Fix #10444: MPI archive failure

No, I wasn't sure enough of the impact of this change to want it in 1.57.  I just merged it now, we'll have 3 months to make sure it doesn't cause any problems.  I apologize for the delay.

34c546b9cd Merge pull request #20 from aminiussi/nulltopo 
MPI_COMM_NULL is not a valid argument for MPI_Topo_test.
But it is used to indicated leftover processes when creating graph communicator or cartesians grids (for exampl, when you create a 2X2 grid from a 5 process communicator).

So we need to deal with it as a special case.

abd82f0eda Merge pull request #14 from aminiussi/compound_recv_wait 
Wait_any is missing some compound recv with intel MPI.
In practice, this change should only affect implementations which, when stacking 2 send or 2 recv will only execute the second one when the first one is completed. As a result, when testing a compound recv on compound send, we get a catch22. This merge fixes that problem.

befe62d920 The documentation at mpi-forum moved from http://www.mpi-forum.org/docs/mpi-11-html to http://www.mpi-forum.org/docs/mpi-1.1/mpi-11-html. Changed the documentation to reflect that. 
In short term, we might want to move to MPI 2.x documentation.

ed4852863a In wait_any, we need to test for compound recv of serialized object that just got the size but not the body (that is, request[1] == null & handler != null). 
Note that in:
if (current->m_requests[0] != MPI_REQUEST_NULL &&
        (current->m_requests[1] != MPI_REQUEST_NULL ||
         current->m_handler)) {
      if (optional<status> result = current->test())
        return std::make_pair(*result, current);
    }

I suspect the 3 line test should be removed and every thng handled in request::test (which is supposed to tell wheter we have a complete request).
But I have no idea why it was done like that in the first place.

463e897f75 Fix #10444: MPI archive failure 
Add "const" to save_override for archive::class_id_type and archive::version_type.  WIthout it, they do not participate in overload resolution when called with a const argument, and the default template function is called.  This leads to saving 4 bytes for archive::version_type, but only loading 1 -- all subsequent load operations are then off by 3 bytes.

fe6e8b77ac Only resize vector on root rank we're reducing to. 
As Steve Nowlen (drnuke@lanl.gov) pointed out, we can
avoid the vector resize on all ranks except the root we're
reducing to.
