This fixes a bug in the configuration system identified by a
change in the C++ standard. C++20 adds a new mandatory header
named version. This (and any system) header will always be
included with <> and not "". On case-insensitive filesystems
this new header conflicts with the VERSION file at the top
level of the build tree.
To fix this issue Open MPI needs to use -iquote instead of -I
for non-system include paths to ensure that these include are
only searched for the quote form of include. This commit also
adds a check to ensure that if the compiler does not support
-iquote that it falls back to -I until support can be added.

This commit fixes an issue with the include usage in some
ompi source files. These source files are using the <> form
of include when the "" form is correct (as these are internal,
**not** system headers).

PRRTE:
- Begin conversion to use of nspace in place of numeric jobid
- Restore support:
--report-bindings
--display-map

Keep track of the connected procs in vader_add_procs().
Otherwise, the same rank will reconnect the same shmem
segment (rank 0+...) multiple times instead of the next
one as intended.

OpenPMIx fills in a variety of info when it detects that we are in
singleton mode. Best way of detecting it is to look for the "singleton"
at the beginning of the returned nspace.
Make the modex recvs optional so we don't bounce up to the server and
then to the host trying to retrieve job-level info that must be given to
us at job start.

Some of us have platform files that expressly disabled C++ support.
While it is true that v5 no longer supports C++ and thus no longer needs
us to disable it, there seems no reason to make us create platform files
that differentiate based on OMPI version just for that reason.
So if someone asks to "disable" the no-longer-existing support, just
ignore it.

Looks like this was mistakently removed in the conversion to PRRTE.
We still need CFLAGS_WITHOUT_OPTFLAGS for Open MPI's MPI debugger
interface. Not having this functionality means that ompi/debuggers
was being compiled incorrectly, which led to -- among other things --
32 bit builds failing.

Temporary solution for the PML inconsistency issue discussed in #7475.
This patch address 2 things: first it make the PMIx key optional so that
if we are not in a full modex mode we don't do a direct modex, and
second it get the PML info from the vpid 0 instead of from the local
rank.

Restrict the search to the "immediate" range so at worst we check with
our local server and don't go up to the host daemon.

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.
