81f64657ba watch: exit when command output changes.
Add new flags to watch (-g/--chgexit) so that it exits when the
output changes.  This is useful in builds and shell scripts, for
example when deploying webapps to block the remainder of the
deployment steps until after the webapp starts.

e.g. watch --chgexit curl http://foo/bar

bc974b3c33 pkill: enable displaying what is killed
Add new command line options -e, --echo to display what is

because an union had to be changed to struct to allow name and
pid printing which what I as an user would expect to see in

b73a423cc2 top: avoid %cpu distortions when toggling task/thread modes
This commit addresses a long standing buglet (debian #441166) which
surfaces when the display mode is switched between task and threads.

An extra procps refresh is now forced upon such a transition which
parallels the approach used at startup for the exact same reason.

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).

3c2377ca15 Linux version for non-linux systems
On non-linux systems, uts.version provides the version of that
specific kernel (FreeBSD or Hurd version, for example) and not the
emulated procfs pseudo version.

On those systems we need to directly read /proc/version and parse the
string.  This change replaces Debian patches gnu-kbsd-version and
complain_unmounted_proc patches.
