Jeff Squyres 523128100e A bunch of fixes for Fortran string issues. In general, ensure to
convert between fortran and C string representations properly.  In
doing so, we properly adhere to the MPI spec stating that MPI_Info
keys and values must be whitespace-trimmed when coming in from
Fortran.  Hence, this fixes bug #241.
