Brian Barrett 8f68764e5e A number of heterogeneous fixes for the dss with the new buffer options: 
* When using the load/unload interface, stash away the current buffer
    type so that it can be properly unpacked on the receiving side if
    the buffer type is other than the receiver default
  * Include type information for unsized types (bool, int, size_t,
    pid_t) so that they can be properly unpacked by the receiver
    in the heterogeneous case.
  * Restore the NON_DESC type as the default for optimized builds,
    since it looks like this fixes the known issues with the
    non-described buffers
