tdf#157816 sw: PDF export: filter out links on empty space, INetAttrs

Several problems here:
* As with fields, there may be selection rectangles with no text
* SwRootFrame::CalcFrameRects() adds flys that are anchored in the
  selection to the selection
* A fly text portion causes Link annotations to split, but not Link SE
* If a fly only partially overlaps a line vertically, then
  CalcFrameRects() produces a full-width half-height rectangle and
  another 2 half-width half-height rectangles on both sides.
  This is useless, the rectangles must be full line height.
  Add some code in CalcFrameRects() to use the fly portions in the
  SwParaPortion instead of the fly frame areas.
