To mirror theme list table behaviour, the plugin icon now appears next to plugins in the plugin list tables. For plugins that don't have an icon, or non-W.org plugins, a fallback dashicon is shown.

`get_current_blog_id()` is more appropriate for determining the ID of the current site in most cases. This eliminates the need for the global `$wpdb` in several functions and is better than the implicit global used in admin pages.

Unify the theme-browsing and theme-customization experiences by introducing a comprehensive theme browser and installer directly accessible in the customizer. Replaces the customizer theme switcher with a full-screen panel for discovering/browsing and installing themes available on WordPress.org. Themes can now be installed and previewed directly in the customizer without entering the wp-admin context. Also includes an extensible framework for browsing and installing themes from other sources.
Also includes CSS auto-prefixing added via `grunt precommit:css`.

- uses `aria-expanded` on the toggles to communicate to assistive technologies the panels expanded/collapsed state
- adds the "circular focus" style to the toggles to give users a clear indication of the currently focused element
- standardizes CSS class names to `.toggle-indicator` and `.handlediv` as these names are already used across the admin for similar controls

Calling the `count_users()` function is expensive, regardless of the counting strategy that's used, and it gets
slower the more users there are on a site. In order to speed up the Users screen in the admin area, calling
`count_users()` can be avoided entirely while still displaying the total count for users.
This introduces some new functions:
* `wp_is_large_user_count()`
* `wp_get_active_user_count()`
* `wp_update_active_user_count()`
A corresponding `wp_is_large_user_count` filter is also introduced.

* Invalidate PHP opcache after file is updated to ensure `include` will ''include'' the written changes.
* Define `WP_ADMIN` when activating plugin in sandbox so plugin code targeting admin will be loaded.
* Do actions that get triggered when loading the admin to ensure plugin code runs that could cause errors on plugin editor screen (and lock out access).
* Fix ability to re-activate a plugin after editing a PHP file other than the main plugin file, and ensure PHP fatal error will be displayed in such cases.
* Consolidate duplicated code into `plugin_sandbox_scrape()` and re-use in `activate_plugin()`.
* Show an error notice instead of a success notice when a file is updated but a plugin was deactivated due to a fatal error.
* Update style of warning when editing an active plugin to be styled as an actual warning notice.

* Code editor is integrated into the Theme/Plugin Editor, Additional CSS in Customizer, and Custom HTML widget. Code editor is not yet integrated into the post editor, and it may not be until accessibility concerns are addressed.
* The CodeMirror component in the Custom HTML widget is integrated in a similar way to TinyMCE being integrated into the Text widget, adopting the same approach for integrating dynamic JavaScript-initialized fields.
* Linting is performed for JS, CSS, HTML, and JSON via JSHint, CSSLint, HTMLHint, and JSONLint respectively. Linting is not yet supported for PHP.
* When user lacks `unfiltered_html` the capability, the Custom HTML widget will report any Kses-invalid elements and attributes as errors via a custom Kses rule for HTMLHint.
* When linting errors are detected, the user will be prevented from saving the code until the errors are fixed, reducing instances of broken websites.
* The placeholder value is removed from Custom CSS in favor of a fleshed-out section description which now auto-expands when the CSS field is empty. See #39892.
* The CodeMirror library is included as `wp.CodeMirror` to prevent conflicts with any existing `CodeMirror` global.
* An `wp.codeEditor.initialize()` API in JS is provided to convert a `textarea` into CodeMirror, with a `wp_enqueue_code_editor()` function in PHP to manage enqueueing the assets and settings needed to edit a given type of code.
* A user preference is added to manage whether or not "syntax highlighting" is enabled. The feature is opt-out, being enabled by default.
* Allowed file extensions in the theme and plugin editors have been updated to include formats which CodeMirror has modes for: `conf`, `css`, `diff`, `patch`, `html`, `htm`, `http`, `js`, `json`, `jsx`, `less`, `md`, `php`, `phtml`, `php3`, `php4`, `php5`, `php7`, `phps`, `scss`, `sass`, `sh`, `bash`, `sql`, `svg`, `xml`, `yml`, `yaml`, `txt`.

* Mark a widget as dirty when a field input triggers a `change` or `input` event; clear dirty state when widget is successfully saved.
* Disable Save button and re-label "Saved" when widget not dirty.
* Show AYS dialog when leaving widgets admin screen with unsaved changes.
* When widgets are dirty, expand all unsaved widgets at AYS check and focus on first one.
* Change "Close" link to "Done"; hide link when widget is dirty and reveal when saved.
* The "Done" link persistently appears in the Customizer even after making a change (when the widget is dirty) because changes are autosaved into the changeset.
* Prevent saving widget when form fails `checkValidity`.
* Fix frequency of triggering of `change` event on the rich Text widget's `textarea` limited now to when there are actual changes.
* Add a class of `widget-dirty` to widget containers when the widget has unsaved changes.

This fixes an issue where failures when inserting the attachment post via
`wp_insert_attachment()` would result in a return value of `0` instead of a
`WP_Error` object, as documented. This is addressed by passing `true` as the

These log entries are only useful when troubleshooting unexpected results from the API, which is not common. The vast majority of users are better served by not having their logs cluttered with noise.
For the rare situations where troubleshooting is necessary, it can be achieved by a plugin (see #41217 for an example).

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.
