Iterate over devices C++11 style
Replace the old device_iterator and its specialized versions with functionally equivalent classes that use standard operators to yield references to devices/interfaces rather than pointers. With range-based for loops, they no longer have to be stored in named variables, though they can also be reused concurrently since the iteration state is now maintained by a subclass. Add a few more typical getters to device_t::subdevice_list.
