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).
[Aaron Giles]
* these classes now no longer take a resource_pool; everything is
managed globally -- this means that objects added to lists must be
allocated with global_alloc
* added new auto_pointer<> template which wraps a pointer and auto-frees
it upon destruction; it also defaults to NULL so it doesn't need to
be explicitly initialized
* moved tagged_list template to tagmap.h
Redo of the low-level memory tracking system: [Aaron Giles]
* moved low-level tracking out of emu\emualloc into lib\util\corealloc
so it can be shared among all components and used by core libraries
* global_alloc and friends no longer use a resource pool to track
allocations; turns out this was a wholly redundant system that wasted
a lot of memory
* removed global_resource_pool entirely
* added global_free_array to delete arrays allocated with
global_alloc_array
* added tracking of object versus array allocation; we will now error
if you use global_free on an array, or global_free_array on an object
Added new utility helper const_string_pool which can be used to
efficiently accumulate strings that are not intended to be modified.
Used by updated makelist and software list code. [Aaron Giles]
Updated png2bdc and makelist tools to not leak memory and use more modern
techniques (no more MAX_DRIVERS in makelist, for example). [Aaron Giles]
Deprecated auto_strdup and removed all uses by way of caller-managed
astrings and the software list rewrite. [Aaron Giles]
Rewrote software list management: [Aaron Giles]
* removed the notion of a software_list that is separate from a
software_list_device; they are one and the same now
* moved several functions into device_image_interface since they really
didn't belong in the core software list class
* lots of simplification as a result of the above changes
Additional notes (no whatsnew):
Moved definition of FPTR to osdcomm.h.
Some changes happened in the OSD code to fix issues, especially regarding
freeing arrays. SDL folks may need to fix up some of these.
The following devices still are using tokens and should be modernized

delete it, which you can't):
