When allocating memory, zero out them if we don't intend to overwrite them
all; before freeing memory, zero out them before we release it as free
heap.  This will eliminate some potential information leak issue.

While there, remove the PURIFY option.  There is a slight difference between
the new behavior and the old -DPURIFY behavior, with the latter initializes
memory with 0xff's.  The difference between old and new approach does not
generate observable difference.
