Giuseppe D'Angelo 19072a177b QPageLayout: do not calculate an invalid margin 
A default constructed QPageLayout has an invalid QPageSize. When
asking for its size, an invalid QSize is returned (-1, -1). This
size is then used to calculate the maximum margins the page layout
can have, resulting in negative margins.

I'm not sure if that makes sense for QPageLayout (in principle, a
negative margin is acceptable, meaning to "grow" the size), but then
this margin is passed as an upper bound to a series of qBound calls in
QPageLayoutPrivate::clampMargins.

To fix this, change the calculations of the maximum margins by using
a lower bound of 0.
