Instead of solely relying on the out value definitions in
MPI_Waitsome.3, explicitly copy this text here.
Note that the original text in this man page was copied verbatim from
the MPI spec; we've now added a bit more text (copied from
MPI_Waitsome.3in) that explains the out values so that users don't
have to cross-reference to another man page.
Thanks to Eric Schnetter for the suggestion.

Without this modification, gfortran throw the following error
if these variables are used for `MPI_DIST_GRAPH_CREATE_ADJACENT` or
`MPI_DIST_GRAPH_CREATE_ADJACENT`.
Error: There is no specific subroutine for the generic
'mpi_dist_graph_create_adjacent' at (1)
When using dynamic memory windows the displacement becomes a
pointer. Since the high bit may be set on valid pointers on some
platforms the check for disp > 0 is invalid. This commit adds the
window flavor to ompi_win_t and disables the displacement check when
operating on dynamic memory windows.

my RP branch had a conflict.

currently, MPI fails with MPI_ERR_ARG. This is counter intuitive since
MPI_IN_PLACE is a legitimate parameter. MPI_IN_PLACE might not be correctly
implemented by all the non blocking modules (libnbc, ...) so fail with
MPI_ERR_INTERN for the time being.
Proposed extensions for Open MPI:
- If MPI_INITLIZED is invoked and MPI is only partially initialized,
wait until MPI is fully initialized before returning.
- If MPI_FINALIZED is invoked and MPI is only partially finalized,
wait until MPI is fully finalized before returning.
- If the ompi_mpix_allow_multi_init MCA param is true, allow MPI_INIT
and MPI_INIT_THREAD to be invoked multiple times without error (MPI
will be safely initialized only the first time it is invoked).
Add ompi_mpi_dynamics_disable() function to disable MPI dynamic
process functionality (i.e., such that if MPI_COMM_SPAWN/etc. are
invoked, you'll get a show_help error explaining that MPI dynamic
process functionality is disabled in this environment -- instead of a
potentially-cryptic network or hardware error).
