Especially its "next" member: this is what caused the crash in "slabtop:
Reset slab_list if get_slabinfo() fails." (if parse_slabinfo*() fails in
sscanf(), for example, then curr is set to NULL but it is already linked
into the "list" and its "next" member was never initialized).
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.

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.
In some environments, 100 * nr_active_objs is calculated at first,
and lower 32bit of the result is divided by nr_objs.
If 100 * nr_active_objs > 42949672, %use will be incorrect.

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!

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!

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.
