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.

aae3d318d4 Elf note AT_CLKTCK is only found on Linux
Suppresses a message about elf notes not found on non-Linux systems.
kFreeBSD systems, for one, don't have this so the message appears
every time you run a procps program otherwise.

a26c3bfa39 top hotplug memory support
Another patch from Jim for top to support hot-pluggable memory. Not
fully tested on real hot-pluggable memory because neither of us have
it

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.
