Original commit message from CVS: * gst/gstbin.c: (bin_element_is_semi_sink), (gst_bin_change_state): use gst_object_has_ancestor(). * gst/gstobject.c: (gst_object_has_ancestor): * gst/gstobject.h: gst_object_has_ancestor() copied from gstbin.c as it is a usefull function. * tests/instantiate/create.c: (create_all_elements): * tests/lat.c: (handoff_src), (handoff_sink): * tests/sched/runxml.c: (main): * tests/seeking/seeking1.c: (main): * tests/threadstate/threadstate2.c: (bus_handler), (timeout_func), (main): Fix compilation of some tests.
