octave: libinterp/corefcn/error.cc annotate

annotate libinterp/corefcn/error.cc @ 27472:c0883bfc0f36

simplify evaluator logic for try-catch command * pt-eval.cc (tree_evaluator::visit_try_catch_command): Simplify function logic. * error.h, error.cc (make_stack_map, make_stack_frame_list): Now public static functions in the error_system class. Change all uses. (bt_fieldnames, bt_fields): Move inside octave namespace.
