Gary Pendergast 5d658427a8 Code Modernisation: Introduce the spread operator in `capabilities.php`.
Rather than relying `func_get_args()` to retrieve arbitrary function arguments, we can now use the spread operator to assign them directly to a variable.

Props jrf.

Peter Wilson a5e57d7245 Site health: Introduce `view_site_health_checks` capability.
Introduces the faux primitive capability `view_site_health_checks` available to single site admins and multisite super-admin to view the site health page within the admin.

The capability is mapped to the `install_plugins` capability without being dependent on the file system being writable. This fixes a bug where the feature couldn't be used by sites unable to write to the file system or managed through version control.

The capability is granted on the `user_has_cap` filter.

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.

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.

Introduce an `object_subtype` argument to the args array for `register_meta()` which can be used to limit meta registration to a single subtype (e.g. a custom post type or taxonomy, vs all posts or taxonomies).

Introduce `register_post_meta()` and `register_term_meta()` wrapper methods for `register_meta` to provide a convenient interface for the common case of registering meta for a specific taxonomy or post type. These methods work the way plugin developers have often expected `register_meta` to function, and should be used in place of direct `register_meta` where possible.

iandunn 461d17576c Privacy: Require `manage_privacy_options` to edit policy page.
A user is required to have the `manage_privacy_options` capability in order to determine which page is set as the privacy policy (the `wp_page_for_privacy_policy`). Given that, it doesn't make sense to allow users without that capability to edit or delete the page. 

A similar situation exists with the `page_for_posts` and `page_on_front` options, but Editors are allowed to edit those pages. The reason that this situation is different is because it is more likely that an administrator will want to restrict modifications to the privacy policy, than it is that they will want to allow modifications. Modifications to the policy often require specialized knowledge of local laws, and can have implications for compliance with those laws.

iandunn 9faae413dc Privacy: Limit Privacy Settings screen to Super Admins in Multisite.
In many common Multisite use cases, the network administrator will want to set a network-wide privacy policy -- via the `privacy_policy_url` filter -- for consistency and convenience. When that's done, the Privacy Settings screen on individual sites becomes unnecessary, and may confuse administrators of those sites when they see that their changes don't have any effect on the policy link in the footer.

Since we can't programatically determine which behavior the network admins would like, the safest default setting is to restrict the ability to super admins, and let them delegate it to individual site owners via a plugin, if they'd like to.

iandunn 93a90a9aa4 Privacy: Limit export and erasure to super admins on Multisite.
Multisite networks have a variety of use cases, and in many of them single-site administrators are not trusted to take actions that affect the whole network, require making decisions about legal compliance, etc. By default, those actions should require super admin capabilities. Plugins can be used to override that behavior if a particular site's use case calls for it.

Felix Arntz ed1df81bba General: Introduce dashboard widget to inform administrators about outdated PHP versions.
This new dashboard widget is shown on WordPress sites which are powered by a PHP version which WordPress considers outdated, in order to inform site owners about the resulting problems and to explain how to upgrade to a supported version. An education page for that purpose has been previously created that the widget links to. The link is translatable so that localized versions of the page can be referred to as they become available.

The nag follows the example of the Browse Happy dashboard widget and is only visible for administrators, or network administrators when using multisite. To determine whether it needs to be displayed, a new wordpress.org API introduced prior is called that handles the version logic in a centralized location.

John Blackbourn c7a79b0e6a Plugins: Introduce singular capabilities for activating and deactivating individual plugins.
This introduces the following meta capabilities:

* `activate_plugin`
* `deactivate_plugin`
* `deactivate_plugins`

The singular `activate_plugin` and `deactivate_plugin` capabilities are used along with the corresponding plugin name when
determining whether or not a user can activate or deactivate an individual plugin.

The plural `deactivate_plugins` capability is used in place of the existing `activate_plugins` capability when determining
whether a user can deactivate plugins.

Each of these new meta capabilities map to the existing `activate_plugins` primitive capability, which means there is no
change in existing behaviour, but plugins can now filter the capabilities required to activate and deactivate individual
plugins.

Weston Ruter 1ccd9e7a6c Customize: Introduce custom CSS for extending theme styles.
* 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.

John Blackbourn b84023ea33 Taxonomy: Introduce more fine grained capabilities for managing taxonomy terms.
This introduces the singular `edit_term`, `delete_term`, and `assign_term` meta capabilities for terms, and switches the base capability name for tags from `manage_categories` to `manage_post_tags` and the corresponding `edit_post_tags`, `delete_post_tags`, and `assign_post_tags`.

All of these capabilities ultimately map to `manage_categories` so by default there is no change in the behaviour of the capabilities for categories, tags, or custom taxonomies. The `map_meta_cap` filter and the `capabilities` argument when registering a taxonomy now allow for control over editing, deleting, and assigning individual terms, as well as a separation of capabilities for tags from those of categories.

Helen Hou-Sandí 69ccab3405 Introduce an expanded meta registration API.
`register_meta()` has been altered to accept an array of arguments as the third parameter in order to support its usage beyond XML-RPC, notably in the REST API and other projects that may build on top of meta, such as a potential Fields API. Arguments are whitelisted to reserve the right for core to add more later.

New functions added to complement this expansion are:
* `registered_meta_key_exists()`
* `unregister_meta_key()`
* `get_registered_meta_keys()`
* `get_registered_metadata()`
* A "private" function for the aforementioned whitelisting.

There still need to be lots of tests written for previous and new behaviors, and many things are subject to change. Maybe things will explode. #yolo

Drew Jaynes fe3b007fdd Docs: Remove inline `@see` tags from function, class, and method references in inline docs.
Known functions, classes, and methods are now auto-linked in Code Reference pages following #meta1483.

Note: Hook references are still linked via inline `@see` tags due to the unlikelihood of reliably matching for known hooks based on a RegEx pattern.

Jeremy Felt 6cc19b5e2e Multisite: Relocate `revoke_super_admin()` and `grant_super_admin()`
Moving these functions to `wp-includes/capabilities.php` allows plugins to access more than just `is_super_admin()` and `get_super_admin()` from the front end without including a file via `wp-admin/`. Add an `is_multisite()` check to prevent use of these on single site environments now that they have left `ms.php`..

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.
