Original commit message from CVS: * gst/adder/gstadder.c: (gst_adder_setcaps), (gst_adder_query_duration), (gst_adder_query), (forward_event), (gst_adder_src_event), (gst_adder_sink_event), (gst_adder_class_init), (gst_adder_finalize), (gst_adder_request_new_pad), (gst_adder_collected): * gst/adder/gstadder.h: Updated some docs. Added comments and FIXMEs all over the place. Improve debugging info. Fix leak on finalize by not calling the parent. Implement duration query. Make event forwarding threadsafe. Correctly send NEWSEGMENT at start and after flush. Handle EOS correctly. Post error when not negotiated. * tests/check/elements/adder.c: (GST_START_TEST): Added FIXME in the test.
