* 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.
* Bump reported MPI version in mpi.h to 2.1

Update the version of ROMIO to that which was contained in
MPICH2-1.0.7, plus a few patches from the upstream ROMIO maintainers
(because OMPI uses a few code paths in ROMIO that MPICH2 does not;
there were a few compile bugs in the ROMIO from MPICH2-1.0.7).
Added an info MCA param to be able to tell which version of ROMIO is
contained in OMPI: io_romio_version.
Many, many thanks to romio-maint@mcs.anl.gov for all their help in
integrating this new version of ROMIO into Open MPI.

is still to use the C based wrapper compilers (which have many more features
and are more well tested). The Perl compilers are enabled with the option
--enable-script-wrapper-compilers, which also ignores the option
--disable-binaries (ie --enable-script-wrapper-compilers --disable-binaries
will result in perl-based wrapper compilers being installed, but no other
binaries being installed).
This commit was SVN r18655.
a standalone library named libopenmpi-malloc. Users wanting to
use leave_pinned with ptmalloc2 will now need to link the library
into their application explicitly. All other users will use the
libc-provided allocator instead of Open MPI's ptmalloc2. This change
may be overriden with the configure option enable-ptmalloc2-internal
- The leave_pinned options will now default to using mallopt on
Linux in the cases where ptmalloc2 was not linked in. mallopt
will also only be available if munmap can be intercepted (the
default whenever Open MPI is not compiled with --without-memory-
manager.
- Open MPI will now complain and refuse to use leave_pinned if
no memory intercept / mallopt option is available.
