    tdf#139495 doc import: prevent negative Int forced into uInt
    
    Don't cast a negative number into a sal_uInt16
    and expect good results. (ww8import test)
    
    But for bug 139495 (and ww8export3), the problem area is also
    related to pHdFormat->SetFormatAttr(SwFormatFrameSize...
    which takes an awt::Size which consists of Longs.
    So they should accept negative numbers.
    Likely the result is being treated as a uInt somewhere.
    And a negative height doesn't mean very much anyway.
    
    There seems to be a fundamental difference between
    Word and LO here. Word sets the page margins,
    but that is irrelevant to the header/footer,
    which have their own distance from the edge.
    
    In LO, the header starts at the page margin,
    and the body text must follow the header,
    (In Word, the body text can start above the header,
    as seen in the ww8export3 unit test.)
    
    [FYI: DOC format (since forever) seems to ignore the header size,
    allowing the content to at least overlap with the body text,
    but DOCX doesn't have that.
    Likely this is #112727# using floating frames hack.
    So I'd better not keep messing around in here.]

    tdf#141529 sync linked OLE save(s) with hosting file save(s)
    
    Before deactivating a linked OLE saved it and overwrote the
    original, even when not saving the hosting document at all.
    This is not intuitive from user perspective and may lead
    to unexpected data loss (of the OLE content).
    Reported case was especially about closing the hosted document
    without saving in the understandable believe that that way the
    changed OLE will not be changed on external medium.
    Added mechanism for linked OLE to hold data in a hidden local
    temp file, synching/writing back on hosting file save. Most
    complicated was adapting the 'break link' case and ensuring
    other cases to work, but looks good now from my POV

    tdf#141528 ensure that reset of linked state is executed
    
    Take m_xDocHolder->GetComponent() and xModif->setModified
    inside the local try..catch expression to ensure that the
    reset of the linked state below (m_bIsLink and .clear())
    is executed
