QHash: use the shadow seed
[ChangeLog][Important Behavior Changes] The qHash functions operating on string-like types and the qHashBits function will now mix in a shadow seed (not available in any API) if the provided main seed is not 0. This means the hashing value for any particular input has an almost zero chance of being equal in two different processes, even if processes of the same application. This unpredictability makes QHash more strongly resist denial-of-service attacks through degenerate hashing tables.
