This commit updates the coll/basic component to correctly order sends
and receives for cartesian communicators with cyclic boundaries. This
addresses an issue identified by mpi-forum/mpi-issues#153. This issue
occurs when the size in any dimension is 1. This gives the same
neighbor in the positive and negative directions. The old code was
sending and receiving in the same order so the -1 buffer contained
the +1 result and vise-versa. The problem is addressed by using
unique tags for each send. This should cover both the case where
overtaking is allowed and is not allowed. The former case will be
possible is a MPI_Cart_create_with_info() call is added to the
standard.

Squash compiler warning due to whitespace/brace problems.
The code block from lines 829-839 was improperly indented, which led to
both the code being confusing and a compiler warning. Comparing this code to
the current version in the MPICH repo made it clear that the code was simply
improperly indented. Fixing the indentation both makes the code readable and
squashes the compiler warning.

This change fixes the misleading error message. I added a conditional to
determine whether the error is due to a missing file or a bad interpreter.
If it is the latter, a new, more precise error message will be displayed.

This commit fixes a segfault in mtl-portals4 finalize(). The segfault
occurs if finalize() is called without any calls to add_procs(). This
commit resolves the segfault by skipping the flow control fini() call if
Portals4 was not initialized.

1) Race condition: Do not add private contexts to active list.
Private contexts are only visible to the user.
2) Recycled contexts: Destroyed contexts are put on an idle list until
finalize, continuous context creation will lead to oom condition.
Instead, check if context from idle list meets new context requirements
and reuse it.

in schizo/ompi, sets the new OMPI_MCA_mpi_oversubscribe environment
variable according to the node oversubscription state.
This MCA parameter is used to set the default value of the
mpi_yield_when_idle parameter.
This two steps tango is needed so the mpi_yield_when_idle setting
is always honored when set in a config file.

This is based on a bug reported on the mailing list using a netcdf testcase.
The problem occurs if processes are using a custom file view, but on some
of them it appears as if the default file view is being used. Because of that,
the simple-grouping option lead to different number of aggregators used on different
processes, and ultimately to a deadlock. This patch fixes the problem by not using
the file_view size anymore for the calculation in the simple-grouping option,
but the contiguous chunk size (which is identical on all processes).

In order to work around an issue with flang based compilers,
avoid declaring bind(C) constants and use plain Fortran parameter
instead.
For example,
type(MPI_Comm), bind(C, name="ompi_f08_mpi_comm_world") OMPI_PROTECTED :: MPI_COMM_WORLD
is changed to
type(MPI_Comm), parameter :: MPI_COMM_WORLD = MPI_Comm(OMPI_MPI_COMM_WORLD)
Note that in order to preserve ABI compatibility, ompi/mpi/fortran/use-mpi-f08/constants.{c,h}
have been kept even if its symbols are no more referenced by Open MPI.
