27cea44a9c Fix a number of issues with the ompi_ptr_t:
* 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

bc3250fe6f Fix issue where messages could start arriving before the window was
fully initialized, especially during lock/unlock, which doesn't use MPI
collectives for synchronization (unlike Fence)

b5b6f4c4bf Remove check for epoch on the receiver side, as this is a race condition between message arrival, and because we'll be still blocking in a synchronization call, is of no consequence to the user. We do an epoch check on the sending side,
so this isn't an issue there either.  Refs trac:488

0c25f7be09 More One-sided fixes:
* Fix a counter roll-over issue that could result from a large (but
    not excessive) number of outstanding put/get/accumulate calls
    during a single synchronization issues (Refs trac:506)
  * Fix epoch issue with rdma component that would effect PWSC
    synchronization (Refs trac:507)

126a68dc9a Big datatype commit. Remove all unused features of the datatype engine. As the memory
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!!).

06563b5dec Last set of explicit conversions. We are now close to the zero warnings on
all platforms. The only exceptions (and I will not deal with them
anytime soon) are on Windows:
- the write functions which require the length to be an int when it's
  a size_t on all UNIX variants.
- all iovec manipulation functions where the iov_len is again an int
  when it's a size_t on most of the UNIXes.
As these only happens on Windows, so I think we're set for now :)

8852c00c36 Look like a big commit but in fact it address only one issue. The way we're working with
size and diplacement of data-type. After this patch all data can contain size_t bytes
and the displacements are defined as ptrdiff_t. All of the files I was able to compile
have been modified to match this requirement.

14f338b7df Fix for lock/unlock epoch issues. Previously, we did not handle the case
where a window was in both the passive and active side of a lock sequence.

451d362296 MPI_Fence's stupid "I might be in a fence epoch but you can't tell until
I do something else" rule screws me up again.  If we're in a FENCE, but
not in ACCESS | EXPOSE, put us in ACCESS|EXPOSE, as we are now known we
now in a real Fence epoch.  Yay silly MPI standards

8fc278c3a3 Rest of the fix for #325. It uses a bit more space, but now we can reasonably
tell if the remote proc should be in an exposure epoch or not.

2ec0c4f593 * Fix race condition in post/wait/start/complete synchronization where one
epoch's control data could overwrite the previous epoch's data because
    we were reusing data structures between PW and SC.  Instead, we now
    have explicit post_msg and complete_msg counters for completion.

  * Only register the rdma osc callback once, as it turns out that some
    btls (MX) do somethng more than update a table during the register
    call, and each register call sucks up valuable fragments...

688a16ea78 A long time waiting patch. Get rid of the comm->c_pml_procs. It was (and that was
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 ...

e0555889a9 * RMA_SYNC is a more appropriate error message for these than RmA_CONFLICT
* Print a warning error message if a target is not in an exposure epoch
    and an update is received.  This results in the app continuing with
    that call having never happened, rather than evil hangs.

e33c35112b Correct the conversion between int and bool. Apply it on all files except
the one that will be modified by Ralph for the ORTE 2.0. The missing ones
are in the rsh PLS.

c1a77b921d Need to add/subtract modes when dealing with PWSC, since a given window
can be in both a Post and Start state.  Also, the asserts were only
correct assuming that we were never in the post and start state at the
same time, which was obviously silly.

0ba0a60ada * Merge in new version of the pt2pt one-sided communication component,
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)
* Old pt2pt component was renamed "rdma", as it will soon be having
  real RDMA support added to it.

Work was done in a temporary branch.  Commit is the result of the
merge command:
