Original commit message from CVS: * add two apis: * gst_element_connect_elements_many (elem1, elem2, ...) - calls gst_element_connect_elements() in order - should be called gst_element_connect_many, but we need to rename gst_element_connect_elements first - simplifies common-case code * gst_bin_add_many (bin, elem1, ...) - calls gst_bin_add on all of the elems - again, simplifying common code
