Weston Ruter 5dae1386aa Customize: Ensure that a setting (especially a multidimensional one) can still be previewed when the post value to preview is set after `preview()` is invoked.
* Introduce `customize_post_value_set_{$setting_id}` and `customize_post_value_set` actions which are done when `WP_Customize_Manager::set_post_value()` is called.
* Clear the `preview_applied` flag for aggregated multidimensional settings when a post value is set. This ensures the new value is used instead of a previously-cached previewed value.
* Move `$is_preview` property from subclasses to `WP_Customize_Setting` parent class.
* Deferred preview: Ensure that when `preview()` short-circuits due to not being applicable that it will be called again later when the post value is set.
* Populate post value for updated-widget with the (unsanitized) JS-value in `WP_Customize_Widgets::call_widget_update()` so that value will be properly sanitized when accessed in `WP_Customize_Manager::post_value()`.

Weston Ruter 268626d061 Customize: Exclude `referer` URL from being used for Close link if it is `customize.php`.
This fixes an edge case where the Close button could never link the user out of the Customizer, if the user initially accessed it without a `url` param and then clicked a link (provided by a plugin) that took them to another `customize.php` URL.

Weston Ruter 93bcd86b2a Customize: Reduce peak memory usage by JSON-encoding settings and controls individually.
When there are hundreds of settings and controls (e.g. nav menu items and widget instances) the resulting object that is JSON-encoded can become very large, and `wp_json_encode()` can consume a lot of memory to serialize it. By breaking down the serialization into multiple calls the peak memory usage can be kept in line.

Moves logic out of `wp-admin/customize.php` into the `WP_Customize_Manager` class with new methods:

 * `is_ios()`
 * `get_document_title_template()`
 * `get_preview_url()`/`set_preview_url()`
 * `get_return_url()`/`set_return_url()`
 * `get_autofocus()`/`set_autofocus()`
 * `customize_pane_settings()`

Includes unit tests for these methods, for which the logic was formerly untestable in `customize.php`.

This was broken since 4.0 and the introduction of user session tokens. The nonces are now tied to session tokens as opposed to user IDs, and thus they change with each re-login.
Custom nonces can be added through the `customize_refresh_nonces` filter. On a successful refresh request the JavaScript API will trigger a `nonce-refresh` event. See widget's update nonce as an example.

Dominik Schilling 9d162f0945 Ensure that `WP_Customize_Setting::value()` returns default value for setting if not dirty.
There was regression introduced by #28580 where only changed (dirty) settings now are POST'ed to the Customizer preview.

* Allow WP_Customize_Manager::post_value() to accept a second $default argument.
* Introduce WP_Customize_Manager::unsanitized_post_values() for accessing previously-private member variable _post_values.
* Do require_once instead of require for Customizer classes.
* Add unit tests for WP_Customize_Manager and WP_Customize_Setting.
