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.)
