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.

fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

c19a20a7d1 Dynamically resize the Disk column. It was too narrow for modern
disk device names such as da0s1b.  So we also get rid of the nasty
constant 5 scattered over the code.

Implementing this change is a good chance to improve other bits
around it: init saved lengths early, always check return value from
kvm_getswapinfo().

cb059cfe92 Fix the swap display further:
1) Resize the Used column to avoid screen overflow if BLOCKSIZE is long.
2) Track the current swap configuration so that its changes don't break
   the display.

1f4d2a1d84 Start fixing the "swap" display by saving one horizontal position.
Now the display won't overflow the 80-char row if BLOCKSIZE=1024.
The new spacing is also consistent with the "pigs" display.

8aa22952a9 Show the load average in the tcp display (it was already shown, perhaps
not very usefully, in all other displays).  This was the original point
of the PR.

Move the load average up by 2 so that it starts in row 0 for all windows
(2 lines above it were wasted for all other windows except vmstat).
Move everything below it up by 2 or 3 (3 for icmp and icmp6 which had
an extra blank line due from not compensating for the foot-shooting in
note (3); only ip and ip6 compensated).  Reduce the magic numbers related
to this.

Notes by the submitter:
%%%
1. All the subwin() calls are identical using #define MAINWIN_ROW 3
    (systat.h).
2. The load average is at the top of the window.
3. Each display starts on the fourth line.  I made changes to those
    displays that shifted the start line (i.e., icmp).  This entailed a
    lot of changes within the comments at the top of those displays.
4. For ip6, I shifted the "Input next-header histogram" column down one
    row to separate it from "IPv6 Output".  I raised "bad scope packets"
    and "address selection failed" up one row to stay with "IPv6 Input"
    (valid?).  They were down one row to probably line up at the bottom,
    but I think they should stick with their fellow items in a column.
5. I condensed ifstat a bit.  It had a lot of empty rows.

342e2faa09 Get rid of setgid kmem for systat, and while being there, fix some bugs
and compiler warnings.
The data for network statistics are still obtained via the kvm interface
if systat was started with the needed privileges, otherwise sysctls are
used. The reason for this is that with really many open sockets, the
sysctl method is probably slower, but it systat -netstat is probably not
really usable in either mode under these conditions.

448b84a0e4 o Use snprintf rather than sprintf
o Add more checks for buffer overflows
o Use snprintf rather than strcat/cpy and have better checks for max
  length exceeded.

Most of these changes are not exploitable buffer overruns, but it never
hurts to be safe.
