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

8fde4af11d Call libproc constructors in strict order
Having one constructor depend on another means if the order
is reversed you get a different result.
Patched based on idea by Tom Evans.

4d3c19af52 Read the system boot time from /proc instead of computing
Read the time of system boot from /proc/stat (entry: btime) instead
of computing it as the difference between the current time and the
uptime. This is the only way to get a consistent result which won't
possibly change from one run to the next.

The problems with the original code were:
* Both the current time and the uptime are rounded down to the second,
  but the system doesn't boot on an integer second value so they do not
  tick at the same moment. Thus, the rounding errors can cause a one
  second difference from one run to the next.
* We can't read the uptime and the current time at the exact same moment
  anyway, so the time difference we compute is bound to be inaccurate.
