* Implemented dladdr() in the runtime loader. This is like a gazillion times

faster than before.
* This also solves a TODO in dladdr(), although I did not use
  get_library_symbol() as I didn't quite see how that could fit as the comment
  suggested; there is now a new function get_symbol_at_address() for this.
