Normally, when the chosen sort column is displayed via the
'x' command toggle the entire column is highlighted. And
while this version of top substantially reduced the cost
of such highlighting, a small pathlength increase remained.
The USE_X_COLHDR define was an experimental alternative which
eliminated all recurring runtime costs for such emphasis by
highlighting the column header, not the entire column.
The previous implementation required colors to be turned on
(the 'z' toggle) for such highlighting to be visible. This
commit extends column header emphasis to include monochrome
displays as well.

Since its inception, this top has improperly handled an
empty HOME environment variable. Under those conditions
a path to the root directory would have been constructed.
That caused no real harm upon startup since the display
defaults would have been employed. However, except for
root, it would have been impossible to save the rc file.
This commit keeps the promise made in the documentation.

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
Clean the global list of symbols contain only functions and variables which
are being called from library. The removed symbols are internal for the
library, which means they can be changed without changes to programs using
the library. This clean up should help incoming libprocps clean up work.

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.

The dejagnu tests for slabtop are skipped when "/proc/slabinfo" is
unreadable due to permissions. This commit provides the same check
for vmstat under its -m (slabinfo) option.
The man page has examples like sysctl -p filename. Optional arguments
using getopt cannot have a space between the option and argument.
So the correct format is sysctl -pfilename
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

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).

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.
procps automake defines restrict which means the binaries for procps
binaries compile. However external programs may not of defined
restrict which means they will not complie if they include files found
in /usr/include/proc.
Includes from libc6 use __restrict and if is good enough for
them, its good enough for us.
Makes Debian patch makefile_watch_ncurses redundant.
watch was being linked to NCURSES_LIBS when it should of been
WATCH_NCURSES_LIBS which can be ncursesw with 8bit enabled.
Even as conservative project as coreutils has switched to xz distributions so
neither should we have any reason to use gz and waste space & bandwidth.
