heavy on the CDN. With the Unicode 9.0 emoji update, almost all browsers will trigger the `preconnect`.
* `preconnect` only opens one connection, but `s.w.org` is HTTP/1.1, so the browser will use the preconnected connection for the first emoji, then it has to open new connections for subsequent emoji.

Also use the same URL as we use for the `emoji_svg_url` filter. This will print the hint for the correct CDN in case someone uses a custom CDN.

3dbba0fff3 Post Thumbnails: Only update featured images when saving a post.
Previously, changing the post thumbnail of a published post in the edit screen
would immediately apply the change, rather than waiting for the post to be
saved before applying the update. This could lead to someone unintentionally
editing the post thumbnail on a published post, and made it impossible to
preview changes to post thumbnails on published posts before saving the change.

This introduces a new Ajax handler, `wp_ajax_get_post_thumbnail_html()` to
retrieve the HTML for the post thumbnail meta box without updating the post
meta value for `_thumbnail_id`. It also allows post thumbnail changes to be
previewed by passing the `_thumbnail_id` as a query variable to the preview
screen and adding a new filter, `_wp_preview_post_thumbnail_filter()`, which
gets applied to `get_post_metadata` during the post preview process.

efb315afb9 Media: Ensure empty alt attributes are set to blank strings.
This is a follow up to [38065] to ensure that `wp.html.string()` always
converts empty `alt` attributes to `alt=""` rather than returning HTML using
empty attribute notation, like `alt`. This allows screen readers to ignore
images with empty `alt` attributes, rather than reading out the URL string.

Additionally this completely removes the logic in `wp.html.string()` for
converting blank attributes to empty attribute notation since empty attribute
notation is generally meant to denote a boolean value, e.g.,
`checked` == `checked="checked"`, which doesn't apply in this context because
boolean attributes must be omitted in order to represent a `false` value.
See: https://www.w3.org/TR/html5/infrastructure.html#boolean-attributes

1736b7b29c Media: Clean up prior image edits if IMAGE_EDIT_OVERWRITE is true.
When `IMAGE_EDIT_OVERWRITE` is set to true, edited image files are
supposed to be deleted when an image is restored to the original.

However, when an image was edited more than once, and then restored,
files created during previous edits were left behind.

Fixes this behavior by updating `wp_save_image()` to clean up
leftover images after each edit when `IMAGE_EDIT_OVERWRITE` is true.

01b9ca2292 Taxonomy: Improve back compat of values passed to 'terms_clauses' filter.
Prior to the introduction of `WP_Term_Query`, the 'orderby' clause
passed to the 'terms_clauses' filter was prefixed by `ORDER BY`. After
`WP_Term_Query`, this was not the case; `ORDER BY` was added after the
filter. As such, plugins filtering 'terms_clauses' and returning an
'orderby' clause beginning with `ORDER BY` resulted in invalid syntax
when `WP_Term_Query` prepended a second `ORDER BY` keyword to
the clause.

This changeset rearranges the way the 'orderby' clause is built so that
it will be passed to 'terms_clauses' in the previous format.

30851d1186 Meta: Remove object subtype handling from register_meta().
Registration is now based solely on object type, which allows the code around this to be simplified significantly.

In the process of making this adjustment:

* `register_meta()`, `unregister_meta_key()`, `get_registered_metadata()`, and `registered_meta_key_exists()` no longer return `WP_Error` objects.
* The recently introduced `wp_object_type_exists()` function and the restriction on object type has been removed.

Note: No guarantee of uniqueness is made across object subtypes. Registered meta keys should be uniquely prefixed to avoid conflict.

Fixes #35658.

a320320ea0 Plugins: Use the correct admin screen when searching for plugins via Ajax.
Both list tables provide different actions based on where they are loaded, regular admin or network admin. Since there is only one Ajax handler for both screens we have to set the current screen before using the list tables.
