Original commit message from CVS: - major API breakage (one of the last, I promise...) - GST_PAD_QUERY -> GST_QUERY - GstPadQuery -> GstQuery - Move query definitions to gstquery.h to allow for future dynamic query types. - remove _pad_handles_* in favour of extra format/event functions to make the same checks. - fix elements - Implemented missing query/event/formats functions in gstelement
