Prior to this change, resuming or activating a plugin or theme that is still broken would result in a redirect loop if in recovery mode. If outside recovery mode, it would cause the error template to be displayed.
Furthermore this applies to breaking a plugin or theme when editing from the backend.

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.

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.

Because WP REST API requests aren't identified until `parse_request`, it's impractical to reference the `REST_REQUEST` constant in `wp_debug_mode()`. Instead, it's more helpful to assume that a request wanting a JSON response probably doesn't want PHP errors breaking the response.

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.

A new global multisite table `wp_blogmeta` is added to the database schema, and a set of `*_site_meta()` API functions are introduced.
The implementation fails gracefully when the new table is not yet available, which may happen especially shortly after the core update, before the network has been upgraded to the new database schema. The presence of the table is detected once and stored as a global setting on the main network.
Core does not yet use site metadata, but there are several use-cases to be implemented or explored in the near future, and it allows plugins to extend sites with arbitrary data, which will come in particularly handy with the upcoming REST API endpoint for sites.

Rework logic for how external object caches are detected, so that if
an external cache does not define a `wp_cache_init()`, the built-in
object cache will be used.
Object caches can now wrap their entire contents in logic checks. So a
Redis caching backend could make sure that the `Redis` PHP class is
available before defining all the caching functions. And if Redis is
not available, the site doesn't break or throw errors or think it is
using caching when it isn't. This is particularly useful for doing
local development, where you might want to develop on a site without
running Memcache or Redis like you are in production.
* Accounts for multisite, which may re-initialize the object cache
multiple times.
* Accounts for object caches that may include `object-cache.php` during
`advanced-cache.php` (before WP loads it).

* Edits to active plugins which cause PHP fatal errors will no longer auto-deactivate the plugin. Supersedes #39766.
* Introduce sandboxed PHP file edits for active themes, preventing accidental whitescreening of a user's site when introducing a fatal error.
* After writing a change to a PHP file for an active theme or plugin, perform loopback requests on the file editor admin screens and the homepage to check for fatal errors. If a fatal error is encountered, roll back the edited file and display the error to the user to fix and try again.
* Introduce a secure way to scrape PHP fatal errors from a site via `wp_start_scraping_edited_file_errors()` and `wp_finalize_scraping_edited_file_errors()`.
* Moves file modifications from `theme-editor.php` and `plugin-editor.php` to common `wp_edit_theme_plugin_file()` function.

* Use `get` method for theme/plugin dropdowns.
* Improve styling of plugin editors, including width of plugin/theme dropdowns.

* Strip common base directory from plugin file list. See #24048.

* Scroll to line in editor that has linting error when attempting to save. See #41886.

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).

Previously we ensured that the entry points to WordPress were parsable by PHP4 in order to display a friendly not-supported-php error message.
However, for the last two years the main entry points have not actually parsed, and we've only added extra parse errors since it last worked in 3.9, so it's time we just remove this 'feature'.
The PHP version checks are still there for PHP 5.0/5.1, and so it's inplace when we eventually drop PHP 5.2 support.
