* 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. :-)
