7d866d268b Update statistics reporting to use new kernel framework, rename dkstats* 
to a more generic name since it no longer just deals with disk.

228802f437 Split dkreadstats() into dkreadstats(), tkreadstats() and cpureadstats(). 
Similarly for dkswap().
Allows code to only call one of these.
Rename struct _disk to _vminfo to be nearer its contents.
Change 'systat vm' so that it always shows the 'current' cpu times, even
after ':run' or ':boot' commands. The code in vmstat.c doesn't support :run.

9c47d944e4 optimize pool_caches similarly to how I optimized pools before: 
split the single list of pool cache groups into three lists:
completely full, partially full, and completely empty.
use LIST instead of TAILQ where appropriate.

d5b80101e7 do not rely on the pre-evcnt interrupt counter kernel symbols being present. 
if they do not exist, then interrupt stats are all in evcnts.

9be8ac5294 Alternative pid/proc allocater, removes all searches associated with pid 
lookup and allocation, and any dependency on NPROC or MAXUSERS.
NO_PID changed to -1 (and renamed NO_PGID) to remove artificial limit
on PID_MAX.

88df2c4818 The -u option takes an argument, so we need the corresponding : in the 
getopt() string.  Does no one use uvm histories any more, or does
everyone just dump all the histories?

7ec345ff22 In getuptime(), use kread() to get the current time as well as boottime, 
instead of calling time(3).

This makes rate calculations of crash dumps sensible; in contrast,
subtracting the boot time of the crash dump from the current time of the
running system produces a not-very-meaningful number.

3cf4c73d05 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.

f80c7eebd7 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.
