This commit adds a new configure option: --enable-mpi1-compat. Without this option we will no longer provide APIs, typedefs, and defines that were removed from the standard in MPI-3.0. This option will exist for one major release (Open MPI v4.x.x) and then the option and associated code will be removed in Open MPI v5.x.x. Open MPI has already internally prepared for this change. Please prepare your codes accordingly. Signed-off-by: Nathan Hjelm <hjelmn@lanl.gov>
