Andrea Fercia d1948f623a Accessibility: CodeMirror editing areas minor improvements.
- properly labels all the code editor areas (Theme/Plugin, Custom HTML widget, Additional CSS), whether CodeMirror is enabled or disabled
- adds `role="textbox"` and `aria-multiline="true"` to the CodeMirror editing area to allow assistive technologies properly identify it as a textarea
- standardizes the "keyboard trap" help text across the admin and keeps it as a list for better readability
- use the Help text elements as target for `aria-describedby`, to make screen readers read out the help text when focusing the editors
- fixes the `aria-expanded` attribute usage in the Customizer "Additional CSS" help toggle
- moves focus to the CodeMirror editing area when clicking on the associated label
- in the Plugin editor screen: changes a `<big>` element to `<h2>` for better semantics and consistency with the Theme editor screen
- also, removes a few textdomain leftovers, see `better-code-editing` and `default`

Props westonruter, melchoyce, afercia.

Weston Ruter f0b5c39bde Customize: Introduce extensible code editor Customizer control for CodeMirror.
* Adds `WP_Customize_Code_Editor_Control` and `wp.customize.CodeEditorControl()`.
* Control respects user preference for syntax highlighting, showing a textarea when user opts out.
* Code editor control takes the ad hoc code for Additional CSS and makes it reusable and extensible, for Additional CSS in core and plugins to use (such as Jetpack).
* Replace `settings` arg in `wp_enqueue_code_editor()` with separate args for `codemirror`, `csslint`, `jshint`, and `htmlhint`.
* Prefix `codemirror` script and style handles with `wp-` to prevent collisions, as also the object is exported as `wp.CodeMirror` in JS.
* Reduce indent size in Customizer code editor instances and Custom HTML widget to use tab size of 2 instead of 4 to save on space.

Weston Ruter 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`.

Weston Ruter 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.

John Blackbourn 28eda6f4bc General: Improve terminology used when referring to installations of WordPress and its extensions.
"Install" is not a noun, and while it might be acceptable to use the verb as a noun, it is not correct. Using the correct
noun, "installation", increases clarity, especially for non-native English speakers.

This change fixes the usage in user-facing text and in developer documentation.

Weston Ruter a193916f46 Customize: Introduce `settings_previewed` arg and getter on `WP_Customize_Manager` which controls whether `WP_Customize_Setting::preview()` should be called on settings.
The `settings_previewed` property eliminates the need for the Customizer components from having to look at global `doing_ajax` state. This is in particular needed when saving settings, as some settings will short-circuit the update operation if they detect no changes are introduced. This is also needed for low-level integrations with the Customizer, such as in REST API endpoints under development.

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.

Featured image support means that attachments can now be imported. Media can be sideloaded from within theme or plugin directories. Like other posts, attachments are auto-drafts until customizer changes are published, and are not duplicated when they already exist in the customized state. Attachment IDs can be used for any number of purposes, much like post IDs. Twenty Seventeen now includes 3 images used as featured images to best showcase the multi-section homepage setup.

As featured image IDs are stored in post meta, it also made sense to add support for page templates. Twenty Seventeen does not include any such templates, but the functionality can be quite important for displaying themes to their best effect.

This adds play/pause controls to video headers, along with voice
assistance, using `wp.a11y.speak`, to make custom video headers more
accessible. To make styling the play/pause button easier for themes,
CSS has been omitted from the default implementation.

This also includes a refactor of the `wp.customHeader` code to introduce
a `BaseHandler` class, which can be extended by plugins and themes to modify
or enhance the default video handlers.

Peter Wilson 11998b4169 Themes: Remove front page restriction from video header functions.
Adds a callback for determining when video headers should be displayed in themes supporting custom headers. By default, video headers are only displayed on the front page of a site.

Theme authors may set a custom callback by passing `'video-active-callback' => 'mytheme_video_active_callback'` as an argument. The default callback is `is_front_page()`.

This introduces the new function `is_header_video_active()` - returns `true` on pages that should display video headers. The return value can be filtered using the new filter of the same name.

Joe McGill 8fa49e77bd Themes: Improve support for placeholders in default headers.
When themes register default headers, they can use sprintf style placeholder
strings in place of the template directory URI, which WordPress transforms
in several places by running the value of

This fixes a few places where WordPress skipped the `sprintf()` step and
referenced the `get_theme_support()` value directly.

Starter content is staged in the customizer and does not go live unless the changes are published. Initial starter content is added to Twenty Seventeen.

* The `fresh_site` flag is cleared when a published post or page is saved, when widgets are modified, or when the customizer state is saved.
* Starter content is registered via `starter-content` theme support, where the argument is an array containing `widgets`, `posts`, `nav_menus`, `options`, and `theme_mods`. Posts/pages in starter content are created with the `auto-draft` status, re-using the page/post stubs feature added to nav menus and the static front page controls.
* A `get_theme_starter_content` filter allows for plugins to extend a theme's starter content.
* Starter content in themes can/should re-use existing starter content items in core by using named placeholders.
* Import theme starter content into customized state when fresh site.
* Prevent original_title differences from causing refreshes if title is present.
* Ensure nav menu item url is set according to object when previewing.
* Make sure initial saved state is false if there are dirty settings without an existing changeset.
* Ensure dirty settings are cleaned upon changeset publishing.

Joe McGill 030bc377dd Themes: Enable video in custom headers.
This adds the ability for themes to add support for videos in custom headers
by passing `'video' => true` as an argument when adding theme support for
custom headers.

