tdf#114441 Changing sal_uLong to appropriate integer type in filters module

   changed sal_uLong to one of {size_t, sal_uInt64, sal_uInt32, sal_uInt16, sal_uInt8} in flash/impswfdialog.cxx and graphicsfilter

   changed PS_* in file filter/source/eps/eps.cxx to enum and overloaded bitwise or (|)
   made types of nSize, nParseThis, nComp and nBytesRead to sal_uInt32 as Michael Stahl suggested

   changes suggested by Michael Stahl
   changed x, y, j to sal_uInt32 in filter/source/graphicfilter/etiff/etiff.cxx
   changed nMinPercent, nMaxPercent, nLastPercent, nMainEntitiesCount to sal_uInt16 in filter/source/graphicfilter/idxf/dxf2mtf.hxx
   removed nGcount variable from filter/source/graphicfilter/idxf/dxfgrprd.hxx and filter/source/graphicfilter/idxf/dxfgrprd.cxx
   removed static_cast in filter/source/graphicfilter/idxf/dxf2mtf.cxx
   changed nComp in filter/source/graphicfilter/ieps/ieps.cxx to size_t
   changed mnCol to sal_uInt16 in filter/source/graphicfilter/ipbm/ipbm.cxx

   revised a number of datatypes as suggested by michael stahl in his reviews

   removed redundant static casts which caused test to fail
