improve exit sequence for GUI
* octave-link.h, octave-link.cc (octave_link::accepting_events):
Delete variable and all uses.
(octave_link::link_enabled): New data member.
(octave_link::octave_link): Don't set octave_exit. Initialize
link_enabled.
(octave_link::do_exit): Delete definition. Now pure virtual.
Return bool.
(octave_link::exit): Call instance->do_exit.
(octave_link::enabled): New function.
(ocave_link::process_events): New arg, disable. Optionally disable
event processing.
Use octave_link::enabled instead of instance_ok everywhere except for
octave_link::exit.
(octave_link::cleanup_instance): Delete.
* octave-qt-link.h, octave-qt-link.cc
(octave_qt_link::octave_qt_link): Accept thread as argument.
Don't connect main_thread::finished signal.
(octave_qt_link::~octave_qt_link): Don't delete main_thread.
(octave_qt_link::do_exit): Emit exit_signal and return true.
(octave_qt_link::exit_signal: New signal.
(octave_qt_link::void octave_thread_finished_signal): Delete.
* main-window.h, main-window.cc (main_window::_octave_main_thread):
New member variable.
(main_window::main_window): Initialize _octave_main_thread and
_octave_qt_link to 0.
(main_window::~main_window): Don't call octave_link::connect_link.
Delete _octave_main_thread.
(main_window::exit): Accept exit status as argument and call
QApplication::exit instead of quit.
(main_window::construct): Don't connect qApp::aboutToQuit to
main_window::prepare_to_exit.
(main_window::construct_octave_qt_link): Create _octave_main_thread
and pass to _octave_qt_link. Don't connect
_octave_qt_link::octave_thread_finished to main_window::exit.
Connect _octave_qt_link::exit_signal to main_window::exit.
* toplev.h, toplev.cc (main_loop): If quitting_gracefully, just return
exit status instead of calling clean_up_and_exit.
(do_octave_atexit): Now static. Call octave_link::process_events with
disable arg set to true.
(octave_atexit_functions): Now static.
(clean_up_and_exit): New argument, safe_to_return.
Call octave_link::exit and possibly return or wait for
octave_link::exit to terminate the process.
* octave.cc (octave_execute_interpreter): Don't alter return value
from main_loop. Pass safe_to_return = true to clean_up_and_exit.
Return retval instead of 0.
(octave_initialize_interpreter): Don't call atexit.
