unwanted sideeffects in the RB_ASKNAME case. This fixes PR/46732. No longer wrap MD cpu_rootconf(), as hp300 port stores reboot information as a side effect. Instead call MI rootconf() from MD code which makes rootconf() now a wrapper to setroot(). Adjust several MD routines to set the global booted_device,booted_partition variables instead of passing partial information to setroot(). Make cpu_rootconf(9) describe the calling order.
