45da311473 osc/rdma: fix hang when performing large unaligned gets 
This commit adds code to handle large unaligned gets. There are two
possible code paths for these transactions:

 1) The remote region and local region have the same alignment. In
 this case the get will be broken down into at most three get
 transactions: 1 transaction to get the unaligned start of the region
 (buffered), 1 transaction to get the aligned portion of the region,
 and 1 transaction to get the end of the region.

 2) The remote and local regions do not have the same alignment. This
 should be an uncommon case and is not optimized. In this case a
 buffer is allocated and registered locally to hold the aligned data
 from the remote region. There may be cases where this fails (low
 memory, can't register memory). Those conditions are unlikely and
 will be handled later.

5e2a2c0755 BufFix for coll/hcoll: coll_request must be set to ACTIVE when alloced 
If the state of the request is not set to OMPI_REQUEST_ACTIVE
       then MPI_Test would immediately signal such request completed
       while hcoll may still be working on it.

49d2f44b97 osc/rdma: use correct endpoint for local state 
If atomics are not globally visible (cpu and nic atomics do not mix)
then a btl endpoint must be used to access local ranks. To avoid
issues that are caused by having the same region registered with
multiple handles osc/rdma was updated to always use the handle for
rank 0. There was a bug in the update that caused osc/rdma to continue
using the local endpoint for accessing the state even though the
pointer/handle are not valid for that endpoint. This commit fixes the
bug.

Fixes open-mpi/ompi#1241.

b921831f2b ompi/datatype: make datatype pack thread safe 
This commit makes ompi_datatype_get_pack_description thread safe. The
call is used by osc/pt2pt to send the packed description to remote
peers. Before this commit if MPI_THREAD_MULTIPLE is enabled and the
user uses MPI_Put, MPI_Get, etc we could hit a race where multiple
threads attempt to store the packed description on the datatype. Since
the code in question is not performance-critical the threading fix
uses opal_atomic_* calls instead of bothering with OPAL_THREAD_*.

6180386bea osc/rdma: disable put aggregation when using threads 
Optimizing put aggregation in the presence of threads will require a
redesign of the code. For now just ensure that put aggregation is
turned off when MPI_THREAD_MULTIPLE is enabled.
