use signal for octave_link::update_dbstop_marker

* octave-qt-link.h (octave_qt_link): Derive from QObject.
(octave_qt_link::update_dbstop_marker_signal): New signal.
* libgui/src/module.mk (octave_gui_MOC): Include
src/moc-octave-qt-link.cc in the list.

* main-window.cc (main_window::construct): Connect
octave_qt_link::update_dbstop_marker_signal to
file_editor::handle_update_dbstop_marker_request.

* octave-qt-link.cc (octave_qt_link::do_update_breakpoint):
Emit signal instead of using event listener.
