- Make the types of the MCA param variables be "int", not "int32_t"

- Separate out the registration of the MCA params into a standalong
  function that is invoked by ompi_mpi_init() (so that ompi_info can
  see these params)
- Rename the params to "mpi_ddt_*" instead of "datatype_*" so that
  they fit into the common naming scheme
