Pedro F. Giffuni 8a16b7a18f 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.

Alan Somers da61e79c42 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.

Bryan Drewery cf990407e1 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.

Mikolaj Golub 3cfa2135c5 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`.

  but they can be turned on with a -T or -C, respectively.