Custom video headers are managed through the “Header Visuals” (i.e. “Header Image”)
panel in the Customizer where you can select a video from the media library or set a
URL to an external video (YouTube for now) for use in custom headers.

This introduces several new functions:

`has_header_video()` – Check whether a header video is set or not.
`get_header_video_url()` – Retrieve header video URL for custom header.
`the_header_video_url()` – Display header video URL.
`get_header_video_settings()` – Retrieve header video settings.
`has_custom_header()` – Check whether a custom header is set or not.
`get_custom_header_markup()` – Retrieve the markup for a custom header.
`the_custom_header_markup()` – Print the markup for a custom header.

And a new file, `wp-includes/js/wp-custom-header.js` that handles loading videos
in custom headers.

This also enables video headers in the Twenty Seventeen and Twenty Fourteen themes.

Pascal Birchler f54558e75b General: Introduce a `wp_list_sort()` helper function.
In addition to `wp_list_filter()` for filtering a list of objects, and `wp_list_pluck()` for plucking a certain field out of each object in a list, this new function can be used for sorting a list of objects by specific fields. These functions are now all contained within the new `WP_List_Util()` class and `wp_list_sort()` is used in various parts of core for sorting lists.

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.

Weston Ruter d84c343cc6 Customize: Let `static_front_page` section be contextually active based on whether there are any published pages.
If there are no pages when the customizer is opened, the `static_front_page` section will be hidden. As soon as a page is created in the customizer session, the `static_front_page` section will be revealed. Previously the section would not be registered if there were no pages. Page stubs created via nav menus will appear in the `dropdown-pages` controls for `page_for_posts` and `page_on_front`, and such page stubs will thus cause the `static_front_page` section to appear. Plugins that facilitate page creation in the customizer by filtering `get_pages` will also cause the section to appear.

* Ensures that notifications will be re-rendered if a notification's `message` changes but the `data` and `type` remain the same.
* Adds explicit support for the `Notification` class to have a `setting` property, ensuring that the property is set whereas previously it was dropped.

Scott Taylor 6a529648cf Bootstrap: Autoload classes using a Composer-generated PHP 5.2-compatible Autoloader.
* `wp-admin` and `wp-includes` are scanned for classes to autoload
* Several 3rd-party and Ryan McCue-shaped libraries are excluded when the classmap is generated, see `composer.json`: `autoload.exclude-from-classmap`
* `wp-vendor/autoload_52.php` is included at the top of `wp-settings.php` - no changes need to be made to unit tests to include the autoloader
* An avalanche of `require()` and `require_once()` calls that loaded class files have been removed from the codebase.

The following files have been added to `svn:ignore` - they are not 5.2-compatible and fail during pre-commit:
* src/wp-vendor/autoload.php
* src/wp-vendor/composer/autoload_real.php
* src/wp-vendor/composer/autoload_static.php
* src/wp-vendor/composer/ClassLoader.php

We favor these files instead:
* src/wp-vendor/autoload_52.php
* src/wp-vendor/composer/autoload_real_52.php
* src/wp-vendor/composer/ClassLoader52.php

When new PHP classes are added to the codebase, simply run `composer install` or `composer update` from the project root to update the autoloader.

The future is now.

Weston Ruter 87b0a1b989 Customize: Add setting validation model and control notifications to augment setting sanitization.
When a setting is invalid, not only will it be blocked from being saved but all other settings will be blocked as well. This ensures that Customizer saves aren't partial but are more transactional. User will be displayed the error in a notification so that they can fix and re-attempt saving.

PHP changes:

* Introduces `WP_Customize_Setting::validate()`, `WP_Customize_Setting::$validate_callback`, and the `customize_validate_{$setting_id}` filter.
* Introduces `WP_Customize_Manager::validate_setting_values()` to do validation (and sanitization) for the setting values supplied, returning a list of `WP_Error` instances for invalid settings.
* Attempting to save settings that are invalid will result in the save being blocked entirely, with the errors being sent in the `customize_save_response`. Modifies `WP_Customize_Manager::save()` to check all settings for validity issues prior to calling their `save` methods.
* Introduces `WP_Customize_Setting::json()` for parity with the other Customizer classes. This includes exporting of the `type`.
* Modifies `WP_Customize_Manager::post_value()` to apply `validate` after `sanitize`, and if validation fails, to return the `$default`.
* Introduces `customize_save_validation_before` action which fires right before the validation checks are made prior to saving.

JS changes:

* Introduces `wp.customize.Notification` in JS which to represent `WP_Error` instances returned from the server when setting validation fails.
* Introduces `wp.customize.Setting.prototype.notifications`.
* Introduces `wp.customize.Control.prototype.notifications`, which are synced with a control's settings' notifications.
* Introduces `wp.customize.Control.prototype.renderNotifications()` to re-render a control's notifications in its notification area. This is called automatically when the notifications collection changes.
* Introduces `wp.customize.settingConstructor`, allowing custom setting types to be used in the same way that custom controls, panels, and sections can be made.
* Injects a notification area into existing controls which is populated in response to the control's `notifications` collection changing. A custom control can customize the placement of the notification area by overriding the new `getNotificationsContainerElement` method.
* When a save fails due to setting invalidity, the invalidity errors will be added to the settings to then populate in the controls' notification areas, and the first such invalid control will be focused.
