* add many missing declarations to sections * GstController has been removed, update docs * skip GstIndex when generating documentation * rephrase so gtkdoc doesn't imagine return value * add missing argument description for gst_context_new() * document GstOutputSelectorPadNegotiationMode and move to header-file https://bugzilla.gnome.org/show_bug.cgi?id=719614
