Original commit message from CVS: * docs/manual/advanced-autoplugging.xml: * docs/manual/basics-helloworld.xml: * docs/manual/basics-pads.xml: * docs/random/ds/0.9-suggested-changes: * gst/gstelement.c: (gst_element_class_init), (gst_element_seek): * gst/gstelement.h: * gst/gstevent.h: * gst/gstformat.h: * gst/gstquery.h: * gst/gststructure.c: (gst_structure_value_get_generic_type), (gst_structure_parse_array), (gst_structure_parse_value): * gst/gstvalue.c: (gst_type_is_fixed), (gst_value_list_prepend_value), (gst_value_list_append_value), (gst_value_list_get_size), (gst_value_list_get_value), (gst_value_transform_array_string), (gst_value_serialize_array), (gst_value_deserialize_array), (gst_value_intersect_array), (gst_value_is_fixed), (_gst_value_initialize): * gst/gstvalue.h: 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).
