Nathan Hjelm 0b8fc13299 MPI-3.0: update C bindings with const and consistent use of [] for
arrays.

The MPI 3.0 standard added const to all in buffers in the C bindings. This
commit adds the const keyword and in most cases casts const away. We will
eventually should go through and update the various interfaces (coll, pml,
io, etc) to take the const keyword. The group, comm, win, and datatype
interfaces have been updated with const.
