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
accordingly.

The MPI spec defines that the "mpi" and "mpi_f08" module Fortran
bindings support passing by parameters by name. Hence, we need to use
the MPI-spec-defined parameter names ("dummy variables", in Fortran
parlance) for the "mpi" and "mpi_f08" modules.
Specifically, Fortran allows calls to procedures to be written with
keyword arguments, e.g., "call mpi_sizeof(x=x,size=rsize,ierror=ier)"
An "explicit interface" for the procedure must be in scope for this to
be allowed in a Fortran program unit. Therefore, the explicit
interface blocks we provide in the "mpi" and "mpi_f08" modules must
match the MPI published standard, including the names of the dummy
variables (i.e., parameter names), as that is how Fortran programs may
call them.
Note that we didn't find this issue previously because even though the
MPI spec *allows* for name-based parameter passing, not many people
actually use it. I suspect that we might have some more incorrect
parameter names -- we should probably do a full "mpi" / "mpi_f08"
module parameter name audit someday.
Thanks to Themos Tsikas for reporting the issue and supplying the
initial fix.

* Add a configure time option to rename libmpi(_FOO).*
- `--with-libmpi-name=STRING`
* This commit only impacts the installed libraries.
Internal, temporary libraries have not been renamed to limit the
scope of the patch to only what is needed.
For example:
```shell
shell$ ./configure --with-libmpi-name=wookie
...
shell$ find . -name "libmpi*"
shell$ find . -name "libwookie*"
./lib/libwookie.so.0.0.0
./lib/libwookie.so.0
./lib/libwookie.so
./lib/libwookie.la
./lib/libwookie_mpifh.so.0.0.0
./lib/libwookie_mpifh.so.0
./lib/libwookie_mpifh.so
./lib/libwookie_mpifh.la
./lib/libwookie_usempi.so.0.0.0
./lib/libwookie_usempi.so.0
./lib/libwookie_usempi.so
./lib/libwookie_usempi.la
shell$
```
The libmpi_*.la fortran libraries make some direct calls to
libopen-pal.la. In many (most?) cases, having libmpi_* link
against libmpi is sufficient (because libmpi pulls in libopen-pal).
But when building RPMs on SLES, some compiler/linker flags are used
that seem to make this implicit linking not sufficient -- we get
missing opal symbols when creating libmpi_mpifh.la. So link in
open-pal directly (vs. indirectly), which solves the problem.
This commit adds support for MPI_Aint_add and MPI_Aint_diff. These
functions are implemented as macros in C (explicitly allowed by
MPI-3.1). The fortran implementations are a similar mess to the
MPI_Wtime implementations.

Ticket 4917 --> https://svn.open-mpi.org/trac/ompi/ticket/4917
What started as a simple ticket ended up reaching the way up to the
MPI Forum.
It turns out that we are supposed to have MPI_SIZEOF for all Fortran
interfaces: mpif.h, the mpi module, and the mpi_f08 module.
It further turns out that to properly support MPI_SIZEOF, your Fortran
compiler *has* support the INTERFACE keyword and ISO_FORTRAN_ENV. We
can't use "ignore TKR" functionality, because the whole point of
MPI_SIZEOF is that the implementation knows what type was passed to it
("ignore TKR" functionality, by definition, throws that information
away). Hence, we have to have an MPI_SIZEOF interface+implementation
for all intrinsic types, kinds, and ranks.
This commit therefore adds a perl script that generates both the
interfaces and implementations for MPI_SIZEOF in each of mpif.h, the
mpi module, and mpi_f08 module (yay consolidation!).
The perl script uses the results of some new configure tests:
* check if the Fortran compiler supports the INTERFACE keyword
* check if the Fortran compiler supports ISO_FORTRAN_ENV
* find the max array rank (i.e., dimension) that the compiler supports
If the Fortran compiler supports both INTERFACE and ISO_FORTRAN_ENV,
then we'll build the MPI_SIZEOF interfaces. If not, we'll skip
MPI_SIZEOF in mpif.h and the mpi module. Note that we won't build the
mpi_f08 module -- to include the MPI_SIZEOF interfaces -- if the
Fortran compiler doesn't support INTERFACE, ISO_FORTRAN_ENV, and a
whole bunch of ther modern Fortran stuff.
Since MPI_SIZEOF interfaces are now generated by the perl script, this
commit also removes all the old MPI_SIZEOF implementations (which were
laden with a zillion #if blocks).

Ticket 4736 --> https://svn.open-mpi.org/trac/ompi/ticket/4736
Older gfortran compilers (e.g., the gfortran that ships in RHEL5) do
not support ISO_C_BINDING, and therefore do not support the
TYPE(C_PTR) type. As such, they cannot support the overloaded
interfaces for MPI_WIN_ALLOCATE_SHARED and MPI_SHARED_QUERY that are
mandated in MPI-3.
So we separate those interfaces out into a separate .F90 file that is
#include'd in the tkr mpi.F90 file. In this separate .F90 file, we
use an #if to determine whether the compiler supports ISO_C_BINDING or
not.
Also re-jiggered the order of testing in ompi_setup_mpi_fortran.m4: we
now need to test whether the compiler supports ISO_C_BINDING even when
we're only building the mpi module (not strictly when we're building
the mpi_f08 module).
Finally, tweaked the use-mpi-tkr/Makefile.am to:
* Add some proper dependencies for mpi.F90
* Allow the general AM compilation to be used instead of supplying a
specific rule for compiling mpi.F90

There is more comprehensive work regarding MPI_SIZEOF coming, but the
Fortran working group in the MPI Forum is debating this internally,
and I'm still doing more testing to get a final solution. So for the
moment, just remove real*16 and complex*32 support so that it compiles
porperly with older compilers (that do not support real*16 and
complex*32).

This is part one of several Fortran improvements and fixes. This
first part removes the now-defunct scripts that are used to generate
the .f90 files in the use-mpi-tkr implementation, and just commits the
output from those scripts. This makes long-term maintenance of the
use-mpi-tkr implementation simpler.

This configure option was only relevant when we were generating TKR
"use mpi" interfaces for MPI subroutines with choice buffers. Now
that we aren't, the only interface that needs to accept a choice
buffer is MPI_SIZEOF (which we have to provide).
And since there's now only several dozen interfaces in the "mpi" TKR
module, there's no reason to not generate ''all'' possible array rank
values (when there were thousands of interfaces, generating 4-vs-7
array ranks per interface per type was a big deal). The default used
to be 4; now we can just hard-code it to 7, the max possible value for
Fortran 2003 (I think the max was raised ?to 11? in F2008, but let's
not go there for now).

Revert the Fortran mpi module default size to "small", meaning that we
won't provide interfaces for MPI subroutines that take a choice buffer
any more. The short version is that MPI-3 p610:34-41 disallows it.
This commit simply removes all these subroutines from the build
process (i.e., remove them from nodist_libmpi_usempi_la_SOURCES).
Since MPI-3 actually forbids providing these interfaces, I'll do a
second commit to actually remove all the scripts and associated
Makefile.am junk.

This commit was SVN r29265.
This patch reshape the way we deal with topologies completely. Where
our topologies were mainly storage components (they were not capable
of creating the new communicator), the new version is built around a
[possibly] common representation (in mca/topo/topo.h), but the functions
to attach and retrieve the topological information are specific to each
component. As a result the ompi_create_cart and ompi_create_graph functions
become useless and have been removed.
In addition to adding the internal infrastructure to manage the topology
information, it updates the MPI interface, and the debuggers support and
provides all Fortran interfaces.
