Felix Arntz 3a77265148 Bootstrap/Load: Introduce a recovery mode for fixing fatal errors.
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.

Felix Arntz 92c3c46abe Bootstrap/Load: Revert fatal error recovery mechanism from 5.1 to polish for 5.2.
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.

Fixes #46141. See #44458, #45932, #45940, #46038, #46047, #46068.

Felix Arntz 1e4088fc98 Bootstrap/Load: Introduce fatal error recovery mechanism allowing users to still log in to their admin dashboard.
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.

Gary Pendergast 56c162fbc9 Coding Standards: Upgrade WPCS to 1.0.0
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.

Fixes #44600.

Dion Hulse 28677d382d Theme/Plugin Editor: Remove the caching added in [41806] as it causes more problems than it fixes.
While caching here seemed like a good idea in theory, in practice the cache would be often stale causing development issues.
We exclude common folders (such as `node_modules`) from the scanning to avoid directories which are not useful to the end-user, so as long as those exclusion lists are held up this shouldn't cause too much of a degredation in the future.
We may consider adding caching here again in the future if it's determined that it is really needed.

Drew Jaynes 0860bb2771 Docs: Remove `@access` notations from method DocBlocks in wp-includes/* classes.
Prior to about 2013, many class methods lacked even access modifiers which made the `@access` notations that much more useful. Now that we've gotten to a point where the codebase is more mature from a maintenance perspective and we can finally remove these notations. Notable exceptions to this change include standalone functions notated as private as well as some classes still considered to represent "private" APIs.

Pascal Birchler 81a26f6900 Posts, Post Types: Add support for post type templates.
WordPress has supported custom page templates for over 12 years, allowing developers to create various layouts for specific pages.
While this feature is very helpful, it has always been limited to the 'page' post type and not was not available to other post types.

By opening up the page template functionality to all post types, we continue to improve the template hierarchy's flexibility.

In addition to the `Template Name` file header, the post types supported by a template can be specified using `Template Post Type: post, foo, bar`.
When at least one template exists for a post type, the 'Post Attributes' meta box will be displayed in the back end, without the need to add post type support for `'page-attributes'`. 'Post Attributes' can be customized per post type using the `'attributes'` label when registering a post type.

Eric Lewis 22467e840f Networks and sites: Replace "blog" usage with "site" in docs.
Multisite functions use the term "blog" to refer to what we now call a "site," e.g. `get_current_blog_id()`. These functions are here to stay because of our commitment to backwards compatibility. What we can do is set the documentation straight.

See #35417.

Jeremy Felt 3018d9827c Themes: Enhance filtering options for allowed themes on a network.
* Move the legacy `allowed_themes` filter to `WP_Theme::get_allowed_on_network()`, where it will continue to filter themes allowed on the network.
* Add `network_allowed_themes` filter to `WP_Theme::get_allowed()` and pass `$blog_id` to provide context.
* Add `site_allowed_themes` filter to `WP_Theme::get_allowed_on_site()` and pass `$blog_id` to provide context.

Scott Taylor 79a2915a9b Upgrade: New themes are not automatically installed on upgrade. This can still be explicitly asked for by defining `CORE_UPGRADE_SKIP_NEW_BUNDLED` as `false`.
In `populate_options()`, if the theme specified by `WP_DEFAULT_THEME` doesn't exist, fall back to the latest core default theme. If we can't find a core default theme, `WP_DEFAULT_THEME` is the best we can do. 

Props nacin, jeremyfelt, dd32.
