Fixed size calculation bug in manager_size_overhead.
If there were extra refs to some cache mapping on the stack (e.g. when
called via low_add_entry), it didn't include that mapping in the size.
Also, together with an as yet future optimization in
Pike.count_memory, this avoids a running time in manager_size_overhead
(and hence update_size_limit) that is linear wrt the cache size.
