This commit contains the following changes:
The C++ bindings were removed from the standard in MPI-3.0. This
commit removes the entirety of the C++ bindings as well as the
support configury.
Removes all references to C++ from the man pages. This includes the
bindings themselves, all references to what C++ bindings return,
all not-available comments, and differences between C++ and other
language bindings.
If the user passes --enable-mpi-cxx, --enable-mpi-cxx-seek, or
--enable-cxx-exceptions, print a warning message an abort configure.

There were too many arguments being passed to the compare_exchange_strong
macro. This commit removes the extra arguments and restores the
functionality.

This commit removes the specialized support for Sparc v9 as the
architecture is unsupported. The architecture will continue to
work without CMA and using the GCC built-in atomic support.

This commit removes the unsupported __sync built-in atomics in
favor of the GCC built-ins. The priority order (if not modified
by configure flags) is: C11, custom atomics
(opal/include/opal/sys/*), then GCC built-ins.

This commit removes the reference to ARMv4 and ARMv5. These are
unsupported architectures and no one is testing if CMA is working
on these systems.

IA64 atomic support was deleted some time ago. Some of the references
to the architecture were not removed when the atomic support was. This
commit removes those lingering references. IA64 will continue to work
unsupported with the built-in atomics.

Before this change, the reference counters `opal_util_initialized`
and `opal_initialized` were incremented at the beginning of the
`opal_init_util` and the `opal_init` functions respectively.
In other words, they were incremented before fully initialized.
This causes the following program to abort by SIGFPE if
`--enable-timing` is enabled on `configure`.
```c
// need -lm option on link
int main(int argc, char *argv[])
{
// raise SIGFPE on division-by-zero
feenableexcept(FE_DIVBYZERO);
MPI_Init(&argc, &argv);
MPI_Finalize();
return 0;
}
```
The logic of the SIGFPE is:
1. `MPI_Init` calls `opal_init` through `ompi_rte_init`.
2. `opal_init` changes the value of `opal_initialized` to 1.
3. `opal_init` calls `opal_init_util`.
4. `opal_init_util` calls `opal_timing_ts_func` through
`OPAL_TIMING_ENV_INIT`, and `opal_timing_ts_func` returns
`get_ts_cycle` instead of `get_ts_gettimeofday` because
`opal_initialized` to 1.
(This is the problem)
5. `opal_init_util` calls `get_ts_cycle` through
`OPAL_TIMING_ENV_INIT`.
6. `get_ts_cycle` executes
`opal_timer_base_get_cycles()) / opal_timer_base_get_freq()`
and it raises SIGFPE (division-by-zero) because the OPAL TIMER
framework is not initialized yet and `opal_timer_base_get_freq`
returns 0.
This commit changes the increment timing of `opal_util_initialized`
and `opal_initialized` to the end of `opal_init_util` and the
`opal_init` functions respectively.

1- Remove the common symbols issue: global variable not initialized. (#7424)
Move the variables to local scope within the set_info function.
2- Remove GPFS hints using datashipping: not used anymore
3- Redirect output stream to corresponding fs framework.

The communicator might be not existent yet when mca_fs_gpfs_component_file_query() is called.
Therefore, we need to check it first before calling brodcast function.

The SM BTL was effectively removed a long time ago. All that was left
was a shell that warned people if they tried to use the SM BTL. For
v5.0, we plan to finally remove this ancient shell (and possibly
replace it with vader).

External pmix installs are frequently in non-standard locations and
the path to their shared libraries are not ldconfig'd in because
there may be multiple pmix installs.
The way the configury was set up prior to this patch, the configuration
would fail soon after the PMIX config stuff was called because it
added some pmix lib stuff to the LDFLAGS, resulting in configury tests
for things that require running the configure test to fail.
This patch avoids this problem by resetting the LDFLAGS and LIBS back
to what they were prior to the run of the external PMIX detection.
The CFLAGS setting is left because there are many places in the ompi
and opal source code where pmix_common.h needs to be included.

Hwloc upstream has fixed a problem with embedded "make distcheck" that
was breaking that surfaced when you ran autogen in an Open MPI
tarball.
This submodule update takes in the upstream hwloc fixes for this
issue.
