7e29c9646a Customizer: Minimize duplicate header crops in the media library.
This adds `Custom_Image_Header::get_previous_crop()`, which finds any
previously cropped headers created from the same base image and replaces
that attachment rather than creating a new attachment.

After updating a crop, the replaced images is also removed from the list
of previous header images in the Customizer.

See #21819.

f8c6040ff5 Customize: Improve usability of Customize JS API.
* Eliminate need to pass both ID and instance in calls to `Values#add()` for panels, sections, controls, settings, partials, and notifications.
* Eliminate need to supply `content` param when constructing a `Control`.
* Unwrap the `options.params` object passed in constructors to just pass a flat `options`. (Back-compat is maintained.)
* Add support for `templateId` param for `Control` to override which template is used for the content.
* Remove unused `previewer` being supplied in `Control` instances.
* Rename `classes` to `containerClasses` on `Notification`.
* Automatically supply `instanceNumber` to improve stable sorting.
* Use `api.Notifications` for notifications in settings instead of `api.Value`.

5f7a5c1246 File Editors: Introduce sandboxed live editing of PHP files with rollbacks for both themes and plugins.
* 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.
* Refactor themes and plugin editors to submit file changes via Ajax instead of doing full page refreshes when JS is available.
* Use `get` method for theme/plugin dropdowns.
* Improve styling of plugin editors, including width of plugin/theme dropdowns.
* Improve notices API for theme/plugin editor JS component.
* Strip common base directory from plugin file list. See #24048.
* Factor out functions to list editable file types in `wp_get_theme_file_editable_extensions()` and `wp_get_plugin_file_editable_extensions()`.
* Scroll to line in editor that has linting error when attempting to save. See #41886.
* Add checkbox to dismiss lint errors to proceed with saving. See #41887.
* Only style the Update File button as disabled instead of actually disabling it for accessibility reasons.
* Ensure that value from CodeMirror is used instead of `textarea` when CodeMirror is present.
* Add "Are you sure?" check when leaving editor when there are unsaved changes.

728e44ab5a Customize: Add infrastructure for trashing/reverting of unpublished changes; introduce full-screen OverlayNotification for trashing and theme install/preview.
* Introduce a new `wp.customize.previewer.trash()` JS API to trash the current changeset, along with logic to `WP_Customize_Manager` to handle deleting changeset drafts.
* Add `trashing` to `wp.customize.state` which is then used to update the UI.
* UI for trashing is pending design feedback. One possibility is to add a new trash button to Publish Settings section that invokes `wp.customize.previewer.trash()`.
* Improve logic for managing the visibility and disabled states for publish buttons.
* Prevent attempting `requestChangesetUpdate` while processing and bump processing while doing `save`.
* Update `changeset_date` state only if sent in save response.
* Merge `ThemesSection#loadThemePreview()` into `ThemesPanel#loadThemePreview()`.
* Remove unused `autosaved` state.
* Start autosaving and prompting at beforeunload after a change first happens. This is key for theme previews since even if a user did not make any changes, there were still dirty settings which would get stored in an auto-draft unexpectedly.
* Allow `Notification` to accept additional `classes` to be added to `container`.
* Introduce `OverlayNotification` and use for theme installing, previewing, and trashing. Such overlay notifications take over the entire window.

Unify the theme-browsing and theme-customization experiences by introducing a comprehensive theme browser and installer directly accessible in the customizer.

8043c2d8e5 Customize: Introduce drafting and scheduling for Customizer changesets.
* Incorporates code from the Customize Snapshots and Customize Posts feature plugins.
* Adds a new Publish Settings section for managing the changeset status, scheduled date, and frontend preview link.
* Updates Publish button to reflect the status selected in the Publish Settings (including Save Draft and Schedule).
* Deactivates the Themes section when a non-publish status selected, and deactivates the Publish Settings section when previewing a theme switch.
* Introduces an `outer` section type (`wp.customize.OuterSection` in JS) for the Publish Settings section to use and for available widgets and available nav menu panels to use in the future. These sections can be expanded while other sections are expanded.
* Introduces `WP_Customize_Date_Time_Control` in PHP and `wp.customize.DateTimeControl` in JS for managing a date/time value.
* Keeps track of scheduled time and proactively publish from the client when the time arrives, as opposed to waiting for WP Cron.
* Auto-publishes a scheduled changeset when attempting to access one that missed its schedule.
* Starts a new changeset if attempting to save a changeset that was previously publish.
* Adds `force` arg to `requestChangesetUpdate()` to force an update request even when there are no pending changes.
* Adds utils methods for `getCurrentTimestamp` and `getRemainingTime`.
* Adds new state values for `selectedChangesetStatus`, `changesetDate`, `selectedChangesetDate`.
* Fixes logic for when to short-circuit check to close Customizer when there are unsaved changes.
* Adds getter methods for `autosaved` and `branching` parameters, with the latter applying the `customize_changeset_branching` filter.
* Call to `establish_loaded_changeset` on the fly when `changeset_uuid()` is called if no changeset UUID was specififed.
* De-duplicates logic for dismissing auto-draft changesets.
* Includes unit tests.

c65fe27ba1 Accessibility: Update and standardize the admin screen-reader-text CSS class.
Given the new WordPress browsers support policy, the `screen-reader-text` css
class used in the admin can be updated to use modern CSS and correct syntax. See
https://github.com/wpaccessibility/a11ythemepatterns/blob/master/read-more-links/style.css

Worth noting the `clip` property is deprecated and kept for IE11 and Edge.

