new main program wrapper to handle giving up controlling tty * octave-gui.cc (octave_cli_thread): New class, from QtHandles. (dissociate_terminal): Delete. (octave_start_gui): Third arg is now START_GUI instead of FORK. Don't call dissociate_terminal. If start_gui is false, use octave_cli_thread to start Octave within a QApplication context. * sighandlers.cc (gui_driver_sig_handler): Move to src/main.in.cc. (install_gui_driver_signal_handlers): Move to src/main.in.cc and rename to octave_set_signal_handler. * octave.cc (no_fork_option): Delete. (process_command_line): Don't handle NO_FORK_OPTION. (octave_fork_gui): Move to src/main.in.cc and rename to have_controlling_terminal. * options-usage.h (usage_string, octave_print_verbose_usage_and_exit): Delete --no-fork from text. (long_opts): Delete no-fork from list. (NO_FORK_OPTION): Delete. * run-octave.in: Set OCTAVE_BINDIR in environment before exec-ing Octave binary. * src/Makefile.am: Build octave-gui, octave-cli, and octave instead of octave-cli and octave. * main-gui.cc: Rename from main.cc. Call octave_start_gui and pass START_GUI as parameter. * main.in.cc: New file.
