This commit fixes a bug that can occur on Cray Gemini networks. If
multiple registrations are used for the local state then we looks the
atomicity guarantees. To avoid issues like this use only a single
registration handle for all local state on a node.

This commit fixes the following:
- CIDs 1328491, 1328492: Dead code caused by typos in a prior
commit.
- Fix the calculation of dynamic memory regions. This was causes
incorrect RMA range errors when accessing the last partial page of
an attachment.
- Fix a SEGV when using dynamic memory windows with local state (all
processes on the same node).

When using dynamic memory windows the displacement becomes a
pointer. Since the high bit may be set on valid pointers on some
platforms the check for disp > 0 is invalid. This commit adds the
window flavor to ompi_win_t and disables the displacement check when
operating on dynamic memory windows.

This commit fixes a bug that occurs when a post message comes in when
sending complete messages or while waiting for all outgoing messages
to flush. In that case the post message might get incorrecly
associated with the ending sync object.

This commit fixes several bugs in the osc/rdma component:
- Complete aggregated requests immediately. Completion of RMA
requests indicates local completion anyway. This fixes a hang in
the c_reqops test.
- Correctly mark Rget_accumulate requests.
- Set the local base flag correctly on the local peer.
- Clear or set the no locks flag on the window if the value is
changed by MPI_Win_set_info.
- Actually update the target when using MPI_OP_REPLACE.

currently, MPI fails with MPI_ERR_ARG. This is counter intuitive since
MPI_IN_PLACE is a legitimate parameter. MPI_IN_PLACE might not be correctly
implemented by all the non blocking modules (libnbc, ...) so fail with
MPI_ERR_INTERN for the time being.
This commit changes the priority of mtl components to be relative to
pml/ob1 and updates the mtl interface to expose this priority. cm now
sets its own priority based on the priority of the selected mtl
component.

The mca_base_select function uses returned priorities to select the
best component/module. This priority may be of use to the caller so
pass that information back in an optional argument. If the priority is
not needed pass NULL.

This commit removes code that checks the ob1 priority vs the previous
priority. The previous priority is meaningless here and may only cause
ob1 to disable itself when it shouldn't.

This patch removes a priority check that disables cm if the previous
pml had higher priority. The check was incorrect as coded and is
unnecessary as we finalize all but one pml anyway.
