Customize: Introduce starter content and site freshness state. A theme can opt-in for tailored starter content to apply to the customizer when previewing the theme on a fresh install, when `fresh_site` is at its initial `1` value. 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.

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.

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.

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.

Customize: Introduce starter content and site freshness state.

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.
