DEBUG/MEDIUM: memory: optionally protect free data in pools

When debugging a core file, it's sometimes convenient to be able to
visit the released entries in the pools (typically last released
session). Unfortunately the first bytes of these entries are destroyed
by the link elements of the pool. And of course, most structures have
their most accessed elements at the beginning of the structure (typically
flags). Let's add a build-time option DEBUG_MEMORY_POOLS which allocates
an extra pointer in each pool to put the link at the end of each pool
item instead of the beginning.
