This unifies the standard backtracer and the new stacktrace in memory backtracer. The standard one is converted to use callbacks and then reimplement stacktrace using new callbacks. The main advantage is that stacktrace can now use the new dwarf2 unwinder and avoid false positives in many cases. I kept it simple to make sure the standard backtracer stays reliable.
