* Fix dumb communicator creation error when we don't create the progress
stuff (because a window already exists), where we would accidently
jump to the error case.
This commit was SVN r14715.
* Combine polling of the long requests and buffer requests into
one type, and in one place
* Associate the list of requests to poll with the component, not
the individual modules
* add progress thread that sits on the OMPI request structure
and wakes up at the appropriate time to poll the message
list. Not the best, but without some asynch notification
from the PML that a given set of requests has completed, there
isn't much better
* Instead of calling opal_progress() all over the place, move
to using the condition variables like the rest of the project.
Has the advantage of moving it slightly futher along in the
becoming thread safe thing
* Fix a problem with the passive side of unlock where it could
go recursive and cause all kinds of problems, especially
when progress threads are used. Instead, have two parts of
passive unlock -- one to start the unlock, and another to
complete the lock and send the ack back. The data moving
code trips the second at the right time.

* Make sure that the pval always writes to the correct portion of the
lval. This only matters on 32 bit big endian machines.
* On 32 bit machines when assigning to pval, the other 4 bytes of lval
weren't being written, which could lead to bogus data
We use macros so that there aren't casts all over the code and the pval
assignment can occur to the correct 4 bytes. Refs trac:587

* use one-sided datatype check instead of send/receive and check both
the origin and target datatypes
* allow error handler to be set on MPI_WIN_NULL, per standard
* Allow recursive calls into the pt2pt osc component's progress
function

allocation logic is completely done outside the data-type engine (in the PML) there is
no need for any special case inside the data-type engine. There is less arguments for
the ompi_convertor_pack and ompi_convertor_unpack as well (the last field free_after is
not required anymore as there is no memory allocated in the engine itself). This change
affect all components using datatypes. I test most of them, but it might happens that I
miss some ... If it's the case please let me know (don't shoot the pianist!!).

and the displacements are defined as ptrdiff_t. All of the files I was able to compile
have been modified to match this requirement.

long ago) supposed to be used as a cache for accessing the PML procs. But in
all of the PMLs the PML proc contain only one field i.e. a pointer to the ompi_proc.
This pointer can be accessed using the c_remote_group easily. Therefore, there is no
meaning of keeping the PML procs around. Slim fast commit ...

implemented entirely on top of the PML. This allows us to have a
one-sided interface even when we are using the CM PML and MTLs for
point-to-point transport (and therefore not using the BML/BTLs)

real RDMA support added to it.

- 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

* Implement win_lock and win_unlock in the pt2pt component. Not well
tested, but appears to move bits if properly motivated...

bit closer...

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
