Inputs marked as optional should be controls that are not required for normal operation and may not be hooked up on actual hardware, but are still worth emulating because the hardware does respond to them in some way. Currently this flag is only exposed through the Lua interface and "reqbuttons" XML field; the intent is for frontends to map all optional buttons by default if this is possible and convenient. MT #6136 has inspired the addition of this flag to gijoe and clones.
Remove the generally useless PORT_UNUSED to make way for PORT_OPTIONAL; IPT_UNUSED, which most drivers were using already, is a better way of disabling unused fields. (nw)
- Completely move mouse hit testing down into the UI input module. This reduces some dependencies.
- Never return a null pointer from ioport_field::name() to prevent potential crashes. All anonymous inputs are classified as INPUT_CLASS_INTERNAL, so several frontend functions now check type_class instead.
- Correct a couple of typos.
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.
This simplifies an old piece of MESS code that failed to properly classify paddle, pedal, positional and dial inputs, along with many of the less-common digital inputs. MT #06172 should be fixed by this.
The distinction between INPUT_CLASS_MISC and INPUT_CLASS_INTERNAL makes more sense now, though nothing makes use of it.
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).
Make avi_file a class that's held with smart pointers, encapsulate various AVI I/O structures
Make zip_file and _7z_file classes rather than having free functions everywhere
Hide zip/7z class implementation behind an interface, no longer need to call close() to send back to the cache
Don't dump as much crap in global namespace
Add solaris PTY implementation
Improve variable expansion for SDL OSD - supports ~/$FOO/${BAR} syntax
Rearrange stuff so the same things are in file module for all OSDs
Move file stuff into its own module
7z/zip open and destruct are still not thread-safe due to lack of interlocks around cache access
Directory functions still need to be moved to file module
SDL OSD may not initialise WinSock on Windows

Update MAME to use new function
Instantiate ODR-used static constant members
Make some of the UI code more localisable
Remove use of retired functions in tools
-[no]exit_after_playback (default=no)
-[no]record_input (default=no)
Added new UI shortcut to save current timecode (default F12)
Translated variable names and comments to english language
- strprintf is unaltered, but strformat now takes one fewer argument
- state_string_export still fills a buffer, but has been made const
- get_default_card_software now takes no arguments but returns a string
