similar to what ompi_convertor_unpack does. This is the solution for
the test case attached to ticket #690.

Fix trac #737, #738. Reviewed by jsquyres.
* A couple of cxx tests in ompi-tests (winkeyval.cc & typekeyval.cc)
will be re-enabled to regression test for this fix.

The OMPI_HAVE_ATTRIBUTE flag is always set when the oldest attribute
is supported. But in all cases when the OMPI_HAVE_ATTRIBUTE is set and
one of the attributes is not supported the empty declaration is missing.

Tested this functionality quite a bit more and made some fixes:
* Print far fewer help messages
* Fix one additional deadlock upon error
* Change some ORTE_LOG messages to silent (because they're not
errors)
* Some code got re-indented, sorry...
Discussed and reviewed with Ralph.

yesterday and set it to "true" in orte_init(). But ompi_mpi_init()
doesn't call orte_init() -- it calls orte_init_stage1() and
orte_init_stage2(). So orte_initialized was never set to true, and
Badness happend from there (w.r.t. ompi_mpi_abort()).
This patch moves the setting of orte_initialized to orte_init_stage2()
so that everyone will always get it set properly.
It also moves setting orte_universe_info.state to RUNNING into
stage2() as well -- Ralph confirmed that that should have been there
for the same reasons that orte_initialized needs to be there.

- optimization (pure, const, malloc--restrictness)
- data layout (packed)
- interface definition, API (deprecated, visibility, weak alias)
- compiler hint for code analysis and debugging (nonnull, format)

completed successfully, Bad Things(tm) could happen.
* Now we explicitly check orte_initialized (a new global in ORTE
indicating whether we are between orte_init() and orte_finalize()
or not), and if so, react accordingly.
* If ORTE is initialized, use orte_system_info.nodename; otherwise,
use gethostname().
* Add loop protection to ensure that ompi_mpi_abort() is not invoked
multiple times recursively.

know what my local rank is, and therefore set my paffinity ID as
appropriate. Specifically, we're no longer relying on the
special/secret mpi_paffinity_processor MCA parameter that the orted
would set for us.
This allows processor affinity to be used in environments where the
orted is not used (e.g., bproc, and someday in the hopefully not
too-distant future, SLURM).

Over to Jeff now for modifying mpi_init accordingly.
Until Jeff makes his changes, nobody should see anything different as the new info just isn't used by anything!

MPICH2 for "small" commutative operations in the reduce_scatter basic
implementation. "small" is currently pretty big, as it doesn't take
much to beat reduce/scatterv. Need to do much more than this for
better all around performance of MPI_Reduce_scatter, but this was enough
to solve the problems I was having.

Found another places that we were incorrectly casting a C++ MPI handle
array to the corresponding C array type and hoping for the best (which
won't work at all). This commit fixes things so that we now do the
proper conversion between C<-->C++ handles.

having a regular, recognizeable, repeatable value is probably much
better for debugging purposes.

and George on these refinements):
* Rename the static OBJ initializer macro to be
OPAL_OBJ_STATIC_INIT(class)
* Ensure that all static OBJ initializations get a refcount of 1
(doesn't ''really'' matter, since they're static, it should never
get to the point where the OBJ is DESTRUCTed, but more correct
nonetheless)
* Add a "magic number" to the OBJ when compiling with debug support.
The magic number does some rudimentary support to ensure that
you're operating on a valid OBJ (and fails an assertion if you're
not). Check to ensure that the memory contains the magic number
when performing actions of OBJ's. Also remove the magic number
when DESTRUCTing OBJs, so that if, for example, an OBJ is
DESTRUCTed more than once, we'll fail the magic number assert.

I did not see any performance difference over MX up to 64 nodes, but
the change makes sense and may have some impact when we have (many)
more nodes.
