* AJAX command for updating the value of a hidden form_build_id input element
* on a form. It requires the form passed in to have keys for both the old build
* ID in #build_id_old and the new build ID in #build_id.
*
* The primary use case for this Ajax command is to serve a new build ID to a
* form served from the cache to an anonymous user, preventing one anonymous
* user from accessing the form state of another anonymous user on Ajax enabled
* forms.
*
* This command is implemented by
* Drupal.AjaxCommands.prototype.update_build_id() defined in misc/ajax.js.
