function update_manager_update_ready_form_submit in Drupal 7

Form submission handler for update_manager_update_ready_form().

If the site administrator requested that the site is put offline during the update, do so now. Otherwise, pull information about all the required updates out of the SESSION, figure out what Drupal\Core\Updater\Updater class is needed for each one, generate an array of update operations to perform, and hand it all off to system_authorized_init(), then redirect to authorize.php.
