mem-pool: change the values to 64bits
total_allocs of certain type of variables can be 4billion in a
single day depending on load. So, 32 bits for that is not enough.
Also, size_t is good variable size for one allocation, but the
sum of allocations, should be 64bits to make sure we don't
overflow the variable.
