MPI_Isend.
I filed an RFC for this optimization some time back. It is a
relatively simple optimization. If the data associated with an
MPI_Isend can be put on the wire without allocating an MPI_Request
then do so. In this case we can legally return omp_request_empty
which will correctly indicate that the request is complete and that is
was not cancelled (these are the only requirements on send requests).

Basesmuma was vallocing space for control data then mmapping over that
data. Nothing in the code suggests any need for mmapping a specific
address so I did the following to remove the leak:
- Removed the valloc of the buffer space
- ftruncate the mmaped file to ensure there is sufficient memory to
allocate space for the control data.
Ideally this code should be using opal/shmem but that is a larger
change. Keeping it simple for now.

Ticket 4506 --> https://svn.open-mpi.org/trac/ompi/ticket/4506
r30343 introduced the optimization of putting the OB1 sendreq and
recvreq on the stack for blocking sends and receives. However, the
requests did not contain enough storage for the data that is normally
immediately ''after'' the request (e.g., BTL data).
This commit changes these requests to be pointers and to use alloca()
to get enough total space for the OB1 request and all the associated
data.
The change is smaller than it looks; most of it is just changing from
"foo.bar" to "foo->bar" notation (etc.).
Submitted by Jeff, reviewed by Nathan. But we want George to look at
this (and get a little soak time on the trunk) before moving to v1.8.

This commit fixes leaks of bml endpoints in finalize. A summary of the
bugs/fixes is below.
1) ompi_mpi_finalize used ompi_proc_all to get the list of procs but
never released the reference to them (ompi_proc_all called
OBJ_RETAIN on all the procs returned). When calling del_procs at
finalize it should suffice to call ompi_proc_world which does not
increment the reference count.
2) del_procs is called BEFORE ompi_comm_finalize. This leaves the
references to the procs from calling the pml_add_comm
function. The fix is to reorder the calls to do omp_comm_finalize,
del_procs, pml_finalize instead of del_procs, pml_finalize,
ompi_comm_finalize.
3) The check in del_procs in r2 checked for a reference count of
1. This is incorrect. At this point there should be 2 references:
1 from ompi_proc, and another from the add_procs. The fix is to
change this check to look for a reference count of 22. This check
makes me extremely uncomforable as nothing will call del_procs if
the reference count of a procs is not 2 when del_procs is
called. Maybe there should be an assert since this is a developer
error IMHO.

In abusive MPI communication patterns, sending a UDP ping only once a
second may not be sufficient -- all the UDP pings may be dropped. So
increase the frequency of the pings to every quarter second, and allow
more total pings to be sent.
Total timeout time is still the same (10 seconds) -- we'll just now
try 40 times (i.e., once every quarter second) as opposed to 10 times
(i.e., once a second). Testing has shown that this frequency allows
the connectivity checker to always succeed even in the many-to-one
abusive communication patterns.

When sending PUT_LONG, the data is sent before headers, and sometimes
the header is not flushed immediately. This creates a lot of unexpected

eventually flushes the window, the receiver already has no buffers to
receive the header, which causes a deadlock.

Use type(c_funptr) to "cast" the fortran function pointers to
arbitrary C pointers. In C, we then pick up the appropriate function
pointer type.
Tested with ifort 14.0.2 and gfortran 4.9 snapshot (which is what
identified that the previous method of passing function pointers was
not Fortran'08-compliant).

Junchao Zhang pointed out to me that we had the wrong parameter name
and string length specification for the "version" parameter. This
matters because Fortran allows passing by parameter name
(vs. parameter ordering). Specifically, we had the interface as:
{{{
subroutine MPI_Get_library_version_f08(name,resultlen,ierror)
character(len=MPI_MAX_PROCESSOR_NAME), intent(out) :: name
...etc.
}}}
but it should be:
{{{
subroutine MPI_Get_library_version_f08(version,resultlen,ierror)
character(len=MPI_MAX_LIBRARY_VERSION_STRING), intent(out) :: version
...etc.
}}}
Thankfully, MPI_MAX_PROCESSOR_NAME and MPI_MAX_LIBRARY_VERSION_STRING
are both 255 in OMPI, so there's no ABI issue caused by changing the
length from MMPN --> MMLVS.
The ABI is also unaffected by the parameter name change: if you
compile/link an MPI application calling MPI_GET_LIBRARY_VERSION with
1.8, it'll still run-time link with this change.
However, if an MPI program compiled using parameter name passing with
the old/incorrect parameter name ("name"), it won't be able to compile
with the new/correct parameter name ("version"). But this will only
happen for an incorrect MPI application (because the MPI-3 mandated
parameter name is "version", not "name"), so they deserve what they
get.

While testing one-sided on LANL systems I found a couple more OSC
bugs that were not caught during the initial testing:
- In the passive target code we read the read lock count as a
char instead of the intended uint32_t. This causes lock to
lockup when using shared locks after 127 iterations.
- The post code used the wrong group when trying to increment post
counters. This causes a segmentation fault.
- Both the post and wait code used the wrong check in the inner
loop leading to an infinite loop.

This commit fixes two nasty races:
- One can occur if the connection request message and connection completion
message arrive out of order. This can happen normally when adaptive routing
is used and also in a timeout situation where a UD message is lost.
- One occurs when handling an ack at the same time as we are handling the
message timeout. In this case we can not free the message or the timeout
will be operating on invalid data. This fix is a band-aid until I can come
up with a better approach. Instead of freeing the message it is marked
as inactive and the event callback is triggered immediately (this has no
affect if the callback is already active). The callback then frees the
message if it is inactive.

There are two cases that needed to be handled:

the origin data but we can not rely on the convertor to do the
unpack (see r31204).
- Both the origin and target datatypes are simple datatypes. In this
case we can use ompi_op_reduce to do the accumulation without having
to pack the origin data.
