memmgmt: add support for growing memory objects

The libmemhack already knows about growing memory objects.
Now compare min. size, max. size and code addresses for growing
object configs as well. If it finds a related memory allocation,
send the new size to ugtrain as well. Even better and simpler,
always send the allocation size to ugtrain. Store it in the growing
config. The size can help us to detect out of memory object bounds
accesses.
