Consolidate the ompi_process_info and opal_process_info structs to
remove duplicate storage and conversion issues. Unwind some interweaving
of include files using opal.h. Silence a couple of warnings.
For now, set the arch to local if PMIX_ARCH is not found.

Add a framework to support different types of threading models including
user space thread packages such as Qthreads and argobot:
https://github.com/pmodels/argobotshttps://github.com/Qthreads/qthreads
The default threading model is pthreads. Alternate thread models are
specificed at configure time using the --with-threads=X option.
The framework is static. The theading model to use is selected at
Open MPI configure/build time.
mca/threads: implement Argobots threading layer
config: fix thread configury
- Add double quotations
- Change Argobot to Argobots
config: implement Argobots check
If the poll time is too long, MPI hangs.
This quick fix just sets it to 0, but it is not good for the
Pthreads version. Need to find a good way to abstract it.
Note that even 1 (= 1 millisecond) causes disastrous performance
degradation.
rework threads MCA framework configury
It now works more like the ompi/mca/rte configury,
modulo some edge items that are special for threading package
linking, etc.
qthreads module

Will be replaced by PRRTE. Ensure that OMPI and OPAL layers build
without reference to ORTE. Setup opal/pmix framework to be static.
Remove support for all PMI-1 and PMI-2 libraries. Add support for
"external" pmix component as well as internal v4 one.
remove orte: misc fixes
- UCX fixes
- VPATH issue
- oshmem fixes
- remove useless definition
- Add PRRTE submodule
- Get autogen.pl to traverse PRRTE submodule
- Remove stale orcm reference
- Configure embedded PRRTE
- Correctly pass the prefix to PRRTE
- Correctly set the OMPI_WANT_PRRTE am_conditional
- Move prrte configuration to the end of OMPI's configure.ac
- Make mpirun a symlink to prun, when available
- Fix makedist with --no-orte/--no-prrte option
- Add a `--no-prrte` option which is the same as the legacy
`--no-orte` option.
- Remove embedded PMIx tarball. Replace it with new submodule
pointing to OpenPMIx master repo's master branch
- Some cleanup in PRRTE integration and add config summary entry
- Correctly set the hostname
- Fix locality
- Fix singleton operations
- Fix support for "tune" and "am" options

The new routine transfers the data asynchronously from the source PE to all
PEs in the OpenSHMEM job. The routine returns immediately. The source and
target buffers are reusable only after the completion of the routine.
After the data is transferred to the target buffers, the counter object
is updated atomically. The counter object can be read either using atomic
operations such as shmem_atomic_fetch or can use point-to-point synchronization
routines such as shmem_wait_until and shmem_test.
