Todd Kordenbrock 42a871efd4 This commit fixes trac:4662 - "Portals4/MTL hangs in c_get_accumulate test". ...

- Portals4/OSC was unable to acquire an exclusive lock due to an invalid
local address in the atomic operation.  This caused the reported hang.
- After fixing the hang, the test continued to fail because
ompi_datatype_is_contiguous_memory_layout() reports that MPI_EMPTY (the
origin datatype) is noncontiguous and Portals4/OSC does not support
noncontiguous datatypes at this time.  However, in this case the origin
count is zero so contiguous/noncontiguous is irrelevant.  Now we skip
the contiguous check if the count is zero.

request

Revert r32082 and r32070 - the developer's conference has decided to go a different direction on the threaded progress effort. This will involve some degree of prototyping to understand the tradeoffs prior to making a final design decision, and so we'll hold off on the final change until that is completed.

runtime

Revert r32222, r32210, and r32203 as they created a problem when daemon collectives did not involve app procs on every node. Instead, modify the ompi/mca/rte/orte/rte_orte.h to add a new function that allows apps to request new daemon collective ids for use in barrier and modex operations. This will only appear in ORTE-based installations, but it is only being used by a couple of researchers at the moment.
