fe82a3246a 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.

38763ede40 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.

c3a1239efe library: once again properly ignore a final empty cgroup
Commit a5881b5a4e, 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.

a5881b5a4e library: create cmdlines consistently with no trailing space
When PROC_FILLARG was used (invoking file2strvec)
command lines contained no trailing space.

When PROC_EDITCMDLCVT was used (invoking read_unvectored)
command lines contained a trailing space.

Now both routes to a cmdline act the same -- no trailing space.

ed59472307 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.

827334870d library: exploit enhanced library memory allocation provisions

Some were checked for failure and others were not.

7126cc4491 library: expanded/generalized memory allocation provisions
A callback provision in the form of xalloc_err_handler
(of type message_fn) was added to the alloc module.

This change allowed a program like top, who alters the
termios structure, to override the default fprint(stderr...)
behavior in the event of an error.

The new function xstrdup was also added for symmetry.

13ce6ebdf0 Use 7 cpu numbers not 4 for Hertz Hack
For the small number of devices that we cannot get Hertz out of ELF
notes but the cpu numbers make sense (ie not kFreeBSD) there is a hack
by using the CPU numbers. The problem is there was 4 numbers, now there
are 7. This fixes the hack by adding all 7 to get a more correct number.

This is from Debian patch sysinfo_7_numbers

a5750100a0 Fix Hertz calculation for FreeBSD
FreeBSD has no good way of finding the Hertz value. ELF notes don't
work, you can't find it in a function and even asm/params.h does
not have it.  Lucky for us, it is always 100.

Based upon Debian patch patch sysinfo_kfreebsd_hertz by Petr Salinger
Bug-Debian: http://bugs.debian.org/460331
Caution, 460331 has lots of overlapping bugs all around the Hertz
problem across many arches.

06d491f9e4 build-sys: take autotools in use again
This will revert change at Oct 2002 when autotools support was
removed.

Unlike before the package developers are expected to use
./autogen.sh to generate ./configure script, and run make after
that. The build system is also able to create, with make dist, a
tar ball release which compiles correctly, and has files which
seemed to be important to have.

The patch removes few unnecessary files, but no everything. Files
procps.lsm and procps.spec in git repository are useless as is,
but I left them lying around for someone who can make more
justified call about removal of them.

Last, but not least package version number is set 3.3.0 to
distinct this procps from the sourceforge's upstream procps.
Please notice that libproc relese is kept as 3.2.8.

7b0fc19e9d enhanced libproc cgroup/cmdline support, exploited by top
Library Changes
. added PROC_EDITCMDLCVT flag
. added an internal (static) fill_cmdline_cvt function:
  - reads and "escapes" /proc/#/cmdline
  - returns result as a single string in a single vector
  - callers are guaranteed a cmdline (no more NULL)
. added vectorize_this_str function, exploited by
  fill_cgroup_cvt, fill_cmdline_cvt
. generalized read_cmdline function as read_unvectored, now
  exploited by fill_cgroup_cvt, fill_cmdline_cvt, read_cmdline
  ( cgroup and cmdline no longer need be converted to string )
  ( vectors before being transformed to final representation )
. fixed bug regarding skipped group numbers (when enabled)
. escape_str made responsible for all single byte translation
  with distinction between control chars + other unprintable
. added escaped_copy function for already escaped strings
. reorganized parts of proc_t to restore formatting standards
  ( displacement changes shouldn't matter with new version # )
. former ZAP_SUSEONLY #define now OOMEM_ENABLE
. added to library.map: escaped_copy; read_cmdline

Top Program Changes
. exploited the new PROC_EDITCMDLCVT provision
. eliminated now obsolete #include "proc/escape.h"
. changed the P_WCH display format if no kernel symbol table
. fixed very old bug in lflgs for out-of-view sort fields
. former ZAP_SUSEONLY #define now OOMEM_ENABLE

Program Enhancements (top)
 . removed parse_cgroup logic in favor of libproc
 . eliminated cgroup sort recurring overhead
 . converted WCHAN field to variable width
 . generalized variable width field logic in task_show
 . real-time notation under P col more distinctive as 'rt'
Program Cosmetic (top)
 . CGROUP now known as CGROUPS (plural)
 . moved jan's attribution from top.c to 'Notes' in top.h
 . numerous comments tweaked
Document Enhancements (top)
 . documented CGROUPS field (required renumbering all fields)
 . adapted narratives for the 3 current variable width fields
 . expanded real-time scheduling notes, 'RT' now shown as 'rt'
