WARNING: This is a significant change. If you are risk-averse and
working on something, hold off syncing.
Defined macros for core CPU functions: CPU_INIT, CPU_RESET, CPU_EXIT,
CPU_EXECUTE, along with macros for the name and for calling, in the
spirit of the devintrf.h macros. More will come later.
Changed init, reset, exit, and execute interfaces to be passed a
const device_config * object. This is a fake object for the moment,
but encapsulates the machine pointer and token. Eventually this will
be a real device.
Changed the CPU IRQ callbacks to a proper type, and added a device
parameter to them.
Updated all CPU cores to the new macros and parameters.
Note that this changes the way we "pointer"-ify cores. I'll send an
update shortly.
