[OMPI devel] Missing error strings for MPI_ERR_RMA_XXX error classes

[Lisandro Dalcin]

I'm testing openmpi-1.8.

MPI_Get_error_string() for the following error classes is failing. I
guess you just forgot to update the list of error strings.

    MPI_ERR_RMA_RANGE
    MPI_ERR_RMA_ATTACH
    MPI_ERR_RMA_FLAVOR
    MPI_ERR_RMA_SHARED

I'm attaching a simple test code for you to verify the issue.

Additionally, please update the following comment in mpi.h

/* Per MPI-3 p349 47, MPI_ERR_LASTCODE must be >= the last predefined
   MPI_ERR_<foo> code.  So just set it equal to the last code --
   MPI_ERR_RMA_FLAVOR, in this case. */
#define MPI_ERR_LASTCODE              MPI_ERR_RMA_SHARED

The comment is wrong, the last predefined error class is
MPI_ERR_RMA_SHARED and not  MPI_ERR_RMA_FLAVOR.
