QHash: Improve memory-allocation strategy
Be smarter when allocating memory for the real data in
addStorage(). As the amount of entries in there follow
a binominal distribution, we know pretty well, how many
there will be at least and at most. This avoids most of
the reallocations of the storage when not rehashing, while
Tessil's tests show that the total memory consumption has
not changed.
