the page address three situations:
1. if the array of requests are all REQUEST_NULL, set flag=true and
index=MPI_UNDEFINED
2. if the array of requests are not all REQUEST_NULL, if any of them
finished, set flag=true and index=whatever_the_index_was
3. if the array of requests are not all REQUEST_NULL, if none of them
finished, set flag=false and index=MPI_UNDEFINED
With regards to the index value, we are currently doing 1 and 2, but
not 3. More specifically, index should be set to MPI_UNDEFINED if no
requests are found to have completed (regardless of whether they are
REQUEST_NULL or not).
This patch fixes this problem.

aware of the registration -- therefore, do things at the component level, not the
module level.

case of:
sizeof(MPI_Flogical) != sizeof (int)
and
Fortran value of .TRUE. != 1
as is often the case.
- Check in configure the value of .TRUE., the C-type coresponding to
logical and check, that fortran compiler does not do something strange
with arrays of logicals
- Convert all occurrences of logicals in the fortran wrappers, only
in case it is needed.
*Please note* Implementation of MPI_Cart_sub needed special treatment.
- Output these value in ompi_info -a
- Clean up the prototypes_mpi.h to just have a single definition and
thereby deleting the necessity for prototypes_pmpi.h
- configured, compiled and tested with F90-program, which uses
MPI_Cart_create and MPI_Cart_get:
linux ia32, gcc (no testing, as no f90)
linux ia32, gcc --disable-mpi-f77 --disable-mpi-f90 (had a bug there)
linux ia32, icc-8.1
linux opteron, gcc-3.3.5, pgcc, pathccx/pathf90 (tested just
pgi-compiler)
linux em64t, gcc, icc-8.1 (tested just icc)

increase the previous connection code was broken. It can take as much as 60 seconds to connect
64 processes. Now we do not create the connections when we add the procs but only when we send
them the first message. Now it take only 1.6 seconds to setup a 64 procs MPI job over MX (doing a 2 steps barrier in order to insure that we create all the connections).

displacements in scatterv are given in multiples of the sendtype.
This fix should probably make to v1.0.1 as well?

argument is defined to be
integer (KIND=MPI_ADDRESS_KIND)
we have to map that to an MPI_Aint in the f->c interface, else the
typecast back from the C to the Fortran interface will be wrong as well.
The same holds (at least) for all other new MPI-2 datatype functions
which take a byte-displacement or an address as an argument.

Thanks to Anthony Chan for pointing this out.
Note that these will only work for the Fortran compiler that Open MPI
was configured with -- since these values, are, by definition,
single-value, they cannot support all 4 values that Open MPI may
generate for the different Fortran name-mangling schemes. A lengthy
comment in ompi_mpi_init.c explains this in more detail. Added to the
README to explain this situation, as well as the forthcoming
.TRUE. Fortran fixes.

- Separate out the registration of the MCA params into a standalong
function that is invoked by ompi_mpi_init() (so that ompi_info can
see these params)
- Rename the params to "mpi_ddt_*" instead of "datatype_*" so that
they fit into the common naming scheme

is labeled as internal so the users will not see it but it is not read-only so we can still
play with it (that's for our internal tests). This is supposed to dissapear later after the
next (or next next) release of the MX library, but we need it now as a quick fix before the
release.

Remove the old function from the dt_unpack.c and activate the new one from dt_copy.c
Add a MCA param ompi_copy_debug to get messages about the local memory copies in the new function.
Slightly change the prototype of the function to keep the compilers happy on some platforms.
