is the last one on the list and as on C the caller "make it right" this addition
will not affect the way we handle the user defined copy functions. Only the C
version of the function has this additional parameter. As it represent the pointer
to the newly created MPI object It hold the key to allow us to modify the new
object (communicator, window or type) depending on some key stored on the initial
communicator.

flag, new flags to be included when convertor is initialized
- modified pml/btl module defs and added stub functions for diagnostic
output routines to dump state of queues / endpoints
- updates to data reliability pml

- Use the datatype-checks of bindings.h within recv.
However, for the time being disable the check for overlapped,
as it is not correctly set.

args from the old data-type. As this args are only read-only, I don't want to have several
copies around, so I add a reference count to them and simply attach them to the new
datatype. The args array now get freed only when the last reference dissapear.

you can't be in a post and a start at the same time, and that is clearly
legal to do
* Fix interptretation of when the epochs start for MPI_Fence. Only start
an epoch if communication actually occurs, otherwise it isn't actually
an epoch. I don't know who thought that wording in the MPI standard
was a good idea, but can't change it now...

MPI-2:6.3.4 says about reduction operations
* Have the point-to-point one-sided component spew a warning and return
an error if a non-predefined datatype is used with an MPI_OP other
than MPI_REPLACE. Yes, this violates the MPI standard, but it's the
best we can do until George and I implement support for figuring out
where all the locations to update are..

Note, the checksums are not enabled currently, setting to zero as the
convertor is not ready for checksums yet.
Also, we can't call unpack/pack on convertor with 0 bytes, otherwise it
crashes.

- Add more checks on the params to ensure that the user conformed to
MPI-2 (i.e., can have MPI_UNDEFINED for p *or* r in the real/complex
functions, but not both)
- Always return MPI_ERR_ARG, not MPI_ERR_OTHER -- seems to make a
little more sense here, since any errors that are returned are
solely because of the arguments that were passed into the function

- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)

* Implement win_lock and win_unlock in the pt2pt component. Not well
tested, but appears to move bits if properly motivated...
This commit was SVN r8922.
* Implement fortran handle -> c handle tracking
* Remove some unneeded locking around free lists (the free list
macros do their own locking)
* Try to be a bit more memory friendly with the w_mode setting /
checking

complete, but stable enough that it will have no impact on general development,
so into the trunk it goes. Changes in this commit include:
- Remove the --with option for disabling MPI-2 onesided support. It
complicated code, and has no real reason for existing
- add a framework osc (OneSided Communication) for encapsulating
all the MPI-2 onesided functionality
- Modify the MPI interface functions for the MPI-2 onesided chapter
to properly call the underlying framework and do the required
error checking
- Created an osc component pt2pt, which is layered over the BML/BTL
for communication (although it also uses the PML for long message
transfers). Currently, all support functions, all communication
functions (Put, Get, Accumulate), and the Fence synchronization
function are implemented. The PWSC active synchronization
functions and Lock/Unlock passive synchronization functions are
still not implemented

functionality. This is a global registration, so all components have to be made
aware of the registration -- therefore, do things at the component level, not the
module level.

This flag is inherited by all datatypes create with unavailable datatypes. Basically, we let the user create the wrong datatype but we dont let him using it for any pt2pt communications or any pack/unpack.

restoring the PMPI version. A variety of reasons for this:
- mpi.h was blinding using inline in a C header without the configrue mojo
properly set it, as mpi.h doesn't include ompi_config.h. This eventually
would have caused a borked build.
- mpi.h and mpif.h were never updated to not include PMPI_W{tick,time} as
a proper prototype
- The C++ and F90 bindings didn't do the right things when there was no
PMPI version of the C call, but profiling was enabled
- Since we only use gettimeofday, the function call overhead really doesn't
matter
This should probably go to the 1.0 branch

REDUCE_SCATTER to more thoroughly check the datatype/op combination
to see if it's valid or not. If it's not, print a meaningful error
message rather than "Invalid MPI_Op" indicating what specifically
was wrong (therefore hopefully helping users track down where in the
code the problem is, and/or telling us that there's a reduction
operation combo that we don't support that we should)
- The check for whether a datatype is intrinsic needed to be updated
-- it's not sufficient to check that dtype->id < DT_MAX_PREDEFINED;
you really need to check the PREDEFINED flag on the datatype.
Thanks to George for this fix (only intrinsics have a meaningful
value in dtype->id).

at the top-level MPI API function. This allows two kinds of
scenarios:
1. MPI_Ireduce(..., op, ...);
MPI_Op_free(op);
MPI_Wait(...);
For the non-blocking collectives that we're someday planning -- to
make them analogous to non-blocking point-to-point stuff.
2. Thread 1:
MPI_Reduce(..., op, ...);
Thread 2:
MPI_Op_free(op);
Granted, for #2 to occur would tread a fine line between a correct and
erroneous MPI program, but it is possible (as long as the Op_free was
*after* MPI_reduce() had started to execute). It's more realistic
with case #1, where the Op_free() could be executed in the same thread
or a different thread.

AM_INIT_AUTOMAKE, instead of the deprecated version.
* Work around dumbness in modern AC_INIT that requires the version
number to be set at autoconf time (instead of at configure time, as
it was before). Set the version number, minus the subversion r number,
at autoconf time. Override the internal variables to include the r
number (if needed) at configure time. Basically, the right thing
should always happen. The only place it might not is the version
reported as part of configure --help will not have an r number.
* Since AM_INIT_AUTOMAKE taks a list of options, no need to specify
them in all the Makefile.am files.
* Addes support for subdir-objects, meaning that object files are put
in the directory containing source files, even if the Makefile.am is
in another directory. This should start making it feasible to
reduce the number of Makefile.am files we have in the tree, which
will greatly reduce the time to run autogen and configure.

* don't know what I was thinking, but can't use the MCA_PML_CALL macro on
the two data values, as they don't have things that the macro can
expand into
