  MPI Standard states:
  MPI_PROC_NULL is a valid target rank in all MPI RMA communication calls. The effect
  is the same as for MPI_PROC_NULL in MPI point-to-point communication. After any RMA
  operation with rank MPI_PROC_NULL, it is still necessary to finish the RMA epoch with the
  synchronization method that started the epoch.

  In the current design, both MPI_Win_lock and MPI_Win_unlock do not comply with the standard, e.g.
  if MPI_PROC_NULL is passed in as the target_rank of MPI_Win_lock or MPI_Win_unlock, without the
  fix, the job will be terminated with segfault.

The following changes apply only to the PAMId layer
 - provided MPID_Win_set_info and MPID_Win_get_info functions
 - redesigned the window creation.The change is to support new window creation
   functions introduced in MPI 3.0.
 - updated pscw, MPIDI_WinCtrlSend etc. to reflect the change made in
   MPI_Group_incl().

The following changes were made after a code review
 - added a comment for zero_req in mpidi_onesided.h
 - replaced "pami_task_t peer" "int rank"  in MPIDI_WinCtrlSen()

Delete code for zero-size data transfer in packet handlers
of Put/Accumulate/Accumulate_Immed/Get_AccumulateResp/GetResp/
LockPutUnlock/LockAccumUnlock, because they are redundant.

(Note that packet handlers of LockPutUnlock and LockAccumUnlock
are for single operation optimization in passive RMA)

Zero-size data transfer has already been handled when issuing
RMA operations (L146, L258, L369 in src/mpid/ch3/src/ch3u_rma_ops.c
and L50 in src/mpid/ch3/src/ch3u_rma_acc_ops.c). RMA operation
routines will directly exit if data size is zero.

MPIU_Assert at L2311 checks if rma_ops_list is empty before exiting
MPIDI_Win_flush. It causes /test/mpi/threads/rma/multirma to fail
because while one thread is executing the loop of poking progress
engine at L2293 ~ L2302, another thread may enqueue new RMA operations
to rma_ops_list.

rma_ops_list has already been checked for empty before exiting
MPIDI_CH3I_Do_passive_target_rma (L2724) to ensure that all enqueued
operations are issued out, therefore it does not need to be checked
again here.

Drop payload into a union paired with a double, and payload will end up
double-aligned.  Can't use an anonymous union, though: that's c11.

named-union requires updating any place that used payload.  There aren't too
many, though.

MPIR_Type_get_contig_blocks is buggy for certain datatypes (example:
HDF5 multi-dataset IO generated type results in a contig block count of
5 billion.  should be more like 200).  Nothing uses this function except
ROMIO's flattening code.  I'd like to see profiling suggesting the count
of contiguous blocks is a profitable short-circuit before spending a ton
of time debugging it.
