Restore Malloced memory counter as InUse alias + little cleanups

Browse Source 
This restores the Malloced memory counter and it's now always equal to
InUse counter.  This is only for backwards compatibility reason and
there is no separate counter.

The commit also cleanups little things like structure with a single
item (summary.inuse), and shuts up a wrong cppcheck warning (the
notorious NULL check after assignment).
