Patch - sid/include/sidcpuutil.h

[Dave Brolley <brolley at redhat dot com>]

Hi,

The attached patch makes the function basic_cpu::stepped virtual and 
public. This allows it to be overridden by a derived class so that the 
value passed to it may be evaluated and perhaps changed before being 
driven on the step_cycles_pin. One purpose for this might be to allow 
the component to unschedule itself by driving a value of 0.

This has been approved by Franck Eigler and committed.
