425e829981 Make the "KB/s" field one character shorter (by reducing the precision)
and use the space to make the "tps" one character longer.

It makes the iostat(8) output a bit less messed up.

872b698bd4 General further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 3-Clause license.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.

Renumber cluase 4 to 3, per what everybody else did when BSD granted

9a0871ec20 When iostat(8) receives SIGINT while running with "-w" or "-c", it will now
print statistics one more time before exiting. Also, it now implements the
wait using setitimer instead of sleep, so the waits will be more consistent
when the system is heavily loaded.

44973a75bb Update dependencies after r291406 added libelf to libkvm.
Unfortunately filemon/meta mode tracks all indirect dependencies here
since ld(1) is reading libelf when linking in libkvm.  Churn would be
reduced if this was able to be limited to direct dependencies.

fa6bd7906a Change iostat -Ix to display total duration of transactions instead
of average duration, and total busy time instead of %.

This looks more useful when one runs `iostat -Ix` periodically to
collect statistics: e.g. now it is possible to calculate busy %
between two runs subtracting total busy times and dividing per time
period.

Average duration and % busy are still available via `iostat -x`.

b886db4a4b Clarify a few details about iostat(8) behavior:
- The default repeat count for iostat(8) is 1 unless there
  was a -w on the command line.

- A -x display doesn't include TTY or CPU stats by default
  but they can be turned on with a -T or -C, respectively.

The columns for tty input and output may bump against each other

problem.

0d6a982e10 Fix the device name spacing.
The old logic padded the device name out but assumed the unit number was one digit

Assemble the full device name in a temporary buffer and then calcluate padding
based on that string.

eab3a8645a Repeat iostat header after rows-3 instead of a hardcoded 20.
Use ioctl() to get the window size in iostat(8), and force a new
header to be prepended to the output every time the current
window size changes.  Change the number of lines before each
header to `rows - 3' when the terminal is resized, so that the
full terminal length can be used for output lines.
