    sw: fix hiding/unhiding section via condition
    
    The problem was that when un-hiding a section, table rows that contained
    only empty paragraphs were not reformatted and remained at height 0.
    
    It turns out that the table row that became visible did so because the
    cells had a VertOrientation different from NONE and so
    SwContentNotify::ImplDestroy() invalidated the cells' printarea.
    
    However, the real problem isn't in the layout code at all, as it then
    turns out that the reason why anything is reformatted at all is that
    there are docinfo fields on the same page as the section and also in the
    paragraphs at the start of the section, and these get invalidated
    somehow after unhiding the section.
    
    Unhiding the section didn't actually invalidate anything in the layout
    because in ImplSetHiddenFlag() no change is detected, and that is
    because the section was first hidden by removing its (false) condition,
    which calls SwSection::SetSectionData() and that didn't call
    ImplSetHiddenFlag(), again relying on docinfo field update to trigger
    the relayouting.

    sw: layout: fix unhiding section containing multiple page breaks
    
    With multiple page breaks in a hidden section, the following frames were
    only moved on the first break, and with the second break the frames go
    out of order in SwSectionFrame::SwClientNotify().
    
    Also handle multiple columns there.
