88f0845c44 - let the pt2pt component compile with threads enabled
This commit was SVN r14725.

38eab3613b * Fix race condition with the pending_{in,out} variables -- if we're going
to do while(...) { } then we can't change the variables in the ... 
    atomically, but should do it while holding the module lock.
  * 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.

2b4b754925 Some much needed cleanup of the point-to-point one-sided component...
* 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.

51f286d737 Just like r14289 on the ORTE trunk:
Per discussions with Brian and Ralph, make a slight correction in
where components are installed. Use $pkglibdir, not $libdir/openmpi,
so that when compiled in the orte trunk, components are installed to
the right directory (because the component search patch is checking
$pkglibdir).

241545a098 Back out r14073 - it speeds up TCP latency / bandwidth but at the same time
it kills ROMIO and one-sided performance when using only TCP.  The problem
is that it only allows those two to be progressed every couple of seconds,
leading to what looks like hangs in the one-sided tests (and the ROMIO stuff,
although people seem to not notice that at this point).

95c0a17b9a Send the unlock request before starting the requests. We won't unlock until we get an ack from the remote side,
so there's no longer a race there (I used to do the unlock request last, after local completion of all the
requests completed, to try to avoid having the passive side reply to the active side, but I don't do that
anymore).  The unlock side will not "unlock" the window until it actually receives the correct number of results,
so we're good there.

This fixes an issue where we would receive data on the remote side we weren't expecting that could cause
us to release a lock before it really should have been released to the requesting peer.  It could also
cause a deadlock if one of the processes trying to unlock was "self", as that would result in the active
unlock never sending the unlock request, even though it sent the payload, which could cause a counter
that should always be positive to hit -1, causing an infinite loop that could only be solved by
popping up the stack, which was an impossibility.

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 :)

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 ...

612570134f The request management framework has been redesigned. The main idea is
to let the PML (or io, more generally the low level request manager)
to have it's own release function (what was before the req_fini). This
function will only be called from the low level while the req_free will
be called from the upper level (MPI layer) in order to mark the request
as not used by the user anymore.

From the request point of view the requests will be marked as inactive
everytime we read their status (true for persistent as well). As 
MPI_REQUEST_NULL is already marked as inactive, the test and wait functions
are simpler. The drawback is that now we have to change in the
ompi_request_{test|wait} the req_status of the request once we get it's
status.

285581dff2 More endian-related cleanups:
- moved hton64 and ntoh64 from the bunch of places it had been copied
    into one header file
  - properly set and use the btl_tcp's nbo option to put things in
    network byte order on the wire if both sides don't have the same
    endianness
  - Put the OB1 PML's headers (with a couple exceptions I need to discuss
    with Tim) in network byte order on the wire if both sides don't have
    the same endianness
  - since it was needed for the TCP BTL, move the orte_process_name_t
    HTON and NTOH macros from the TCP OOB to ns_types.h

d5e0ea3590 * Post and Start should only check their epoch types for conflicts, otherwise
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...

27b8430e8f * update MPI_ACCUMULATE to perform it's parameter checking based on what
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..

44d13b0bab * add a bunch of (currently disabled) debugging output statements
* fix a silly bug where we weren't adding a long accumulate message to
  the pending long messages list, so we hung if a long accumulate
  occurred.  Still having some memory issues on one of the tests I'm
  running - need to move over to Linux and Valgrind after some sleep.

eb7e722588 * clean up some of the debugging in the onesided code so that I can understand
what is going on
* Fix a dumb error where if a lock was released and another was pending, I
  would send a lock *request* to the queued process, rather than giving
  him the lock and sending him a lock *ack*.  Turns out requests and
  acks are different things :)

566a050c23 Next step in the project split, mainly source code re-arranging
- 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)

  bit closer...

b1d2424013 Merge in present work on the MPI-2 onesided chapter. The current code is not
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
