octave: libinterp/corefcn/error.cc annotate

annotate libinterp/corefcn/error.cc @ 27161:7883e6e71b0a

additional refactoring of error handling functions * error.h, error.cc. Move most functions inside error_system class. Global non-member functions now get interpreter error_system object and call class member fuctions through that object. * graphics.cc (base_graphics_object::remove_all_listeners): Use interpreter_try instead of directly saving and restoring error systsem state here. * interpreter.cc (interpreter::interpreter): Don't call initialize_default_warning_state. That is now handled by constructing the error_system object.
