The procedure names don't contain "_f08" of Fortran 2008 bindings of
Persistent Collective Operations(mpiext/pcollreq/use-mpi-f08).
This fix adds "_f08" to the procedure names of pcollreq/use-mpi-f08,
same as other Fortran 2008 routines in `ompi/mpi/fortran/use-mpi-f08/mod`.

This commit fixes an issue seem with some older versions of gcc
(verified to occur in gcc 6.x) where on x86_64 systems the
acquire memory barrier in C11 atomics acts as a no-op. On these
systems the three memory barriers should all be equivalent.
This is related to the error fixed in open-mpi/ompi@30119ee.

Use the PVAR ctx to save the SPC index, so that no lookup nor
restriction on the SPC vars position is imposed.
Make sure the PVAR are always registered.

this commmit fixes coverty warnings CID 1445198 and CID 1445197
For a reason that is a bit unclear to me, coverty only complained about the read
files, but the write operations had the same issue, so I fixed that within the
same commit as well.

Java bindings in Open MPI support Java arrays and direct buffers
as buffers. All non-blocking methods must use direct buffers and
only blocking methods can choose between Java arrays and
direct buffers.
Though Comm.allToAllw() is a blocking method, Java applications
using Java arrays as buffers get compilation errors.
This fix enables using Java arrays in Comm.allToAllw().

external32 data representation is now support by ompio for everything
but non-blocking collective I/O operations. The support can further be improved
in a second step to limit the temporary buffer size (at least for blocking operations),
but it does work now for many scenarios.

introduce separate convertors for memory vs. file representation. Adjust the interfaces for decode_datatype to provide the convertor to be used for that.

the infrastructure put in place to manage cuda buffers is actually
a lot more generic than just for cuda buffers. Specifically, we ca
reuse much of the code to implement the external32 data representation.
This commit converts the code from common_ompio_cuda* to
common_ompio_buffer*. There are just very few places where we actually need to keep the OPAL_CUDA_SUPPORT ifdef in place.

Atomic lock must progress local worker while obtaining the remote lock,
otherwise an active message which actually releases the lock might not
be processed while polling on local memory location.

SLURM 19 discontinued the use of --cpu_bind (and changed it to
--cpu-bind). There's no easy way to test at run time which one is
accepted, so set the environment variable SLURM_CPU_BIND to "none",
which should do the same thing as the srun CLI parameter.
