Avoid overflow when computing remainders from QRoundingDown::qDiv()
For a value in the partial interval just before the type's minimum,
multiplying the qDiv() result back up by the factor overflows; so take
care to adjust the values away from the bound. Introduce qDivMod() to
take care of that; in due course, we can also use it where both
quotient and remainder are wanted.
