Makes page rendering in splash thread safe

Here now the patch which makes page rendering thread safe. It especially offers
a new parameter fMT (multi thread) for PDFDoc::displayPageSlice which must be
set to gTrue if it should use in different threads with a shared PDFDoc object.
Only splash is really thread safe with this patch, because I haven't time to
test other output devices (and therefore didn't made the necessary changes
there). But it should be quite easy to make also other devices thread safe now:
just assure that nowhere the doc->getXRef() is used, use the new parameter
given by startPage.
