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.
C++11 range-based for loops can now iterate over simple_list, tagged_list, core_options, device_t::subdevice_list, device_t::interface_list, render_primitive_list and all subclasses of the above, and much code has been refactored to use them. Most core classes that have these lists as members now have methods that return the lists themselves, replacing most of the methods that returned the object at an owned list's head. (A few have been retained due to their use in drivers or OSD.)
device_t now manages subdevice and interface lists through subclasses, but has given up the work of adding and removing subdevices to machine_config.
memory_manager has its tagged lists exposed, though the old rooted tag lookup methods have been removed (they were privatized already).
* Allow std::string to pass through core_file unmolested (reduces temporary allocations)
* Make zip/7z instances of same class with uniform interface
* zippath browsing is broken at the moment
This is another step towards transparent archive support. It's now
possible to access zip and 7z archives with the same code. Nothing is
taking advantage of it yet. There's now some very similar code in
fileio.cpp and clifront.cpp that could be folded at some point.
