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
There were numerous library memory allocation inconsistencies.
Some were checked for failure and others were not.

All library source modules were modified to utilize the alloc.h
memory rouines which are consistent in dealing with errors.

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

Ps Program Changes
. exploited the new PROC_EDITCMDLCVT provision
. exploited the new escaped_copy function
. consolidated pr_args and pr_comm into pr_argcom

57031319d6 cgroup support migrated to libproc, plus miscellaneous re-formatting
This source patchset addresses the following:
Library Extension (readproc)
 . added PROC_EDITCGRPCVT flag
 . added an internal (static) fill_cgroup_cvt function:
   . reads AND parses /proc/#/cgroup
   . returns result as a single string in a single vector
   . thus no changes to proc_t structure or free memory logic
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'
