Another patch from Jim for top to support hot-pluggable memory. Not

it

c2dcbef482 added output width/height override support to top, + misc
This source patch addresses the following:
 Enhancements
  . added -w command line switch, with optional argument
   ( offers complete control over width and height, in  )
   ( combination with env variables COLUMNS= and LINES= )
  . updated man document to reflect the new capability
  . reengineered Fields Management to be more flexible
    thus no longer requiring a normal sized tty
 Buglets fixed
  . forced View_SCROLL off when in 'Batch' mode
  . for narrow xterm, fixed return val in show_pmt
  . for narrow xterm, fixed cursor pos in linein
  . added a window specific end-of-line termcap ptr
   ( so clr_eol does not overwrite last printable char )
 Cosmetic changes
  . eliminated TTYGETENVYES define, incorporated as -w
  . eliminated RESIZE_LIMIT define, no longer needed
  . eliminated FIELD_CURSOR define, no longer possible
  . eliminated extra text on Fields Management screen
  . fixed miscellaneous man document typos/formatting

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

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

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'

 . 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'
