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.

In order to work around an issue with flang based compilers,
avoid declaring bind(C) constants and use plain Fortran parameter
instead.
For example,
type(MPI_Comm), bind(C, name="ompi_f08_mpi_comm_world") OMPI_PROTECTED :: MPI_COMM_WORLD
is changed to
type(MPI_Comm), parameter :: MPI_COMM_WORLD = MPI_Comm(OMPI_MPI_COMM_WORLD)
Note that in order to preserve ABI compatibility, ompi/mpi/fortran/use-mpi-f08/constants.{c,h}
have been kept even if its symbols are no more referenced by Open MPI.

This commit DELETES the removed MPI1 functions and datatypes from
both the mpi.h header and from the library (they were deleted from the
MPI standard in MPI-3.0).
WARNING: This changes the MPI API in a non-backwards compatible way.
This also removes the configure option that was added in Open
MPI v4.0.x, requiring users to change their apps if they are
using any of these almost 20 year old APIs.
This commit removes the following MPI1 removed functions and datatypes:
MPI_Address
MPI_Errhandler_create
MPI_Errhandler_get
MPI_Errhandler_set
MPI_Type_extent
MPI_Type_hindexed
MPI_Type_hvector
MPI_Type_struct
MPI_Type_UB
MPI_Type_LB

Refs https://github.com/open-mpi/ompi/issues/6278.
This commit is intended to be cherry-picked to v4.0.x and
the following commit will ammend to this functionality for
master's removal.
Changes the prototypes for MPI removed functions in the
following ways:
There are 4 cases:
1) User wants MPI-1 compatibility (--enable-mpi1-compatibility)
MPI_Address (and friends) are declared in mpi.h with
deprecation notice
2) User does not want MPI-1 compatibility, and has a C11-capable
compiler
Declare an MPI_Address (etc.) macro in mpi.h, which will
cause a compile-time error using _Static_assert C11 feature
3) User does not want MPI-1 compatibility, and does not have a
C11-capable compiler, but the compiler supports error function
attributes.
Declare an MPI_Address (etc.) macro in mpi.h, which will
cause a compile-time error using error function attribute.
4) User does not want MPI-1 compatibility, and does not have a
C11-capable compiler, or a compiler that supports error
function attributes.
Do not declare MPI_Address (etc.) in mpi.h at all.
Unless the user is compiling with something like -Werror,
this will allow the user's code to compile. We are
choosing this because it seems like a losing battle to
make some kind of compile time error that is friendly to
the user (and doesn't make it look like mpi.h itself is broken).
On v4.0.x, this will allow the user code to both compile
(albeit with a warning) and link (because the MPI_Address
will be in the MPI library because we are preserving ABI
back to 3.0.x).
On master/v5.0.x, this will allow the user code to compile,
but it will fail to link (because the MPI_Address symbol will
not be in the MPI library).

... and add `MPI_COMPLEX4`.
This commit changes values of existing `OMPI_DATATYPE_MPI_*` macros.
This change does not affect ABI compatibility of `libmpi.so` and the
like because these values are only used in OMPI internal code.
On the other hand, `ompi_datatype_t::id` values of existing datatypes
are not changed and 73 is newly assigned to for `MPI_COMPLEX4` to
retain ABI compatibility.

When compiling mpi.h with a modern C++ compiler and a high degree of
pickyness (e.g., -Wold-style-cast), casting using (void*) in the
OMPI_PREDEFINED_GLOBAL and MPI_STATUS*_IGNORE macros will emit
warnings. So if we're compiling with a C++ compiler, use C++'s
static_cast<> instead of (void*).

Commit 89da9651b inadvertantly #if'ed out both deprecated *and*
removed items from mpi.h. The intent was only to #if out items that
have been *removed* from the MPI specification and leave all items
that are merely deprecated.
This commit also re-orders the deleted typedef+functions to be in the
same order as they are listed in MPI-3.1 chapter 17, just to make
verifying/checking the code easier.
Note that --enable-mpi1-compatibility can still be used to restore
prototypes for the items that have been removed from the MPI
specification (e.g., MPI_Address()).

