clean up use of interpreter in qt_interpreter_events::enter_debugger_event * qt-interpreter-events.h, qt-interpreter-events.cc (qt_interpreter_events::enter_debugger_event): New argument, fcn_file_name. Use it instead of calling interpreter functions to determine whether to open the file * event-manager.h (event_manager::enter_debugger_event): New argument, fcn_file_name. * pt-eval.cc (debugger::repl): Pass fcn name and file name to enter_debugger_event.
