Fix two problems that surfaced when using direct launch under SLURM:
1. locally store our own data because some BTLs want to retrieve
it during add_procs rather than use what they have internally
2. cleanup MPI_Abort so it correctly passes the error status all
the way down to the actual exit. When someone implemented the
"abort_peers" API, they left out the error status. So we lost
it at that point and *always* exited with a status of 1. This
forces a change to the API to include the status.

Since this header is included in .F90 files (which are preprocessed,
vs. .f90 files, which are *not* preprocessed), we don't want to
accidentally start C-style comments, which are recognized by some
Fortran compiler preprocessors (e.g., Absoft).
This commit was SVN r29394.
So just move the comment to the prior line, and it's all good. This
is obviosuly not *necessary*, but it helps cut down on warning noise.

BIND(C) doesn't let us have LOGICAL parameters, so we have to be
creative in how we invoke back-end ompi_*_f() C functions.
Additionally, the mpi_f08 type for MPI_Status presented some
difficulties, too.
See the large comment in
ompi/mpi/fortran/use-mpi-f08/mpi-f-interfaces-bind.h that explains
this in much more detail.

There is no "MPI_Aint" in the Fortran interface. Surprisingly, the
Intel compiler didn't choke on this, but the Absoft compiler did.

Remove ''some'' of the bullets from the "not on any branch" section;
there may be some others that are now eligible for removal, but I
wasn't 100% sure, so I left them.
This commit was SVN r29360.
So we now allow singletons to start on their own, only spawning an HNP when initiating an operation that actually requires it.

the fortran handle. Use a seperate opal_pointer_array to keep track of
the fortran handles of communicators.
This commit also fixes a bug in ompi_comm_idup where the newcomm was not
set until after the operation completed.

This commit was SVN r29342.
The following Trac tickets were found above:

However, tools such as mpirun don't need it, and definitely shouldn't be using it. Ditto for procs launched by mpirun.
We used to have a way of dealing with this - we had the PMI component check to see if the process was the HNP or was launched by an HNP. Sadly, moving the OPAL db framework removed
that ability as OPAL has no notion of HNPs or proc type.
So add a boolean flag to the db_base_select API that allows us to restrict selection to "local" components. This gives the PMI component the ability to reject itself as required. W
e then need to pass that param into the ess_base_std_app call so it can pass it all down.
