Now that the infrastructure is calling BTL del_procs() before the BTL
finalize(), the usnic BTL had to re-order some of its teardown
sequence to avoid assert() failing.
This is part of a larger conversation involving #4669. Since
MPI_FINALIZE and MPI_COMM_DISCONNECT currently use an
oob/grpcomm-based barrier, the usnic BTL can ''absolutely know'' that
these endpoints and procs will no longer be used. If the ORTE DPM
goes back to a PML-based barrier, the usnic BTL will need to grow more
complex teardown semantics (a la TCP socket FIN/ACK/FIN_WAIT states).

to be based on grpcomm (i.e., an out-of-band based barrier) rather
than the simplistic PML-based barrier that it currently uses.
This is pending a larger discussion with Nathan and George, but it
will allow the usnic BTL to stop assert()-failing in light of the
recent del_procs() change.
This commit was SVN r31870.
Based on a suggestion from George on #31806, use the pre-computed
sizes rather than duplicating the computation math (which may change
someday in the future).

Thus, all the cleaning should first be done in the btl_send array,
and them in the other arrays (btl_eager and btl_rdma).

This commit fixes two issues:
- This intent of the code @ bml_r2.c:486 is to prevent calling the
btl_del_procs more than once for a given proc. Gilles correctly
identified there was a problem in this code but r31786 we not the
correct fix.
- Fix a segmentation fault in r2 finalize revealed by the fact we
actually call del_procs now.

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.

Make sure to cleanup the registation cache when removing an
endpoint. This leak only affects systems with XPMEM installed.
Since this is in code specific to XPMEM not sure who could review so
sending it directly to the RM.

This commit :
- Correctly retrieve the communicator size when
checking memory and parameters
- Ensure (sendtype,sendcount) and (recvtype,recvcount)
matches and return with MPI_ERR_TRUNCATE otherwise
- Return with MPI_SUCCESS without invoking the low level
if no data is going to be transferred
- Fixes trac:4506

Deadlock when using the shmem_collect32()/shmem_collect64() routines and any of the non-root PEs pass 0 as the number of elements.
Algorithm in _algorithm_central_collector() does use 0 as a special value, and thus does not break out of the loop.

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.
