All library-specific macros for defining export / import properties of symbols on Windows (like Standard_API, __Draw_API, _math_API etc.) are eliminated. Common macro Standard_EXPORT is used in all places where it is necessary. New macro OCCT_STATIC_BUILD is defined for disabling Standard_EXPORT, to be used instead of HAVE_NO_DLL, though the latter is still supported as well (for compatibility). To allow building OCCT in static mode on Windows after these changes: - Files OSD_WNT_1.hxx and OSD_WNT_BREAK.hxx are removed; useful declarations are moved to OSD_WNT.hxx - In the class IVtkVTK_ShapeData, static fields ARRNAME_MESH_TYPES and ARRNAME_SUBSHAPE_IDS are converted to static inline functions - Global array ChoixRef defined in IntImp_ComputeTangence.cxx is converted to static function returning element of the array by index - Unused class Quantity_Convert is removed (it had static field accessed by inline method) - Struct Approx_Data defined in the same way in BRepApprox_Approx.hxx and GeomInt_WLApprox.hxx is made private member of these classes to avoid name clash - Some C++ files producing no object code are removed - In NCollection_EBTree.hxx and StdLPersistent_Collectio.hxx, definition of template virtual method is moved to class definition to avoid MSVC linker warnings on unused symbols
