caeebdc71f ps: exploit the simplified library interface for wchan
This patch was made necessary by those library changes
in support of recently revised/simplified wchan logic.

In addition, this commit eliminates a broken alternate
'namelist' provision which was intended to allow users
to specify a System.map file to be used in translating
addresses into function names. But, the real effect of
the now defunct 'N' and '-n' options was to indirectly
force addresses (not names) to be displayed since such
user named map files could not be successfully parsed.

Besides when the required FRAME_POINTER kconfig option
is absent there is no address to translate and when it
is present /proc/PID/wchan is already translated. Thus
an alternate mapping is unnecessary and inappropriate.

[ we'll forgive POSIX for documenting '-n  namelist' ]

c1c73c0d00 build-sys: merge automake subdirs into toplevel
This will be required for subdir-objects, otherwise automake will have
problems with more than one Makefile.am having rules to build the same
files.

Tested that it builds and both `make check` and `make distcheck` work.

Tested `make install` and compared the tree with the one installed
before this commit, both installed the binaries to the same locations.
The binaries are also in the same location in the build tree (for
instance, ps/pscommand is still there.)

Checked the binaries for the correct libraries linked into them. Binary
sizes matched before and after this change.

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.

c1f10d11bc Allow core file generation by ps command (rhbz#871825, rhbz#512857)
Since the ps command handles signals with it's own handler, it doesn't create
core files when something wrong happens. The attached patch restores the ps
command ability to create core files by calling the default handler once we
print our custom message. The original RH's workaround masked SIGABRT and
SIGSEGV signals and that would conflict with the original intention of the
custom signal handler and also with the filtering patch I sent in my previous
email. Moreover, this solution generates core for all relevant signals (SIGFPE,
etc.).

a65de0fd73 ps: favor truncation of long names over POSIX/UNIX standard
The UNIX and POSIX standards require that user and
group names be printed as decimal integers when there
is insufficient room.  This has led to a constant
stream of bug reports.

With this commit, long names will be truncated and
displayed with a trailing visual clue.

To avoid truncation. the UNIX and POSIX way to change
column width is to rename the column:
   ps -o pid,user=CumbersomeUserNames -o comm

The easy way is to directly specify the desired width:
   ps -o pid,user:19,comm

f4b6de1136 ps: restore missing space when environment is displayed
This commit restores the missing space between command
lines and the environment when the later is being
displayed.  Below is a brief history of that elusive
character.

commit bb4f08ba29
Date:   Thu Aug 11 07:42:14 2011 +1000
   The ps program was altered for improved args/comm
   compliance.  At this time, the needed space was
   present due to a buglet in the new library
   read_unvectored function used by fill_cmdline_cvt.

commit a5881b5a4e
Date:   Thu Dec 8 10:19:38 2011 -0600
   The trailing space was eliminated so that the
   file2strvec and fill_cmdline_cvt returned
   command lines contained no trailing space.

   However, this created a buglet when control group
   hierarchies were displayed and the final cgroup
   was empty.

   This is also where the undetected ps buglet was
   created.

commit c3a1239efe
Date:   Sun Dec 11 12:00:50 2011 -0600
   The control group anomaly was fixed but the impact
   on ps args/environ was still not detected.

a15520db8c ps abort causes problems in testsuite
Under certain circumstances, using abort() when either make check
or make distcheck puts ps into an infinite loop around the
function catastrophic_failure() in ps and the C library raise
and abort functions.

Using exit removes this problem and does almost the same thing.

2bac5334b0 ps: display the nice value for processes with the SCHED_BATCH scheduler policy
Ps command does not display the nice value for processes with the SCHED_BATCH
scheduler policy, only for SCHED_OTHER.

Boinc (http://boinc.berkeley.edu/) client runs project processing jobs on
Linux using SCHED_BATCH scheduler policy and nice value 19.  The nice value
is not displayable by ps.

Steps to Reproduce:
1. Run process using SCHED_BATCH scheduler policy with nice value.
    ./test-schedbatch 18 &
2. Display process details:
    ps -o pid,ppid,user,comm,cls,nice

Results before:
[mike@rockover c]$ ps -o pid,ppid,user,comm,cls,nice
  PID  PPID USER     COMMAND         CLS  NI
18205  2540 mike     bash             TS   0
20552 18205 mike     test-schedbatch   B   -
20553 18205 mike     ps               TS   0
[mike@rockover c]$ awk '{printf "%5d %-17s %1d %2d\n", $1, $2, $41, $19}'
/proc/20552/stat
20552 (test-schedbatch) 3 18

Results after this patch:
[mike@rockover c]$ ps -o pid,ppid,user,comm,cls,nice
  PID  PPID USER     COMMAND         CLS  NI
18205  2540 mike     bash             TS   0
20552 18205 mike     test-schedbatch   B  18
20553 18205 mike     ps               TS   0

Additional info: Here is the fragment from the sched_setscheduler(2) manual
page on the subject:

   SCHED_BATCH: Scheduling batch processes
       (Since  Linux 2.6.16.)  SCHED_BATCH can only be used at static
       priority 0.  This policy is similar to SCHED_OTHER in that it
       schedules the process according to its dynamic priority (based on the
       nice value).  The difference is that this policy will cause the
       scheduler to always assume that the process is CPU-intensive.
       Consequently, the scheduler will apply a small scheduling penalty with
       respect to wakeup behaviour, so that this process is mildly disfavored
       in scheduling decisions.

       This policy is useful for workloads that are noninteractive, but do
       not want to lower their nice value, and for workloads that want a
       determin- istic scheduling policy without interactivity causing extra
       preemptions (between the workload's tasks).

4fb48c0bdb ps: generalize help text logic, add related translator hints
This commit represents an experiment in nls help text support.

The word --help itself been made translatable along with the
help section names and their abbreviations.  Thus, the work of
the translators will ultimately alter program run-time behavior.

Perhaps someday all "long" options can behave in a similar way
which could offer a considerable benefit to other languages.
Instead of translationg just option descriptions, the long
forms of those options could also be transalated.

This commit also:
 . includes the section abbreviations in --help output
 . isolates all --help support in the ps/help.c module
 . provides (hopefully) meaningful Translator guidance
 . removes --help support from the ps/common.h header
 . removes --help support from the ps/parser.c module
 . eliminates tabs in line with the style of other ps modules
 . eliminates the need for the include/c.h header file
