QHeaderView: Take padding/margin into account when eliding text

Browse Source 
When QHeaderView has an elide mode set, the available width passed to
QFontMetrics::elidedText() was not adjusted when padding or margin was
set. This lead to a too long text displayed in the header.
Now QStyle::subElementRect(SE_HeaderLabel) is used to get the correct
rect.
