An empty string causes some browsers to use the current URL as the `href`. When using `history.replaceState()` Chrome will re-fetch the favicon with each call, meaning that `customize.php` gets hit with wasted requests which tax the server.

One thing fairly common to the cache groups is a block of code to look to see when the cache was last changed, and if there isn't one, to set it for the current microtime(). It appears in 8 different places in core. This adds a new helper `wp_cache_get_last_changed` to DRY things up a bit.
Since `wp-includes/cache.php` isn't guaranteed to be loaded, this new function is in `wp-includes/functions.php`

Introduces some consistency in the usage of the button CSS classes, fixes the
focus style for accessibility and responsiveness of the buttons.
- Adds the `button` class to all primary buttons make them responsive
- Removes all `secondary-button` classes and replaces it with button when needed. `button-secondary` shouldn't be used and exists just for backward compatibility reasons
- Replaces classes inside `submit_button()` with a shorthand for some buttons, and use an empty string for the default `button` class. Passing `button` is unnecessary
- Adjusts `get_submit_button()` to remove empty items

* `wp-admin` and `wp-includes` are scanned for classes to autoload
* Several 3rd-party and Ryan McCue-shaped libraries are excluded when the classmap is generated, see `composer.json`: `autoload.exclude-from-classmap`
* `wp-vendor/autoload_52.php` is included at the top of `wp-settings.php` - no changes need to be made to unit tests to include the autoloader
* An avalanche of `require()` and `require_once()` calls that loaded class files have been removed from the codebase.
The following files have been added to `svn:ignore` - they are not 5.2-compatible and fail during pre-commit:
* src/wp-vendor/autoload.php
* src/wp-vendor/composer/autoload_real.php
* src/wp-vendor/composer/autoload_static.php
* src/wp-vendor/composer/ClassLoader.php
We favor these files instead:
* src/wp-vendor/autoload_52.php
* src/wp-vendor/composer/autoload_real_52.php
* src/wp-vendor/composer/ClassLoader52.php
When new PHP classes are added to the codebase, simply run `composer install` or `composer update` from the project root to update the autoloader.
The future is now.

* `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.

Externally hosted script and style dependencies trigger `dns-prefetch` hinting only when enqueued. This removed a bug in which hinting was added on registration.

Resource hints allow browsers to prefetch specific pages or render them in the background to perform DNS lookups or to begin the connection handshake (DNS, TCP, TLS) in the background.
By default, `wp_resource_hints()` prints hints for "s.w.org" (the WordPress.org CDN) and for all scripts and styles which are enqueued from external hosts.
Use the `wp_resource_hints` filter to add custom domains and URLs for `dns-prefetch`, `preconnect`, `prefetch` or `prerender`.

The return from `wp_logout_url()` is HTML-encoded due to its value passing through `wp_nonce_url()` and thus `esc_html()`. Adversely `wp_login_url()` passes through no such escaping and therefore should not be expected to return an HTML-encoded value.

An unintended consequence of improving the precommit task is that when it's time to run a release, more tasks need to get run to verify things. This adds a prerelease task to help fix that situation. grunt prerelease should include tasks that verify the code base is ready to be released to the wild and find all the tears on the mausoleum floor and help Blood stain the Colosseum doors.

Locales are codes to identify a language in WordPress which can be different from the specification for language tags, see https://www.w3.org/International/articles/language-tags/.
An example is `de_DE_formal` or `nl_NL_formal` where the subtag `formal` isn't officially supported.
To give translators the possibility to specify the language tag of their language introduce a string `html_lang_attribute` which can be translated into the language tag which conforms to the specification.

Splits wp-includes/embed-template.php, introduced in 4.4, into five new templates that can be individually overridden by themes:
* embed.php
* embed-404.php
* embed-content.php
* header-embed.php
* footer-embed.php
Also introduces a new template tag for outputting the site title, `the_embed_site_title()`.
The five new templates live in theme-compat, allowing for graceful fallbacks should themes prefer not to override any or all of them.
