91df65b9e7 docs: Document I idle state in ps and top
Linux 4.2 provided a new process state of I which is used for an idle
kernel thread. This new state means that kernel threads do not
contribute to the loadavg as they are no longer state D or S but I.

While both ps and top displayed this state, it wasn't documented in
either manual page until now.

66c4024d75 ps: respond to loss of that PIDS_WCHAN_ADDR enumerator
No longer will ps print nwchan as 'ffffff', '-' or '1'
since the proc/PID/stat wchan field didn't represent a
real address anyway. Rather, the field will henceforth
output a dash ('-'), the ps customary 'not available'.

That man document was also tweaked to better represent
actual behavior. An asterisk ('*') was never shown for
threaded tasks and that dash ('-') usually didn't mean
running tasks (sometimes associated with permissions).

03b148d517 ps: display control group name
The cgroup field while shown as a vector is a concatenated
string, so alot of the complexity of sorting and displaying
has gone.

This change simplifies the cgroup sorting and adds display
and sorting for the name attribute of the cgroup, if found.

e751606fcc ps: add -q/q/--quick-pid option
This commit introduces a new option q/-q/--quick-pid
to the 'ps' command. The option does a similar job
to the p/-p/--pid option (i.e. selection of PIDs
listed in the comma separated list that follows
the option), but the new option is optimized
for speed.
In cases where users only need to specify a list
of PIDs to be shown and don't need other selection
options, forest type output and sorting options,
the new option is recommended as it decreases
the initial processing delay by avoiding reading
the necessary information from all the processes
running on the system and by simplifying
the internal filtering logic.

fe75e26ab6 miscellaneous: clean up trailing whitespace throughout
The entire tree's polluted with inappropriate trailing
whitespace. This commit rids our environment of all of
those useless keystrokes. Unfortunately, it sure ain't
a permanent solution and requires every contributor to
instruct their editor(s) to prevent or eliminate them.

Plus it's strongly recommended we all insert something
like what's shown below to our '.gitconfig' file so as
to provide at least some warnings when we try to apply
any patches (git am) that do contain the #@!%& things!

dc1531b211 Removed bogus bogus -aux message
This message has been here for ages and either people ignore it because
they are so used to using -aux or never see it.  It was here before 2005
and really 7 years is enought time to people to change their ways.

The notice is now removed, people who make usenames like "x" deserve all
the punishment they can get.
