This script is useful to measure times from launching ompi
application to different internal points. A user can easy add
it`s test basing on existing tests.
See readme information inside the script.
This commit removes a check that causes mca_base_group_register to
improperly create a new group instead of using an existing group
when the project and framework names are the same. This check was
originally intended to prevent forming groups with names like
ompi_ompi, opal_opal, etc but there is no reason why we shouldn't
allow that.

Mofed 2.2 does not have the IBV_EXP_QP_INIT_ATTR_ATOMICS_ARG attribute
flag. Add a check to fix compilation for mofed 2.2. This commit only
fixes complilation with the older mofed. It will not allow an Open MPI
compiled with mofed 2.3 or newer to work on a machine with mofed 2.2.

There was a bug with the way the cray pmix component
was setting the locality property for ranks on the
same node, etc.

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.
