Affected Issues  0025357: STL writer does not check the given shape for existing triangulation and remeshes shape using BRepMesh in force mode
Changeset 0025357: STL writer does not check the given shape for existing triangulation and remeshes shape using BRepMesh in force mode.

StlTransfer.cxx, function StlTransfer::BuildIncrementalMesh(...) fills the StlMesh_Mesh. Before this fix the StlTransfer always force meshing of the passed shape.

Now meshing is completely removed from the StlTransfer. StlWriter can return error status now, for example, if a mesh of the passed shape is empty. In this case file will be not created.

Added test case bugs/xde/bug25357

Avoid the warning on gcc compiler.
Test scripts were modified according to the fix.
     1) bug23192, bug22670, bug23193: removed "isParallel" flag from the command
         arguments. Manually meshing of the shape (as far as meshing was removed
         from STL writer).
     2) bug22898: before the fix writestl always remeshes the shape with a
         deflection, related to the boundery box of the shape. For "hammer" shape
         there is a 38.9076 deflection for mesh. Differences between before writing
         and after reading are dedicated to fact that stl writes triangulation as
         an elements of the spahe (like faces, edges etc.)
