dcc2fb3707 systat: Avoid incorrect reallocation in pigs.c
Stop free() even if kvm_getprocs as we can come back but set nprocs = 0.
Check nprocs in showpigs() to ensure not try displaying with kvm_getprocs failed.
Current code can have pt with non-null after kvm_getprocs() failure.

Replace to realloc for simpler operations.

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.

1e902b3b7e - Avoid accessing window properties directly, instead, use accessors.
This should be no-op for now, but allows the code to work if we
   move to NCURSES_OPAQUE.
 - Use calloc() instead of malloc+bzero.

627d915e25 Whitespace fixes.
- Remove redundant empty lines.
- Replace ^L by \014. This allows you to safely cat/grep/etc this file
  without causing confusion.

b61ce5b0e6 - Move all of the PS_ flags into either p_flag or td_flags.
- p_sflag was mostly protected by PROC_LOCK rather than the PROC_SLOCK or
   previously the sched_lock.  These bugs have existed for some time.
 - Allow swapout to try each thread in a process individually and then
   swapin the whole process if any of these fail.  This allows us to move
   most scheduler related swap flags into td_flags.
 - Keep ki_sflag for backwards compat but change all in source tools to
   use the new and more correct location of P_INMEM.

8be3f374a7 - Stop computing %CPU for the imaginary idle process; we now
have real idle processes for that.

- Fix the display on SMP by not scaling the sum of %CPU down
  to 1.  Instead, display raw data as computed by the kernel,
  like in top(1).

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.

1f7d250182 Change the proc information returned from the kernel so that it
no longer contains kernel specific data structures, but rather
only scalar values and structures that are already part of the
kernel/user interface, specifically rusage and rtprio. It no
longer contains proc, session, pcred, ucred, procsig, vmspace,
pstats, mtx, sigiolst, klist, callout, pasleep, or mdproc. If
any of these changed in size, ps, w, fstat, gcore, systat, and
top would all stop working. The new structure has over 200 bytes
of unassigned space for future values to be added, yet is nearly
100 bytes smaller per entry than the structure that it replaced.

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.
