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 commit DELETES the removed MPI1 functions and datatypes from
both the mpi.h header and from the library (they were deleted from the
MPI standard in MPI-3.0).
WARNING: This changes the MPI API in a non-backwards compatible way.
This also removes the configure option that was added in Open
MPI v4.0.x, requiring users to change their apps if they are
using any of these almost 20 year old APIs.
This commit removes the following MPI1 removed functions and datatypes:
MPI_Address
MPI_Errhandler_create
MPI_Errhandler_get
MPI_Errhandler_set
MPI_Type_extent
MPI_Type_hindexed
MPI_Type_hvector
MPI_Type_struct
MPI_Type_UB
MPI_Type_LB

This commit is intended to be cherry-picked to v4.0.x and
the following commit will ammend to this functionality for
master's removal.
Changes the prototypes for MPI removed functions in the
following ways:
There are 4 cases:
1) User wants MPI-1 compatibility (--enable-mpi1-compatibility)
MPI_Address (and friends) are declared in mpi.h with
deprecation notice
2) User does not want MPI-1 compatibility, and has a C11-capable
compiler
Declare an MPI_Address (etc.) macro in mpi.h, which will
cause a compile-time error using _Static_assert C11 feature
3) User does not want MPI-1 compatibility, and does not have a
C11-capable compiler, but the compiler supports error function
attributes.
Declare an MPI_Address (etc.) macro in mpi.h, which will
cause a compile-time error using error function attribute.
4) User does not want MPI-1 compatibility, and does not have a
C11-capable compiler, or a compiler that supports error
function attributes.
Do not declare MPI_Address (etc.) in mpi.h at all.
Unless the user is compiling with something like -Werror,
this will allow the user's code to compile. We are
choosing this because it seems like a losing battle to
make some kind of compile time error that is friendly to
the user (and doesn't make it look like mpi.h itself is broken).
On v4.0.x, this will allow the user code to both compile
(albeit with a warning) and link (because the MPI_Address
will be in the MPI library because we are preserving ABI
back to 3.0.x).
On master/v5.0.x, this will allow the user code to compile,
but it will fail to link (because the MPI_Address symbol will
not be in the MPI library).

Ensure we publish all the info required to be returned to the other
mpirun when executing this operation. We need to know the daemon (and
its URI) that is hosting each of the other procs so we can do a direct
modex operation and retrieve their connection info.

When Slurm is built against PMIx, some installations place a copy of the
PMIx library that Slurm is linking against in the Slurm PMI location.
Current configury ignores that location. The desired behavior is to look
for a PMIx lib in that location when --with-pmi is given. If the user
also specifies --with-pmix and gives a different location, then override
anything previously found and look for it where the user directed.

commit c6070fd2e broke building fortran bindings
with PGI compilers. Turns out PGI compilers need
to link in the *.o from a module file whether or
not there are module subroutines defined or not in
the module file.

mark the "self" peer OMPI_OSC_RDMA_PEER_LOCAL_BASE when
the window is dynamically created and use_cpu_atomics is set
in order to correctly handle communications to self.
Thanks Bart Janssens for reporting this issue.
