Yet another kstat_chain_update check. Added machine.cpu_stat_kstat[x] =

* open.c (glibtop_get_kstats): Yet another kstat_chain_update
        check. Added machine.cpu_stat_kstat[x] = NULL when processor
        x is not configured.

        * procdata.c (glibtop_get_proc_credentials_s): Read prcred
        structure from /proc.

        * procstate.c (glibtop_get_proc_state_s): Added ruid, rgid,
        has_cpu, processor and last_processor.

        * procuid.c (glibtop_get_proc_uid_s): Added priority, nice,
        suid, sgid, ngroups and groups. The last four will be
        filled only if our process has the authority to read prcred
        structure of another process.

	It's a bit untested for now. :-)
