sclp_ocf.c is the only way to get the cpc name, as it registers the sole event handler for the ocf event. By creating a new global function that copies that name, we make it accessible to the world which longs to retrieve it. Additionally we now also store the cpc name as EBCDIC, so we don't have to convert it to and from ASCII if it is requested in native encoding.
