ps: add build option to disable ps option warning
Slackware seems to have this patch, while it is not in use(?) Well,
the upstream procps-ng allows one to disable warnings if that is
wanted. After all having this sort of 'feature' does not cost much,
while lacking it might annoy someone.
A patch from Slackware.

Rename library and use proper versioning
Previously the version of libproc always tracked the version of procps.
This doesn't work when other non-procps programs link to the library as
they are always playing catch up.
This change makes the library version independent of the procps version.
It will only be incremented when needed.

library: once again properly ignore a final empty cgroup
Commit a5881b5a4e5056d13906ce6128f6aa180d67d60e, addressing
command lines with a trailing space, produced an undesirable
side effect in the fill_cgroup_cvt() function.
This patch restores correct cgroup behavior while still
producing command lines with no trailing space.
The code -----------------------
if (P_MAXPFLGS < f) { w->endpflg = i; continue; }
The background -----------------
The enum P_MAXPFLGS is strictly a fencepost and can *never* appear in
the arrays pflgsall or procflgs. Thus it (39th element) cannot be used
in referencing Fieldstab.
However, two enums of higher value (X_XON=40 and X_XOF=41) *can* appear
in those arrays. But the test against the fencepost ensures that those
two enums are *never* used in referencing Fieldstab.
When the analyzer sees the conditional using '<' and not '<='
it reports a false positive.
The source was changed to accommodate the tool's deficiency

top: forest view segmentation fault, the final solution
With forest view mode under procps-ng-3.3.0, top would catch
a SEGV and exit. The problem was thought to be related to
some linux version 3 anamoly.
In procps-ng-3.3.1, top was protected from abnormal exit and
would display the offending processes with the special orphan
notation '?', instead of the usual artwork.
As it turns out, the problem wasn't with linux and could
surface under a 2.6.xx kernel, The cause was an occasional
abnormal ordering of tid/tgid/ppid which went unresolved
due to a progressive proc table scan in the recursive
function forest_add().
By default the proc table scan now restarts at the beginning.
However, a #define TREE_ONEPASS is provided should one wish
to restore the 3.3.1 behavior with its reduced overhead.

top: correct an obscure column highlighting buglet
An anomaly would surface whenever the sort column was
made non-display under fields management.
The scroll message would report incorrect x coordinates
and the 'x' toggle would produce an unintentional
horizontal scroll.
This patch forces column highlighting off whenever field
changes are made (as is done for horizontal scrolling).
It also inactivates the 'x' toggle whenever the sort
column is not visible.

library: provide for huge cmdlines, like old libproc
The CodingStyle document suggests programs should allow for
cmdlines of at least 128k. Only the ps program can display
such a cmdline, and only with multiple -w switches.
The library function file2strvec can essentially return
a cmdline of unlimited length. However, the library function
fill_cmdline_cvt used an arbitrary upper limit of 2048 for
buffers automatically allocated on the stack.
This patch raises the fill_cmdline_cvt upper limit to 128k via
dymaically acquired utility buffers ensured by the openproc
function.
It also makes indentation consistent in the openproc function.

slabtop check has optional spaces at start of line
There is a race condition between expect script consuming the output
from slabtop. There were a sequences of lines that looked like

with the last \s* consuming the first space on the start of the line.
However if the line takes too long to print, then expect stops there and
the space at the start of the subsquent line does not match.
