Pass all three mib items to a sysctl in dkreadstats().

Use the new kernel sysctl sizing code to calculate the number of drives.

iostat(8) and systat(8) support for separate read/write disk statistics.
...
"iostat -x" now shows these (ala linux/solaris), but this is only splitting
the read/write bytes/transactions, not adding any new metrics. "systat
iostat" now has two new commands to switch between combined/separate mode
for both it's numbers & bar modes.

Since the KERN_CP_TIME sysctl reports total clock ticks across all
...
cpus and hz is measured in ticks per cpu, divide tick count by ncpu to
determine elapsed time since last sample.
Fixes I/O rate deflation observed on multiprocessors.

Fix handling of privileges - the gid was given up before dkinit()
...
was called.
Pass the gid to use for KVM access explicitely to dkinit(), the caller
decides whether to call setgid(getgid()) or not.

- change setgid kmem programs (that lend themselves to this) so setegid(getgid())
...
and the top, and then set the effective gid back to kmem around the call to
kvm_openfiles(). this reduces the time group kmem is available.
- for those above that also allow this, setgid(getgid()) after the call to
kvm_openfiles() to fully revoke priviledges.
- some KNF
- use err(3) over fprintf(3) in some places
