Return MPI1 function implementations to build list

Adding the implementations of the functions that were removed
from the MPI standard to the build list, regardless of the
state of the OMPI_ENABLE_MPI1_COMPAT.

According to the README, we want the OMPI_ENABLE_MPI1_COMPAT
configure flag to control which MPI prototypes are exposed in
mpi.h, NOT, which are built into the mpi library.  Those will
remain in the mpi library until a future major release (5.0?)

NOTE: for the Fortran implementations, we instead define
      OMPI_OMIT_MPI1_COMPAT_DECLS to 0 instead of
      OMPI_ENABLE_MPI1_COMPAT to 1.  I'm not sure why, but
      this seems to work correctly.

Also changing the removed MPI_Errhandler_create implementation
to use the non removed MPI_Comm_errhandler_function prototype
(prototype remains unchanged from MPI_Comm_errhandler_fn)