- uses `clip-path` for modern browsers
- keeps `clip` for old browsers and update its value to a correct syntax
- resets `clip-path` to `none` where the class is used to dynamically reveal elements
- removes an old rule that made `screen-reader-text` completely invisible in the help tabs `#screen-meta`
- standardizes the rule across CSS files

807bc5a6c9 Users: Introduce the concept of a large site in order to speed up the Users screen when there are many users.
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.

1a7616ad54 Customize: Extend changesets to support autosave revisions with restoration notifications, and introduce a new default linear history mode for saved changesets (with a filter for opt-in to changeset branching).
* Autosaved changes made on top of `auto-draft` changesets get written on top of the `auto-draft` itself, similar to how autosaves for posts will overwrite post drafts.
* Autosaved changes made to saved changesets (e.g. `draft`, `future`) will be placed into an autosave revision for that changeset and that user.
* Opening the Customizer will now prompt the user to restore their most recent auto-draft changeset; if notification is dismissed or ignored then the auto-draft will be marked as dismissed and will not be prompted to user in a notification again.
* Customizer will no longer automatically supply the `changeset_uuid` param in the `customize.php` URL when branching changesets are not active.
* If user closes Customizer explicitly via clicking on X link, then autosave auto-draft/autosave will be dismissed so as to not be prompted again.
* If there is a changeset already saved as a `draft` or `future` (UI is forthcoming) then this changeset will now be autoloaded for the user to keep making additional changes. This is the linear model for changesets.
* To restore the previous behavior of the Customizer where each session started a new changeset, regardless of whether or not there was an existing changeset saved, there is now a `customize_changeset_branching` hook which can be filtered to return `true`.
* `wp.customize.requestChangesetUpdate()` now supports a second with options including `autosave`, `title`, and `date`.
* The window `blur` event for `customize.php` has been replaced with a `visibilitychange` event to reduce autosave requests when clicking into preview window.
* Adds `autosaved` and `branching` args to `WP_Customize_Manager`.
* The `changeset_uuid` param for `WP_Customize_Manager` is extended to recognize a `false` value which causes the Customizer to defer identifying the UUID until `after_setup_theme` in the new `WP_Customize_Manager::establish_loaded_changeset()` method.
* A new `customize_autosaved` query parameter can now be supplied which is passed into the `autosaved` arg in `WP_Customize_Manager`; this option is an opt-in to source data from the autosave revision, allowing a user to restore autosaved changes.

90bedf8f9d Editor: Add CodeMirror-powered code editor with syntax highlighting, linting, and auto-completion.
* 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`.

d8f445bf0f Customize: Add global notifications area.
* Displays an error notification in the global area when a save attempt is rejected due to invalid settings. An error notification is also displayed when saving fails due to a network error or server error.
* Introduces `wp.customize.Notifications` subclass of `wp.customize.Values` to contain instances of `wp.customize.Notification` and manage their rendering into a container.
* Exposes the global notification area as `wp.customize.notifications` collection instance.
* Updates the `notifications` object on `Control` to use `Notifications` rather than `Values` and to re-use the rendering logic from the former. The old `Control#renderNotifications` method is deprecated.
* Allows notifications to be dismissed by instantiating them with a `dismissible` property.
* Allows `wp.customize.Notification` to be extended with custom templates and `render` functions.
* Triggers a `removed` event on `wp.customize.Values` instances _after_ a value has been removed from the collection.

d35be7a120 Administration: Admin menu: Use aria-current for the current active page.
The `aria-current` attribute is a simple, effective way to communicate to assistive
technologies which the current item within a set of items is. While the admin menu
structure isn't 100% ideal (the top-level item is repeated also as a sub-item)
adding `aria-current="page"` to the sub-items gives an important feedback to
assistive technologies users.

This change introduces `aria-current` for the first time in core. Worth noting
there are other places where it can be used to improve accessibility. These should
be addressed in separate tickets and patches.

a4ae97437b Administration: Thickbox: Fix conflicts with the Plugin details and native Thickbox modals.
The Plugin details modal custom implementation in the Plugins page conflicts with
other Thickbox instances added by plugins. Thickbox shows its age and has been
modified over time to suit core needs. However, WordPress should do its best to
not create conflicts with the native Thickbox styles and functionalities. Plugin
authors should be able to use `add_thickbox()` in any admin page as documented, 
without having to worry about potential errors.

- fixes a JavaScript error when closing a native Thickbox modal in the Plugins page
- avoids to override the native Thickbox modal styles
- uses a CSS class to target the Plugin details modal and remove a pile of overqualified CSS selectors

* 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`.
