function form_test_storage_form in Drupal 7

A multistep form for testing the form storage.

It uses two steps for editing a virtual "thing". Any changes to it are saved in the form storage and have to be present during any step. By setting the request parameter "cache" the form can be tested with caching enabled, as it would be the case, if the form would contain some #ajax callbacks.
