Use "prte" instead of "prun" for proxy execution of cmds like mpirun.
This avoids the fork/exec-rendezvous complexities and should result in
more reliable operation.

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.

The opal_gethostname() function provides a more robust mechanism
to retrieve the hostname than gethostname(), which can return
results that are not null-terminated, and which can vary in its
behavior from system to system.
opal_gethostname() just returns the value in opal_process_info.nodename;
this is populated in opal_init_gethostname() inside opal_init.c.
-Changed all gethostname calls in opal subtree to opal_gethostname
-Changed all gethostname calls in orte subtree to opal_gethostname
-Changed all gethostname calls in ompi subdir to opal_gethostname
-Changed all gethostname calls in oshmem subdir to opal_gethostname
-Changed opal_if.c in test subdir to use opal_gethostname
-Changed opal_init.c to include opal_init_gethostname. This function
returns an int and directly sets opal_process_info.nodename per
jsquyres' modifications.

This commit changes values of existing `OMPI_DATATYPE_MPI_*` macros.
This change does not affect ABI compatibility of `libmpi.so` and the

The type `short float`, which is proposed in ISO/IEC JTC 1/SC 22 WG 14
(C WG), is not supported by most compilers yet. But some compilers
(including gcc 7 for AArch64 and clang 6) support `_Float16`, which
is defined in ISO/IEC TS 18661-3:2015 (ISO/IEC JTC 1/SC 22/WG 14 N1945)
as an extensions for C. If it is detected in `configure`, it is used
as an alternate type of `short float` in Open MPI internal code.
This commit adds a `configure` option `--enable-alt-short-float=TYPE`.
It can be used to specify a type other than `short float` and `_Float16`
as the alternate type.

1/SC 22 WG 14 (C WG) for mainly IEEE 754-2008 binary16, a.k.a.

By this commit, `short float` and `short float _Complex` are detected
in `configure` and used in Open MPI internal code. `MPI_SHORT_FLOAT`
and its complex number version are not added yet.

The Open MPI code base assumed that asprintf always behaved like
the FreeBSD variant, where ptr is set to NULL on error. However,
the C standard (and Linux) only guarantee that the return code will
be -1 on error and leave ptr undefined. Rather than fix all the
usage in the code, we use opal_asprintf() wrapper instead, which
guarantees the BSD-like behavior of ptr always being set to NULL.
In addition to being correct, this will fix many, many warnings
in the Open MPI code base.

This commit removes the --with-mpi-thread-multiple option and forces
MPI_THREAD_MULTIPLE support. This cleans up an abstration violation
in opal where OMPI_ENABLE_THREAD_MULTIPLE determines whether the
opal_using_threads is meaningful. To reduce the performance hit on
MPI_THREAD_SINGLE programs an OPAL_UNLIKELY is used for the
check on opal_using_threads in OPAL_THREAD_* macros.
This commit does not clean up the arguments to the various functions
that take whether muti-threading support is enabled. That should be
done at a later time.

As of v15.7, the PGI Fortran compiler does not properly support how
Open MPI uses the "USE ... ONLY" Fortran syntax to include modules
with conflicting symbol definitions (interestingly, pgfortran only has
a problem with this when compiling with -g).
In short, OMPI uses "USE :: module_aaa, ONLY: foo" and "USE ::
module_bbb, ONLY: bar" to use modules aaa and bbb, even though they
contain conflicting definitions for some symbols. However, the use of
the ONLY clause should preclude the inclusion of the conflicting
symbols -- as the word implies, it should direct the compiler to
*only* use the symbols identified by the clause (i.e., foo and bar, in
this example).
This commit adds a configure test for this capability. If the
compiler fails to build a simple test that mimics this behavior, then
disable the mpi_f08 bindings.

This commit does two things. It removes checks for C99 required
