Adapt Visit CGNS file reader to use CGNS 3.x
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
The changes required to the CGNS reader to support CGNS 3.x are very small. For 32-bit builds there is no need to change anything as cgsize_t maps to int on 32-bit platform. For 64-bit builds the cgsize_t type needs to replace int at a couple of places. After that it works.
See the attached diffs that were made with the 3.10.1 source tree. I'll send the diffs to VisIt too, but beware that on avtCGNSFileFormat.C:1077 there is a difference between the VisIt source code and the ParaView source due to a bug in the VisIt code that was fixed in ParaView (see also http://public.kitware.com/pipermail/paraview/2011-March/020562.html)
