This commit:
* Adds the configury to figure out how many Fortran INTEGERs are
necessary to represent the C MPI_Status (which now includes a size_t
member).
* Sets MPI_STATUS_SIZE to this value in mpif-config.h.in.
* Adds a big comment in status_c2f.c explaining why the no changes
were necessary to how we copy statuses between Fortran and C.

--enable-mpi-interface-warning (default OFF), but can be
selectively turned on passing

Using icc, gcc < 4.5, warnings (such as in mpi2basic_tests) show:
type_vector.c:83: warning: ‘MPI_Type_hvector’ is deprecated
(declared at /home/../usr/include/mpi.h:1379)
Using gcc-4.5 (gcc-svn) these show up as:
type_vector.c:83: warning: ‘MPI_Type_hvector’ is deprecated
(declared at /home/../usr/include/mpi.h:1379):
MPI_Type_hvector is superseded by MPI_Type_create_hvector in MPI-2.0
Jeff and I propose to turn such warnings on with Open MPI-1.7 by default.
- Detection of user-level compiler is handled using the preprocessor
checks of GASnet's other/portable_platform.h (thanks to Paul Hargrove
and Dan Bonachea) adapted into ompi/include/mpi_portable_platform.h
(see comments).
The OMPI-build time detection is output (Familyname and Version)
with ompi_info.
This functionality (actually any upcoming __attribute__) are turned
off, if a different compiler (and version) is being detected.
- Note, that any warnings regarding (user-compiler!=build-compiler)
as discussed in the RFC are _not_ included for now.

* New "op" MPI layer framework
* Addition of the MPI_REDUCE_LOCAL proposed function (for MPI-2.2)
= Op framework =
Add new "op" framework in the ompi layer. This framework replaces the
hard-coded MPI_Op back-end functions for (MPI_Op, MPI_Datatype) tuples
for pre-defined MPI_Ops, allowing components and modules to provide
the back-end functions. The intent is that components can be written
to take advantage of hardware acceleration (GPU, FPGA, specialized CPU
instructions, etc.). Similar to other frameworks, components are
intended to be able to discover at run-time if they can be used, and
if so, elect themselves to be selected (or disqualify themselves from
selection if they cannot run). If specialized hardware is not
available, there is a default set of functions that will automatically
be used.
This framework is ''not'' used for user-defined MPI_Ops.
The new op framework is similar to the existing coll framework, in
that the final set of function pointers that are used on any given
intrinsic MPI_Op can be a mixed bag of function pointers, potentially
coming from multiple different op modules. This allows for hardware
that only supports some of the operations, not all of them (e.g., a
GPU that only supports single-precision operations).
All the hard-coded back-end MPI_Op functions for (MPI_Op,
MPI_Datatype) tuples still exist, but unlike coll, they're in the
framework base (vs. being in a separate "basic" component) and are
automatically used if no component is found at runtime that provides a
module with the necessary function pointers.
There is an "example" op component that will hopefully be useful to
those writing meaningful op components. It is currently
.ompi_ignore'd so that it doesn't impinge on other developers (it's
somewhat chatty in terms of opal_output() so that you can tell when
its functions have been invoked). See the README file in the example
op component directory. Developers of new op components are
encouraged to look at the following wiki pages:
https://svn.open-mpi.org/trac/ompi/wiki/devel/Autogenhttps://svn.open-mpi.org/trac/ompi/wiki/devel/CreateComponenthttps://svn.open-mpi.org/trac/ompi/wiki/devel/CreateFramework
= MPI_REDUCE_LOCAL =
Part of the MPI-2.2 proposal listed here:
https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/24
is to add a new function named MPI_REDUCE_LOCAL. It is very easy to
implement, so I added it (also because it makes testing the op
framework pretty easy -- you can do it in serial rather than via
parallel reductions). There's even a man page!

corrections to non-windows files (but within ifdef __WINDOWS__)

in orte runtime, add windows sockets handling and object construction.
This commit was SVN r20110.
Rationale:
1. This value has already changed since v1.2 (v1.2 MPI_MAX_PORT_NAME
== 36). Hence, this commit simply increases the value from a
previous change.
1. The changes does increase OMPI's memory footprint slightly, but
only when using MPI-2 dynamics. So it is expected that the change
will have minimal impact on the overall footprint.
1. The change is helpful for nodes that have 4 or more IP networks
(e.g., regular ethernet and multiple IP-over-<pick your favorite
high-speed network> networks). Without this change, invoking
MPI_COMM_SPAWN on hosts with 4 or more IP networks will fail
because we'll exceed 256 bytes for the port name. Some OMPI
developer test clusters already have this kind of configuration
(e.g., Cisco); it is expected that this is not too common in the
real world yet, but with "manycore" coming, having multiple
IP-based networks in a single server will likely become more
common.

* Various changes to enable 0-dimensional cartesian communicators:
* Set various mtc_* members to NULL when there are 0 dimensions (and
don't bother trying to memcpy these arrays when duplicating the
communicator -- because they're NULL)
* adjust topo_base_cart_sub to correctly handle 0 dimensions
(simplified it a bit)
* adjust a few error codes to return ERR_OUT_OF_RESOURCE
* adjust error checking of CART_CREATE, CART_RANK
* Allow MPI_GRAPH_CREATE to accept 0 == nnodes.

Benefits of this function will be using less memory, compactness and better performance. Thanks to George.
Keep the old memchecker function as well in case of convertor is not available.
