This is not the most general interface and will have
to be a wrapper around the more general one.

Ie

void demangle(std::string& t_o, char const* t_i);

std::string demangle(char const* t_i)
{
  std::string t_o;
  demangle(t_o, t_i);
  return t_o;
}

std::string demangle(std::string const& t_i)
{
  return demangle(t_i.c_str());
}

std::string demangle(std::type_info const& i)
{
  return demangle(i.name());
}

Note these wrappers will not cause extra string copy constructors
to be called, as the standard allows (demands?) to skip that.
