Collapsed device_config and device_t into one class. Updated all
existing modern devices and the legacy wrappers to work in this environment. This in general greatly simplifies writing a modern device. [Aaron Giles] General notes: * some more cleanup probably needs to happen behind this change, but I needed to get it in before the next device modernization or import from MESS :) * new template function device_creator which automatically defines the static function that creates the device; use this instead of creating a static_alloc_device_config function * added device_stop() method which is called at around the time the previous device_t's destructor was called; if you auto_free anything, do it here because the machine is gone when the destructor is called * changed the static_set_* calls to pass a device_t & instead of a device_config * * for many devices, the static config structure member names over- lapped the device's names for devcb_* functions; in these cases the members in the interface were renamed to have a _cb suffix * changed the driver_enumerator to only cache 100 machine_configs because caching them all took a ton of memory; fortunately this implementation detail is completely hidden behind the driver_enumerator interface * got rid of the macros for creating derived classes; doing it manually is now clean enough that it isn't worth hiding the details in a macro
