* Input ports are now maintained hierarchically. At the top level are input ports, which contain a list of fields. Each field represents one or more bits of the port. Certain fields such as DIP switches and configuration switches contain a list of settings, which can be selected. DIP switch fields can also contain a list of DIP switch locations. * Normalized behavior of port overrides (via PORT_INCLUDE or by defining multiple overlapping bits). All fields within a port are kept in strict increasing bit order, so altered DIP switches are now kept in the appropriate order. This addresses MAMETesters bug 01671. * Live port state is now fully separate from configured state. This is manifested in a similar way to devices, where a const list of ports can be managed either offline or live. Each port has a pointer to an opaque set of live state which is NULL when offline or valid when live. Each port also has a running_machine * which is also NULL when offline. * Because of this new arrangement, the conversion from tokens to a list of ports now requires reasonably complex memory allocation, so these port lists must be explicitly allocated and freed (they are not mantained by automatic resource allocation). * Custom and changed callbacks now take a pointer to a field config instead of a running machine. This provides more information about what field triggered the change notification. The machine can be found by referenced field->port->machine. * The inptport.c module has been cleaned up and many ambiguities resolved. Most of this is internal, though it did result in osd_customize_inputport_list() being changed to osd_customize_input_type_list(). The parameter to this function is now a linked list instead of an array, and the structures referenced have been reorganized somewhat. * Updated config.c to pass machine parameters to its callbacks. * Updated validity checks, XML output, and UI system to handle the new structures. * Moved large table of default input settings to a separate include file inpttype.h. * Removed gross hacks in trackfld and hyperspt NVRAM. These may be broken as a result.
