Painting borders of Flys in the heaven layer cannot be done correctly in
SwRootFrm::Paint, because delaying until then paints over other drawing
objects that are on top of the frame, so do it in SwFlyFrm::Paint,
like the old border painting code used to.

Remove macro RTL_CONSTASCII_USTRINGPARAM in starmath (partial)

This reverts commit 568d3912.

HTMLParser::IsHTMLFormat() is convinced that anything containing a valid HTML
tag would indeed be HTML, which is a rather idiotic assumption for us in the
case of "foo <br> bar" with a preselected CSV filter. So keep this detection to

The original order where preselected CSV had precedence over others was changed
with 9f1cc58c

Creating an SotStorage with a 0-length stream has the side-effect of creating
the compound document (aka OLE storage) header on the stream and effectively
writing that to disk, thus garbling the empty file.

Otherwise exception throwing seems to be broken.
This is a partial revert of b0515ea5.
