Cray has added plugins to slurm to support
the Cray programming env (alpslli, cray pmi, etc).
Some of the workarounds needed with plm/alps
to avoid issues with Cray PMI getting mixed up
with orte launch system are also required in
a cray native slurm environment.

There was a bug with the way the cray pmix component
was setting the locality property for ranks on the
same node, etc.
Improve location/syntax of a comment block.

If btl-portals4 is configured to use logical mapping of ranks to
physical nodes, then the endpoint must have the rank field set.
This commit fixes a bug that caused the endpoint to have the
nid/pid instead of the rank if the endpoint already exists.
`MPI_WIN_TEST` must update the `flag` parameter to 0 when not all
origin processes called `MPI_WIN_COMPLETE`. But sm OSC doesn't.
If the caller initialize the `flag` argument to a non-0 value,
the caller will receive the non-0 `flag` value.
Previous commit f2794740 reverts Nathans changes. However it turns out
that I was unable to trace his logic until I started investigation of
icsplit hang. Bug was triggered when splitting Intercom was giving a group
where on side of the communicator was empty (icsplit, intercom create #2).
in this case remote_size == 0 and there is no way to distinguish between
inter- and intra-communicator.
Conclusion: We do need to distinguish between intra- and inter-communicators.
So we should use ompi_mpi_group_null.group.
This commit adds a call to ompi_request_wait_completion for buffered
sends. Without this line it is possible to get into a state where the
data is never sent.

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.
Fixesopen-mpi/ompi#1153
some of the collective modules. Added a new function
opan_datatype_span, to compute the memory span of
count number of datatype, excluding the gaps in the
beginning and at the end. If a memory allocation is
made using the returned value, the gap (also returned)
should be removed from the allocated pointer.