The old/deprecated form of the file errhandler typedef used "fn" as a

"function" to match the MPI API name and avoid confusion.

This commit adds a new configure option: --enable-mpi1-compat. Without
this option we will no longer provide APIs, typedefs, and defines that
were removed from the standard in MPI-3.0. This option will exist for
one major release (Open MPI v4.x.x) and then the option and associated
code will be removed in Open MPI v5.x.x. Open MPI has already
internally prepared for this change. Please prepare your codes

* Optimize the datatype creation.
The internal array of counts of predefined types is now only created
when needed, which is either in a heterogeneous environment, or when
one call get_elements. It saves space and makes the convertor creation a
little faster in some cases.
Rearrange the fields in the datatype description structs.
The macro OPAL_DATATYPE_INIT_PTYPES_ARRAY had a bug, and the
static array was only partially created. All predefined types should
have the ptypes array created and initialized.

As we changed the ABI (forcing a major release), we can limit

This commit add the following Fortran named constants which are
defined in the MPI standard but are missing in Open MPI.
- `MPI_LONG_LONG` (defined as a synonym of `MPI_LONG_LONG_INT`)
- `MPI_CXX_FLOAT_COMPLEX`
- `MPI_C_BOOL`
And this commit also changes the value of the following Fortran
named constant for consistency.
- `MPI_C_COMPLEX`
`(MPI_C_FLOAT_COMPLEX` is defined as a synonym of this)
Each needs a different solution described below.
For `MPI_LONG_LONG`:
The value of `MPI_LONG_LONG` is defined to have a same value
as `MPI_LONG_LONG_INT` because of the following reasons.
1. It is defined as a synonym of `MPI_LONG_LONG_INT` in
the MPI standard.
2. `MPI_LONG_LONG_INT` and `MPI_LONG_LONG` has a same value
for C in `mpi.h`.
3. `ompi_mpi_long_long` is not defined in
`ompi/datatype/ompi_datatype_module.c`.
For `MPI_CXX_FLOAT_COMPLEX`:
Existing `MPI_CXX_COMPLEX` is replaced with `MPI_CXX_FLOAT_COMPLEX`
bacause `MPI_CXX_FLOAT_COMPLEX` is the right name defined in MPI-3.1
and `MPI_CXX_COMPLEX` is not defined in MPI-3.1 (nor older).
But for compatibility, `MPI_CXX_COMPLEX` is treated as a synonym
of `MPI_CXX_FLOAT_COMPLEX` on Open MPI.
For `MPI_C_BOOL`:
`MPI_C_BOOL` is newly added. The value which `MPI_C_COMPLEX` had
used (68) is assinged for it because the value becomes no longer
in use (described later) and it is a suited position as a datatype
added on MPI-2.2.
For `MPI_C_COMPLEX`:
Existing `MPI_C_FLOAT_COMPLEX` is replaced with `MPI_C_COMPLEX`
and `MPI_C_FLOAT_COMPLEX` is changed to have the same value.
In other words, make `MPI_C_COMPLEX` the canonical name and
make `MPI_C_FLOAT_COMPLEX` an alias of it.
This is bacause the relation of these datatypes is same as
the relation of `MPI_LONG_LONG_INT` and `MPI_LONG_LONG`, and
`MPI_LONG_LONG_INT` and `MPI_LONG_LONG` are implemented like that.
But in the datatype engine, we use `ompi_mpi_c_float_complex`
instead of `ompi_mpi_c_complex` as a variable name to keep
the consistency with the other similar types such as
`ompi_mpi_c_double_complex` (see George's comment in open-mpi/ompi#1927).
We don't delete `ompi_mpi_c_complex` now because it is used in
some other places in Open MPI code. It may be cleand up in the future.
In addition, `MPI_CXX_COMPLEX`, which was defined only in the Open MPI
Fortran binding, is added to `mpi.h` for the C binding.
This commit breaks binary compatibility of Fortran `MPI_C_COMPLEX`.
When this commit is merged into v2.x branch, the change of
`MPI_C_COMPLEX` should be excluded.
