This commit just tweaks top in the following respects:

. for alphabetic integrity, change 'INSP_hdr...' names

. eliminate the -Wsometimes-uninitialized warning that
was found under OSX Yosemite (llvm 6.0/clang-600.0.56)

f8e98b65ae free: Use IEC units
Free always used 1024 based units but used the confusing old style
kilo,mega etc.

This change changes the names to kibi,mebi for 1024 based divisors
and kilo,mega for 1000 based divisors or IEC units.

It also checks if you try to set two units, e.g free -k -m
Petabyte and Pebibyte have been added.

If you used to use the long options such as --mega these will now
actually print megabytes (they previously printed mebibytes).
The short options are being used on the IEC units

6ed8cf3444 pgrep: Off by one in realloc in option handling
The loop that parses options has a of by one bug where the realloc
adds one byte, instead of one list element.  This is exposed when
you try things like:
  pgrep -t,,,,

fd77ca1dc6 pgrep.1 removed STANDARDS section
pgrep got updated due to the confusion of the f,l and a flags.
While the newer behaviour is far better but it is no longer following
the ancient Solaris standards, so that got removed.

f71405b44d w: fixing missing '-' in the FROM field when empty
With 99bebff06a a configurable
width of the FROM column was introduced. Unfortunately this
caused a regression in the dash printing. Hopefully fixed

92071e963e pmap: print process even if smaps unreadable
pmap would previously print the process name if
/proc/PID/smaps could be opened, even if subsequent
reads failed.  This actually occurs with other users
PIDs.

Kernel 3.18rc1 introduced a change where the file could
not been opened, meaning pmap -X 1 previously showed
the process name and nothing else but NOW shows nothing
make check failed because of this.

This change prints the process name even before trying to open
the file, returning it to previous behaviour.
Thanks to Vincent Bernat for some analysis.

7610b3128e skill: fix command line with signal
If skill was used with a signal number then it would intepret
the command line with last option interpreted twice. This often
confused the program so it just would end up killing nothing.
So this would work:
skill -t pts/0
This would not:
skill -9 -t pts/0

The kill path (in the same file) uses the same logic that has
been introduced here.

da06b8fa59 top: tweak forest view protections for forking anomaly
A recent commit eliminated the potential for a storage
violation with forest view mode. It occurred when some
program (erroneously?) created a lengthy forking loop.
However, the associated commit message was misleading.

The message implied that an unexpected order following
a sort on start_time was the cause of storage overruns
and a 'char' used to track nesting level only distorts
the display when it goes negative. Actually, the truth
is really just the opposite. Any start_time sort quirk
causes no harm while that 'char' can yield corruption.

Should some child end up sorted ahead of its parent by
way of an extremely unlikely shared start_time the end
result is such a child will be displayed unnested just
like init or kthreadd along with all its own children.

However, if nesting levels exceeded 255 (and became 0)
a massive array overrun could be triggered when such a
task and *all* its children were added to an array for
the second time. Exactly how much storage was violated
depended on the number of children that zeroed process
had spawned (hinted at via either SIGSEGV or SIGABRT).

The earlier commit limited nested levels to 100 so the
root cause of the storage violation was already fixed.
The potential for distorted nesting levels due to sort
on start_time would seem to remain. But it's extremely
unlikely that 2 tasks would share the same start_time.

Even so, a new #define has been introduced which makes
top impervious to the order of tasks such that a qsort
is no longer necessary (providing an init/systemd task
exists & was harvested as the first task by readproc).
It can be utilized if distorted nesting ever becomes a
real issue. But since there is a 5-10% performance hit
with that, we'll continue using start_time as default.

ce70017eb1 top: provide some protection against forking anomalies
This commit will eliminate a very nasty bug associated
with top's forest view mode.  It addresses a potential
SIGSEGV/SIGABRT that was only encountered when another
program (erroneously?) creates a lengthy forking loop.

If the growing list of nested children is sufficiently
fast such that proc_t start_time is duplicated between
children then the sort upon which top relies might not
produce the expected order. That, in turn, could cause
the forest_adds function to initially miss some child.

But that missed child would be caught by forest_create
and eventually would cause our array boundary overrun.
Such overrun occurs when some child of that originally
*missed* child is found and a duplicate add attempted.

In correcting this bug we'll also use this opportunity
to prohibit a borrowed proc_t padding byte (char) from
going negative. If the nesting level exceeded 127, the
effect was an "unnesting" with the snprintf width then
viewed as flag+width also yielding left justification.

Henceforth, we'll limit nesting to 100 with subsequent
children shown as " +  ", not the usual " `- " prefix.

b0767bd391 top: ensure previously saved rcfile honored completely
When startup defaults were changed users with existing
rcfiles would likely find their previous configuration
was not being honored in all respects. The disparities
involved Graphs modes and Summary/Task memory scaling.

This patch simply restores what was always intended as
the proper behavior for previously saved config files.

2f975ba49d tload: fix lockup
It looks like an off by one error was added to tload a couple years
ago while removing goto statements.  This causes tload to go into
an endless loop when the load is just under a scale change integer.
eg: .99, 1.99, 3.99, 7.99

to reproduce you can add, just under the loadavg at line 170 in tload.c:
av[0] = 1.99;

or get the load to that level separately.

The patch below makes the code more like the original, but without the
goto statements.  This can also be fixed by just changing line 183 in
tload.c from "if (0 < row)" -> "if (0 <= row)".
