desrosj 27485fd7aa General: Continuing to work towards a passing PHP Compatibility scan.
This is a final pass to fix PHP compatibiilty issues in the codebase with code changes or adding `phpcs:ignore` comments.

With this change, all PHP compatibility warnings and errors without specific tickets have been addressed (see #49810 and #41750).

Sergey Biryukov 46951e0b17 Posts, Post Types: Fail gracefully when checking mapped cap against unregistered post status.
With `map_meta_cap` enabled for a post type, the `read_post` capability for posts with a public status is supposed to be mapped to the post type's `read` capability.

When a post is left in the database after the post status is no longer present, and WP does a `read_post` check against it, a PHP notice was thrown, and the cap check always failed.

As a more graceful fallback, the cap is now mapped onto `edit_others_posts`, which allows highly privileged users to be able to access orphaned content.

A `_doing_it_wrong()` notice is also added, so that developers and site administrators are aware that the cap mapping is failing in the absence of the registered post status.

Follow-up to [34091], which introduced a similar approach to checking mapped caps against an unregistered post type.

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 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 `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.

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.

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.

Felix Arntz 021afced82 Role/Capability: Prevent a fatal error when checking a language capability early or in the frontend.
The meta capabilities `install_languages` and `update_languages` rely on the admin function `wp_can_install_language_pack()`. That function in turn relies on `request_filesystem_credentials()`, so it needs to be ensured that this function is available as well.

Fixes #42230.

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.

Felix Arntz f6ebc1a80c Role/Capability: Introduce capabilities dedicated to installing and updating language files.
The new meta capabilities are called `install_languages` and `update_languages`. Prior to this change, there were no proper capability checks applied. Instead only the filesystem and related constants were checked, and for actual permissions a rather vague fallback was used where a user needed to have at least one of the other updating capabilities. In addition to being generally more verbose, the new capabilities make it possible for example to allow a user to update languages, but nothing else. By default they fall back to the original way of how they were handled.

Boone Gorges fa2f4b047a Avoid PHP notices when checking termmeta capabilities against a non-existent term.
Previously, checks like `current_user_can( 'edit_term_meta', $term_id )`
returned the proper value, but generated a PHP notice due to the fact
that `get_term( $term_id )` could, in certain instances, return
`WP_Error` objects.

Felix Arntz 9354ea683f Multisite: Introduce an `upgrade_network` capability.
Prior to this change, a mix of `is_super_admin()` calls and `manage_network` capability checks was used to determine whether the current user could upgrade the network. With this changeset a dedicated capability is introduced that allows more granular handling.

Felix Arntz 00e8704288 Multisite: Introduce a `setup_network` capability for setting up multisite.
`setup_network` is a new meta capability that brings more granular control over the permissions to setup a multisite environment. In a non-multisite environment it falls back to `manage_options` while in a multisite it falls back to `manage_network_options`. The introduction of this capability furthermore allows replacing an `is_super_admin()` check.

Felix Arntz f704fc808a Multisite: Handle capability check for removing oneself via `map_meta_cap()`.
Site administrators should not be able to remove themselves from a site. This moves the enforcement of this rule from `wp-admin/users.php` to `remove_user_from_blog()` via the `remove_user` capability, which furthermore allows us to get rid of two additional clauses and their `is_super_admin()` checks in `wp-admin/users.php`. A unit test for the new behavior has been added.
