Using the new fatal handler introduced in [44962], an email is sent to the admin when a fatal error occurs. This email includes a secret link to enter recovery mode. When clicked, the link will be validated and on success a cookie will be placed on the client, enabling recovery mode for that user. This functionality is executed early before plugins and themes are loaded, in order to be unaffected by potential fatal errors these might be causing.
When in recovery mode, broken plugins and themes will be paused for that client, so that they are able to access the admin backend despite of these errors. They are notified about the broken extensions and the errors caused, and can then decide whether they would like to temporarily deactivate the extension or fix the problem and resume the extension.
A link in the admin bar allows the client to exit recovery mode.

Due to the high number of follow-up tickets and associated security concerns, it was decided to reschedule the fatal error recovery feature for WordPress 5.2, in order to address these issues properly. The feature will continue to be developed, with iterations being merged into trunk early in the 5.2 release cycle.

This changeset introduces a `WP_Shutdown_Handler` class that detects fatal errors and which extension (plugin or theme) causes them. Such an error is then recorded, and an error message is displayed. Subsequently, in certain protected areas, for example the admin, the broken extension will be paused, ensuring that the website is still usable in the respective area. The major benefit is that this mechanism allows site owners to still log in to their website, to fix the problem by either disabling the extension or solving the bug and then resuming the extension.
Extensions are only paused in certain designated areas. The frontend for example stays unaffected, as it is impossible to know what pausing the extension would cause to be missing, so it might be preferrable to clearly see that the website is temporarily not accessible instead.
The fatal error recovery is especially important in scope of encouraging the switch to a maintained PHP version, as not necessarily every WordPress extension is compatible with all PHP versions. If problems occur now, non-technical site owners that do not have immediate access to the codebase are not locked out of their site and can at least temporarily solve the problem quickly.
Websites that have custom requirements in that regard can implement their own shutdown handler by adding a `shutdown-handler.php` drop-in that returns the handler instance to use, which must be based on a class that inherits `WP_Shutdown_Handler`. That handler will then be used in place of the default one.
Websites that would like to modify specifically the error template displayed in the frontend can add a `php-error.php` drop-in that works similarly to the existing `db-error.php` drop-in.

WPCS 1.0.0 includes a bunch of new auto-fixers, which drops the number of coding standards issues across WordPress significantly. Prior to running the auto-fixers, there were 15,312 issues detected. With this commit, we now drop to 4,769 issues.
This change includes three notable additions:
- Multiline function calls must now put each parameter on a new line.
- Auto-formatting files is now part of the `grunt precommit` script.
- Auto-fixable coding standards issues will now cause Travis failures.

This pattern occurs a handful of times across the codebase:
`<div class="foo<?php if ( $bar ) { echo ' baz'; } ?>">`
Unfortunately, it doesn't really play nicely with `phpcbf`, so all instances need to be removed in preperation for auto code formatting.

* Remove customizer-loader from being used on admin screens for Dashboard, Themes, non-shiny theme install/update.
* Keep the customize-loader functionality available for plugins, for the time being. It may become deprecated.
* Ensure `return` param in customizer links in Themes screen update to reflect `search` updated by `pushState`.
* Persist `return` when reloading Customizer due to theme switch, autosave restoration, or changeset trashing.
* Use `location.replace()` instead of changing `location.href` when trashing.
* Hide theme browser while Themes screen is loading when there is a `search` to prevent flash of unfiltered themes.
* Use throttling instead of debouncing when searching themes to ensure that screen is updated immediately on page load.
* Fix encoding and decoding of `search` param between URL and search field.
* Add support for dismissing autosaves when closing customize-loader, when it is used by plugins.
* Skip sending changeset UUID to customize-loader for population in browser location if changeset branching is not enabled.

Valid code is important not just to formally meet the specification, but also to
ensure user agents, including assistive technologies, can accurately interpret
and parse content. When HTML elements are not used in the recommended way,
user agents may render them in unexpected ways. It can also become a problem for
compatibility with older or even future browsers, devices, or other software.

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

These no longer return upon refreshing the page when JS is on and working, so users should be able to dismiss them.

JavaScript is rarely disabled, but graceful degradation is still important. For example, syntax errors can occur, usually with major WP updates that overhaul entire experiences and update external libraries combined with themes or plugins doing weird or old things. If this error is due to their current theme, a user needs to be able to access the themes screen to switch away from the theme. A more subtle issue could make things painful to diagnose.
This commit renders the grid in PHP (the template is duplicated, but it lightweight, fairly mundane, and easy to sync). On Backbone render, the grid is then re-rendered from JavaScript so searches can occur. Customize and Live Preview is disabled if JS fails to kick in. If JS is disabled, old-school "Preview" links are displayed.
No-Customizer support: The customizer is only supported when the browser supports postMessage (IE8+), and if the frontend is a different domain, CORS (IE10+). We use the .hide-if-no-customize class for this. Pre-customize "Preview" links should use .hide-if-customize.
The .load-customize class should be used to declare a link that opens the customizer. This enables customize-loader.js to intercept this link and load the customizer on top of the current window, making for a smoother experience.
