23ba442c88 libprocps: use float to calculate %use of slabtop
In some environments, 100 * nr_active_objs is calculated at first,
and the result of lower 32bits is divided by nr_objs. This occurs
even in a 64-bit architecture. So nr_active_objes > 42949672, %use
will be incorrect.

This fix casts type of nr_active_objs to float to calculate
correctly the %use in 32-bit/64-bit architectures.

636b48efd8 Revert "bprocps: fix order of operations for %use of slabinfo"
This reverts commit 99d71ad581.

When nr_active_objs / nr_objs is calculated, the result will be 1
or 0 since the variables are integer. So the commit is wrong.

7888f6a679 miscellaneous: clean up trailing whitespace once again
An earlier commit attempted to cleanse our environment
of all useless trailing whitespace. But the effort did
not catch 'empty' lines with a single space before ^J.

This commit hopefully finishes off the earlier effort.
In the meantime, let's pray that contributors' editors
are configured so that such wasted crap is disallowed!

fe75e26ab6 miscellaneous: clean up trailing whitespace throughout
The entire tree's polluted with inappropriate trailing
whitespace. This commit rids our environment of all of
those useless keystrokes. Unfortunately, it sure ain't
a permanent solution and requires every contributor to
instruct their editor(s) to prevent or eliminate them.

Plus it's strongly recommended we all insert something
like what's shown below to our '.gitconfig' file so as
to provide at least some warnings when we try to apply
any patches (git am) that do contain the #@!%& things!

References(s):
~/.gitconfig excerpt ---------------------------------
[core]
  whitespace = trailing-space, space-before-tab, blank-at-eof
[apply]
  whitespace = warn

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.
