MPI-4 is finally cleaning up its language: an MPI "exception" does not actually exist. The only thing that exists is an MPI "error" (and associated handlers). This commit replaces all relevant uses of the word "exception" with "error". Note that this is still applicable in versions of the MPI standard less than MPI-4.0 (indeed, nearly all the cases fixed in this commit are just changes to comments, anyway). One exception to this is the Java bindings, where there's an MPIException class. In hindsight, it probably should have been named MPIError, but changing it now would break anyone who is using the Java bindings. Signed-off-by: Jeff Squyres <jsquyres@cisco.com>
