Replace QAbstractItemView::viewOptions with initViewItemOption

Browse Source 
viewOptions returned a QStyleOptionViewItem object. Such a method
can never support newer versions of the option structure.

Most styleable QWidget classes provide a virtual method
initStyleOption that initializes the option object passed in as a
pointer, e.g QFrame, QAbstractSpinBox, or QComboBox.

Follow that API convention, but name it initViewItemOption, as the
QStyleOptionViewItem struct contains information about the item as
well as the widget itelf.

This is a source incompatible change that will go unnoticed unless
existing subclasses mark their overrides as 'override', or call
the removed QAbstractItemView::viewOption virtual function.

[ChangeLog][QtWidgets][QAbstractItemView] The virtual viewOptions
method that previously returned a QStyleOptionViewItem object has
been renamed to initViewItemOption, and initializes a
QStyleOptionViewItem object that's passed in through a pointer.
