GstElement::new-pad -> pad-added, GstElement::state-change ->
state-changed, GstValueFixedList -> GstValueArray, add format and
flags as their own arguments in gst_element_seek() (should improve
"bindeability"), remove function generators since they don't work
under a whole bunch of compilers (they were deprecated already
anyway).
