Fixed mismatches cell arrays in vtkPStreamTracer.

vtkPStreamTracer was not consistently generating cell arrays on all ranks. The
ReasonForTermination array was missing on occasion. This was causing segfaults
when rendering translucent streamlines in ParaView since several pipelines
assume that data arrays match across all processes. This fixes that issue. We
were missing adding of the ReasonForTermination for the exception case where the
integration resulted in a single point streamline.

Report an error when writing a file with changing topology.

If the number of points, cells or blocks change from one time step to the next,
report an error. We modified the writer to suport temporal files with
changing topology, however the reader does not yet supports it.
