Windows: always display random gathering dialog when UserEnrichRandomPool is called instead of once per application run. This is implemented through the call SetRandomPoolEnrichedByUserStatus(FALSE) at the begining of sensitive operations instead of changing UserEnrichRandomPool because in the same call there can be many calls to UserEnrichRandomPool which can result in displaying the dialog many times.
