Add missing MPI_Status conversion subroutines
Only in C bindings: - MPI_Status_c2f08() - MPI_Status_f082c() In all bindings but mpif.h - MPI_Status_f082f() - MPI_Status_f2f08() and the PMPI_* related subroutines As initially inteded by the MPI forum, the Fortran to/from Fortran 2008 conversion subtoutines are *not* implemented in the mpif.h bindings. See the discussion at mpi-forum/mpi-issues#298 Refs. open-mpi#1475 Signed-off-by: Gilles Gouaillardet <[email protected]>
