Correct a long-standing design flaw: device configuration state
is now separate from runtime device state. I have larger plans for devices, so there is some temporary scaffolding to hold everything together, but this first step does separate things out. There is a new class 'running_device' which represents the state of a live device. A list of these running_devices sits in machine->devicelist and is created when a running_machine is instantiated. To access the configuration state, use device->baseconfig() which returns a reference to the configuration. The list of running_devices in machine->devicelist has a 1:1 correspondance with the list of device configurations in machine->config->devicelist, and most navigation options work equally on either (scanning by class, type, etc.) For the most part, drivers will now deal with running_device objects instead of const device_config objects. In fact, in order to do this patch, I did the following global search & replace: const device_config -> running_device device->static_config -> device->baseconfig().static_config device->inline_config -> device->baseconfig().inline_config and then fixed up the compiler errors that fell out. Some specifics: Removed device_get_info_* functions and replaced them with methods called get_config_*. Added methods for get_runtime_* to access runtime state from the running_device. DEVICE_GET_INFO callbacks are only passed a device_config *. This means they have no access to the token or runtime state at all. For most cases this is fine. Added new DEVICE_GET_RUNTIME_INFO callback that is passed the running_device for accessing data that is live at runtime. In the future this will go away to make room for a cleaner mechanism. Cleaned up the handoff of memory regions from the memory subsystem to the devices.
