QElapsedTimer::elapsed returns negative values of qint64

elapsed time returns negative value of type qint64. It should return quint64. The header seems to be wrong. I noticed this bug while switching from the deprecated QTime to QElapsedTimer.

Negative value: qint64 elapsedMs = QElapsedTimer::elapsed();

Correkt value:  quint64 elapsedMs = QElapsedTimer::elapsed();

Docu:

qint64 QElapsedTimer::elapsed() const
Returns the number of milliseconds since this QElapsedTimer was last started.
Calling this function on a QElapsedTimer that is invalid results in undefined behavior.
See also start(), restart(), hasExpired(), isValid(), and invalidate().
