mem: Add magic field to detect memory corruption
Very little checking is performed on the validity of freelist
metadata. Add a magic field to struct arena_header which can be used
to detect memory corruption or whether a user tries to free something
that isn't a malloc pointer.
This feature can be enabled with -DDEBUG_MALLOC. Turn it on for
development in mk/devel.mk.
