Original commit message from CVS: API docs. revived _buffer_ref_by_count fast types for scheduler and bin. error checking on plugin features; removed some prototypes that were not implemented (gst_pipeline_iterate comes to mind) remove gst_pad_event until we know what it's supposed to do. remove sinesrc, it wasn't compiles anymore, so... updates to various elements that used the old event API.
