Prevent stack overflow in the serializer/deserializer.

Prevent stack overflow in the serializer/deserializer.

We keep an eye on the recursion depth. Once it exceeds a limit, we serialize
only the object header and size, but defer serializing the object body for
after we have unwound the stack.

Michael, I uploaded the 4th patch set to fix the assertion, and to address an
issue with allocation sites.

Allocation sites need post processing (to relink them into a linked list when)
during deserialization, so we can't defer them. But since they form a linked
list, we need to be able to stop recursing, otherwise we would still run into
stack overflow if the linked list is too long. Luckily we don't have to keep the
linked list, since we are going to relink during deserialization anyways.
