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.
