mrg | add iostat -X option, limited alternative statistics.
this is like the "-D" option, except it skips the xfers/s, and
reports MB/s instead of KB/s. allows for far more devices to
be displayed per line by default (about 50% more.)

kre | Significant changes to output layout methods - except for -x and -y
which have not (yet) been touched (-xD needs *serious* improvements).
While this still has no run-time configurability, it is now easy to
adjust the column widths in the source and recompile. Dynamic (auto)
column width sizing is probably out of the question (requires predicting
the future) but options to allow the widths to be set isn't out of the
question.
The columns are now (mostly) considerably wider than they were before,
hence wider windows are needed to view the same info. In an 80
column window the default display (with tty & cpu included) displays
just 2 drives. 160 columns will fit 7 (but with -I, just 4).
One new option added (-z) suppresses output which is true 0 (but still
prints 0 for values rounded down to 0) for everything except tty stats.
For drive output, the drive must have done nothing during the interval
to get its output data blanked.
Also options -H h -W w to set the output size (page height & width), the
former used to decide when to print headers, and the latter to calculate
the number of drives to print when no drive names were given. Env vars
LINES and COLUMNS are used if the options are not given, with fallback
to the terminal size (if output is to a terminal, and its sizes are
known), and if all else fails, 20 lines, 80 columns. Specifying 0
means unlimited (infinite). So "iostat -W 0" will show all of the
drives, across one (often very) long line. Wedges count as drives.
When drives are specified, the output will now appear in the order they were
given on the command line, rather than the order the system discovered them
during auto-configuration. If specified as an fnmatch(3) pattern, drives that
match will appear in auto-conf order, but that's generally what is wanted.
When none are specified, you still get the first N (however many fits based
upon the options selected) in auto-conf order (usually useless, more so now
given that less will fit).
Lastly, for those who looked at the patch I sent to current-users@
and were horrified at how kludgey it was, rest assured, that was just
a quick hack to demonstrate what the output format changes would look
like. This version (I hope) is not nearly so disgusting.

mlelstv | branches: 1.25.10; 1.25.12;
Enhance disk metrics by calculating a weighted sum that is incremented
by the number of concurrent I/O requests. Also introduce a new disk_wait()
function to measure requests waiting in a bufq.
iostat -y now reports data about waiting and active requests.
So far only drivers using dksubr and dk, ccd, wd and xbd collect data about
waiting requests.

mrg | 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.

scottr | `Kb' means kilobits, `Mb' means megabits. Since we're talking about bytes,
not bits, use the uppercase `B' when reporting statistics, and be explicit
about it where appropriate. Noticed by J.T.

usr.sbin/iostat/iostat.c: revision 1.63
usr.sbin/iostat/iostat.8: revision 1.24
support fnmatch(3) patterns for disknames. eg, "iostat wd*" works now.
update the default disk number selection to note that it uses the current
terminal size to fit disks, not hard coded 4.
extend the "tout" column to 5 characters, it's really common on a modern
machine to have eg, build output way more than 9999 chars/sec.
this doesn't affect the default disk list on an 80-char wide screen.
