Nathan Hjelm 0b8baa217d ompi: remove obsolete c++ bindings
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.

.SH INPUT PARAMETERS
.ft R
.TP 1i
group
Group (handle).
.TP 1i
n
Number of elements in array ranks (integer).
.TP 1i
ranks
Array of integer ranks in group not to appear in newgroup.
.SH OUTPUT PARAMETERS
.ft R
.TP 1i
newgroup
New group derived from above, preserving the order defined by group (handle).
.ft R
.TP 1i
IERROR
Fortran only: Error status (integer).
.SH DESCRIPTION
.ft R
The function MPI_Group_excl creates a group of processes newgroup that is obtained by deleting from group those processes with ranks ranks[0], \&... ranks[n-1]. The ordering of processes in newgroup is identical to the ordering in group. Each of the n elements of ranks must be a valid rank in group and all elements must be distinct; otherwise, the call is erroneous. If n = 0, then newgroup is identical to group.
.SH NOTE
.ft R
Currently, each of the ranks to exclude must be a valid rank in the group and all elements must be distinct or the function is erroneous. This restriction is per the draft.
.SH ERRORS
Almost all MPI routines return an error value; C routines as the value of the function and Fortran routines in the last argument.
.sp
Before the error value is returned, the current MPI error handler is
called. By default, this error handler aborts the MPI job, except for I/O function errors. The error handler may be changed with MPI_Comm_set_errhandler; the predefined error handler MPI_ERRORS_RETURN may be used to cause error values to be returned. Note that MPI does not guarantee that an MPI program can continue past an error.
