Thorbjørn Martsum f633bc7f7f QHeaderView - reduce memory usage 
Though the worst case memory usage was improved in
b800d8b94a the best case usage changed.

Since best case is the same as worst case in Qt5, we should
use as little as possible, which this patch ensures.

We reduce the memory usage from 3 to 2 ints per section - which is
half of worst case in Qt4. There seems to be no bigger cost in
performance doing that. The recalcSectionStartPos is still very fast.

This patch limits the maximum section size to (2^20) ~ 1.000.000 pixels.

This alleviates
