Postings were sent to -arch@ on 2019/09/13 and 2019/10/01, proposing and
confirming a removal of these scripts on 2019/10/31, due to significant work
needed to bring this into the modern world and nobody having done this work
in the past couple of years. No objections or proposed work was raised in

separate repo for archival purposes if any users of it show interest in
doing so.

addressed in a future commit.

  them unsigned I made the possible overflows hard to detect,
  and it only saved 1 bit which isn't principal, even less now
  that the underlying issue with the total of virtual memory has
  been fixed.  (For the record, it will overflow with >=2T of
  VM total, with 32-bit ints used to keep counters in pages.)

- While here, fix printing of other "struct vmtotal" members
  such as t_rq, t_dw, t_pw, and t_sw as they are also signed.

- Fix overflow bugs in sysctl(8), systat(1), and vmstat(8)
  when printing values of "struct vmmeter" in kilobytes as
  they don't necessarily fit into 32 bits.  (Fix sysctl(8)
  reporting of a total virtual memory; it's in pages too.)
