Improve performance of Emoji tests and loading of the polyfill.
Reduces the number of tests to determine browser support for emoji to those most likely to fail. Adds the defer flag to the loaded scripts for browsers lacking support.
Props superpoincare for perf testing, peterwilsoncc.

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!"

* Custom CSS is associated with a given theme and is displayed in an inline `style` element at the `wp_head` hook after the `wp_print_styles` is called so that it overrides any enqueued stylesheets.
* A `wp_get_custom_css()` function is used for accessing the CSS associated with the current theme (or another theme) and a `wp_get_custom_css` filter for manipulating it.
* CSS is managed in customizer via a new "Additional CSS" section with a single `textarea` control.
* `WP_Customize_Section::$description_hidden` is introduced for hiding extended descriptions in customizer sections behind a help toggle as done with panels.
* CSS is stored in a `custom_css` post type with the theme (stylesheet) slug as the `post_name`.
* `WP_Customize_Custom_CSS_Setting` is introduced to handle validation of CSS, previewing, and persisting the CSS to the `custom_css` post type.
* The `custom_css` setting is tied to a new `unfiltered_css` capability which maps to `unfiltered_html` by default.
* Escaping the message in the notification template is removed to allow markup (`code` tags) to be rendered.

This removes the fallbacks in `wp_get_attachment_image()` and in
`wp.media.string.props` which attempt to generate an `alt` value
from the image caption or title if an `alt` attribute isn't explicitly
set.
This allows for image HTML to be generated that contains an empty `alt`
value, i.e., `alt=""` which is much preferable for screen readers than
reading redundant content in the case of a caption, or when reading the
image title, which is often generated from the filename and not helpful
as `alt` text.

The Customizer and Theme Installer open in full overlays that need to receive
focus. Also, keyboard navigation should be constrained within the overlays. Using
CSS `visibility` to hide all the content except the overlays, makes them the only
available and focusable content and allows browsers to handle focus natively.

* Eliminates the server mutating the a `WP_Error`'s `$error_data` to merge-in a `$from_server` flag (since it may not be an array to begin with). Instead it defers to the client to add a `fromServer` param on any `Notification` instances created from server-sent errors.
* Ensures that notifications will be re-rendered if a notification's `message` changes but the `data` and `type` remain the same.
* Adds explicit support for the `Notification` class to have a `setting` property, ensuring that the property is set whereas previously it was dropped.

WordPress maintains the minified version of jquery.masonry.js since there is no official build, however it has been excluded from grunt's minification process. This adds a minification task to grunt, adds it to the precommit hook for JS, minifies the file, and bumps the version on jquery.masonry.min.js. The change to the non minified version was introduced in [38261].

[38179] added support for the rainbow flag to core, but platform compatibility is a bit strange, because the flag was defined out of sync with the usual Unicode release cycle. For example Android N supports all Unicode 9.0 emoji, but doesn't support the rainbow flag thus the rainbow flag isn't rendered.
The Twemoji loader already has an exception for flags - it'll load if the browser supports everything but flags, and then only replace flag emoji, leaving everything else as native rendering. To provide a seamless experience for all flags the loader now uses the rainbow flag to test flag support.
Props pento.

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.

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.
