Currently the entities store their configurations into a display list. Adapt this such that the code can be configured into a body directly, allowing greater flexibility and control of the content. All users of vsp1_dl_list_write() are removed in this process, thus it too is removed. A helper, vsp1_dl_list_get_body0() is provided to access the internal body0 from the display list.
