[Mpi-22] Call for MPI 2.2 agenda items

May be we add a couple of calls to pass data back and forth between the
client and MPI? Either assertions proposed by Dick Treumann, or more
extensible (MPI_Info based?) approach proposed by Jeff Squyres? That's
admittedly connected to subsets, but this is only an addition, no
backward incompatible change. MPI 2.2?

Best regards.
