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.

Clicking on the Edit Menu button focuses on the corresponding nav menu section. Upon collapsing the nav menu section, the focus is returned to the Custom Menu widget instead of taking the user to the menus root panel. In this way, the back button behavior is modified once to serve as breadcrumb/history navigation. The Edit Menu button with the breadcrumb back button behavior greatly reduce the number of UI interactions needed to edit a menu referenced in a Custom Menu widget.

Also use 'back-compat' in some inline comments where backward compatibility is the subject and shorthand feels more natural.

The plugin details modal can be invoked from several screens. There's now a new
`.open-plugin-details-modal` CSS class to be used in combination with the
`.thickbox` CSS class that adds everything needed for accessibility.
- Adds an ARIA role `dialog` and an `aria-label` attribute to the modal
- Adds a `title` attribute to the iframe inside the modal
- Constrains tabbing within the modal
- Restores focus back in a proper place when closing the modal
Also, improves a bit the native Thickbox implementation: it should probably be
replaced with some more modern tool but at least keyboard focus should be moved
inside the modal.

Removes overly-zealous filtering of autofocus panels, sections, and controls which are unrecognized or for which the user doesn't have the capability to focus (in which case it would no-op anyway). Also defers autofocus logic until instances are created, even after initial `ready` event.

* Improves parity between partials and controls. A partial or control can be settingless if instantiated with `settings` param as empty array (otherwise, if null, then the partial/control ID is used).
* Eliminate need to create dummy settings that serve no purpose except to place a control in the UI.
* Removes dummy settings for `create_new_menu` and `new_menu_name`.
* Introduces `WP_Customize_Control::$capability` and `WP_Customize_Partial::$capability`, and if set checks them in the respective `check_capabilities()` methods.
* Prevents PHP fatal error from happening when non-existing settings are provided to control: "Call to a member function `check_capabilities()` on a non-object".
* Fixes issue where nav menu items and widgets were no longer working with selective refresh because cap check was failing.

Backbone, from 1.1.2 to 1.2.3. Underscore, from 1.6.0 to 1.8.3.
The new versions of Backbone and Underscore offer numerous small bug fixes and some optimizations and other improvements. Check the [http://backbonejs.org/#changelog Backbone changelog] and [http://underscorejs.org/#changelog Underscore changelog] for the full details.
The new versions include some significant changes that may break existing code. Plugins or themes that rely on the bundled Backbone and/or Underscore libraries should carefully check functionality with the latest versions and run any available unit tests to ensure compatibility.
Some changes of note that were addressed in core as part of this upgrade:
* `_.flatten` no longer works with objects since Underscore.js 1.7. `_.flatten()` working with objects was an unintended side-affect of the implementation, see [https://github.com/jashkenas/underscore/issues/1904#issuecomment-60241576 underscore#1904]. Check any `_flatten` usage and only flatten arrays.
* As of Backbone 1.2.0, you can no longer modify the `events` hash or your view's `el` property in `initialize`, so don't try to modify them there.
* Since Underscore 1.7, Underscore templates no longer accept an initial data object. `_.template` always returns a function now so make sure you use it that way.

In the Edit Menu screen, each menu item creates 11 form input elements. In menus with more than 71 menu items, often items after the 71st weren't saved. This was because PHP's runtime configuration `max_input_vars` default value is 1000. Large menus exceed this, so PHP didn't populate the `$_POST` superglobal for the latter menu items.
The entire form is now JSON-encoded into a single input which populates `$_POST` manually on form submission.
This was attempted previously in [36506] which was reverted in [36507]. Some form fields were not being slurped into the form's JSON representation, and it did not scale for a site with many posts. This approach fixes those problems.
