  6. romio: add MPI_Register_datarep_c 

    MPI_Register_datarep and MPI_Register_datarep_c differ in the types of
conversion function. Since we don't actually support non-NULL conversion
functions, the only difference is in the parameter types.

  7. romio: add assertions in large count functions 

    In future PR, we'll make internal count using MPI_Aint. For now, we
simply assert the values to fit in a int, and let compiler convert
MPI_Count into int.
