(main_window::_ocxtave_qt_event_listener): Delete member variable and
all uses.
main_window::construct_octave_qt_link): connect
_octave_qt_link::octave_thread_finished to main_window::exit.
* octave-qt-event-listener.h, octave-qt-event-listener.cc: Delete.
* libgui/src/module.mk (octave_gui_MOC, noinst_HEADERS,
src_libgui_src_la_SOURCES): Update lists.
* octave-qt-link.h, octave-qt-link.cc
(octave_qt_link::octave_thread_finished): New signal.
(octave_qt_link::~octave_qt_link): Delete main_thread.
(octave_qt_link::octave_qt_link): Connect main_thread::finished and
main_thread::terminated to octave_qt_link::octave_thread_finished
signal.
* octave-event-listener.h: Delete.
* libinterp/interp-core/module.mk (INTERPFCN_INC): Remove it from the
list.
* octave-link.h, octave-link.cc (octave_exit_hook): Delete.
(octave_link::discard_events, octave_link::do_discard_events,
octave_link::exit, octave_link::do_exit): New functions.
(octave_link::event_listener): Delete member variable and all uses.
(octave_link::about_to_exit, octave_link::register_event_listener,
octave_link::do_about_to_exit,
octave_link::do_register_event_listener): Delete.
(octave_link::accepting_events): New member variable.
(octave_link::octave_link): Set octave_exit to octave_link::exit.
Initialize accepting_events.
(octave_link::do_post_event): Only add to gui_event_queue if
accepting_events is true.
