Log Message:
openmpi: updated to 4.1.6

Changes to v4.1.6 compared to v4.1.5:

- Fix configure issue with XCode 15.
- Update embedded PMIx to 3.2.5.  PMIx 3.2.5 addresses CVE-2023-41915.
  Note that prior versions of Open MPI (and their associated PMIx
  implementations) are not impacted by this CVE, because Open MPI
  never uses escalated privileges on behalf of an unprivileged user.
  We are backporting this change both because it is low risk and to
  avoid alarms from CVE scanners.
- Fix issue with buffered sends and MTL-based interfaces (Libfabric,
  PSM, Portals).
- Add missing MPI_F_STATUS_SIZE to mpi.h.  Thanks to @jprotze for
  reporting the issue.
- Update Fortran mpi module configure check to be more correct.
  Thanks to Sergey Kosukhin for identifying the issue and supplying
  the fix.
- Update to properly handle PMIx v>=4.2.3.  Thanks to Bruno Chareyre,
  Github user @sukanka, and Christof Koehler for raising the
  compatibility issues and helping test the fixes.
- Fix minor issues and add some minor performance optimizations with
  OFI support.
- Support the "striping_factor" and "striping_unit" MPI_Info \ 
names
  recomended by the MPI standard for parallel IO.
- Fixed some minor issues with UCX support.
- Minor optimization for 0-byte MPI_Alltoallw (i.e., make it a no-op).

Changes to v4.1.5 compared to v4.1.4:

- Fix crash in one-sided applications for certain process layouts.
- Update embedded OpenPMIx to version 3.2.4
- Fix issue building with ifort on MacOS.
- Backport patches to Libevent for CVE-2016-10195, CVE-2016-10196, and
  CVE-2016-10197.  Note that Open MPI's internal libevent does not
  use the impacted portions of the Libevent code base.
- SHMEM improvements:
  - Fix initializer bugs in SHMEM interface.
  - Fix unsigned type comparisons generating warnings.
  - Fix use after clear issue in shmem_ds_reset.
