76adc1fd42 Add new output-format keywords of LWP and NLWP, which show the thread-id
and number-of-threads tied to a process.  Result can be seen by typing,
e.g.:   ps -HO lwp,nlwp
These new options are not documented yet.  More options will be coming,
and I will update the man page after I get farther along.

4bac4483db Have the main() routine calculate %CPU and (if needed) memory information
when copying per-process info before starting to sort the list.  This way,
sort-by-CPU or sort-by-memory will only calculate values once-per-process,
instead of twice-per-comparison.  Also take advantage of this to simplify
the pscomp() routine.

c23b00b7ca A few more style-fixes from Bruce. The only non-cosmetic change
is to drop a call to setuid() which has not been needed for years.

a9626fb3b4 Since I'm not ready to add the non-standard ADD_PS_LISTRESET feature,
remove the #ifdef for it for now.  I might add the feature for real at
some later date, there isn't much reason for the #ifdef for now.

de1702f459 Fix so `ps' catches and complains about null-values specified for a
process id, instead of using pid==0.  Ie, `ps -p 12,' and `ps -p ,12'
are now errors (instead of being treated like `ps -p 0 -p 12').

bf46a3bf10 Additional tiny adjustment to kludge-option processing so `ps t p0'
is treated like `ps -t p0', instead of changing it to `ps -T p0'.
Note that `ps t' is still changed to `ps -T', since that is one of
the main reasons for this kludge processing...

c675340a5c Rewrite the kludge-option processing to improve how it handles a few
more special situations.  This is the code which process `ps blah',
when "blah" does not include a leading '-'.

This change also removes a long-undocumented BACKWARD_COMPATIBILITY
compile-time option, where:
     ps -options arg1 arg2
(with no '-' on "arg1" and "arg2") was treated as:
    ps -options -N arg1 -M arg2

This also changes `ps' to check for any additional arguments after
processing all the '-'-options, and attempt to use those arguments as
a pid or pidlist.  If an extra argument is not a valid pidlist, then
`ps' will print an error and exit.  This seems a more generally useful
extension of the kludge-option processing than the -N/-M behavior, and
has fewer confusing side-effects.

5bd7b1f3c0 Replace pscomp() with a cleaner version, mostly written by bde (*).
This corrects a problem of lost-precision for `-r' (sort-by-CPU).  Also,
for sort-by-CPU and sort-by-memory, any processes which have the same
value CPU or MEMORY are now sorted by TTY and then (if needed) by pid.

(* - I just added the NODEV checks, after doing some testing of my own)

5dfd7724a3 If <x> is a process id that does not exist, then just print the header

lucky random value in nentries (which was not being initialized back
when I tested that earlier patch).

a4c8a745a8 Support more POSIX/SUSv3 options:
- Change `-p' to allow a list of process IDs, and `-t' to allow a list
  of terminal names, instead of only a single value for each.
- Add the `-A' option of SUSv3, which is exactly the same as `-ax'.
- Add the `-G gidlist' (group id).
- Allow any of these "selector options" to be specified multiple times,
  and have `ps' keep adding to a given list -- instead of replacing the
  previously-specified values.
- Fix interactions between selector-options, so that: "If any are
  specified, ... ps shall select the processes represented by the
  inclusive OR of all the selection-criteria options." (from SUSv3)
- Add a `-X' option, which is the reverse of the `-x' option.

- various minor improvements in parsing and error handling.

This does not get us to match POSIX/SUSv3, but it gets us closer.  The
`-g pgidlist', `-R ruserlist' and `-s sidlist' options mentioned in
freebsd-standards are still under debate, so they skipped for now.
It should be true that this introduces no user-visible incompatible
changes, except to support "new stuff" that was not supported before.
