identified by the intel test suite.

the case fix in ompi_osc_base_process_op in r31204.
There are two cases that needed to be handled:
- The target is a simple datatype (contiguous block of a primitive
type) but the origin is not. In this case we still need to pack
the origin data but we can not rely on the convertor to do the
unpack (see r31204).
- Both the origin and target datatypes are simple datatypes. In this
case we can use ompi_op_reduce to do the accumulation without having
to pack the origin data.

Fixed two bugs:
- Use module->comm NOT comm to get the CID for the shared memory backing
file. This fixes the case where there are multiple shared memory windows
at the same time.
- Remember to unlink the shared memory backing file.

This commit fixes two bugs:
- We were not correctly setting the lock type in the outstanding lock
for lock_all. This caused undefined behavior.
- flush_all was incorrectly checking for comm size - 1 lock acks but
comm size flush acks. This is the reverse of what was intended.

In most cases, bad messages received by the connectivty checker are
just dropped. However, in one specific code path, a bad packet caused
an abort. Doh!
This commit does two things:
1. Improve verbose messages for all these cases
1. Simply drop incoming messages that cannot be identified as ACKs or PINGs

It is possible to get into a situation where a small accumulate operation
can not be completed because a large accumulate operation holds the lock.
In this case we may return from wait/flush/etc before the operation is
complete. To handle this case increment the expected incoming fragment
count when queuing an accumulate operation and increment the incoming
fragment count after processing the accumulate operation.

of the primitive datatype
In this case we can not use the convertor to run the accumulate operation
since the datatype is a more or less a primitive type.

The following Trac tickets were found above:
Ticket 4449 --> https://svn.open-mpi.org/trac/ompi/ticket/4449
This commit fixes two issues:
- osc/rdma: The target side of an accumulate was using the target datatype
in the receive to the packed buffer. This was conflicting with the way
the reduction is done into the target buffer. Changed the receive to use
the primitive datatype.
- osc/base: The copy table was completely wrong. Fixed the table to match
the underlying datatypes (which are opal not ompi datatypes).
- osc/base: There is a problem using the optimized description. Fall back
on using the non-optimized description until we can understand what is
going wrong.

results
The code to handle completion messages did not correctly increment the
number of expected messages. This could cause wait to return before all
incoming messages are complete.
I also added a check to ensure that start returns an error if we are in
a passive access epoch.

ROMIO code assumes all processes will use the same ROMIO driver. we
were not reaching the "find a common file system" logic when NFS was
enabled, everyone stat-ed the file system without errors, but some
processees found a different file system (like if some processes are
writing to NFS and others to UFS)

This commit adds large datatype description support to the osc/rdma
component. Support is provided by an additional send/recv of the datatype
description if the description does not fit in an eager buffer. The
code is designed to require minimal new code and not for speed. We
consider this code path to be a slow path.

When we are only using local ranks basesmuma needs to provide an allreduce
function for both large and small message or else the coll/ml selection
logic will fail. In the future this logic should probably be updated to
just disable allreduce in coll/ml instead of disabling coll/ml. For now
it should be correct to say the basesmuma allgather works for larger
messages.

a hierarchy actually matches a bcol that is in use.
There was a bug in one of the paths to calculate the ml buffer size. I fixed
the bug and squashed all the paths together to avoid further issues (the
result was correct in another path that calculated the same value).
Additionally, the i_hier was being used as the bcol_index. This is not
correct in a couple of cases so I added a variable to keep track of the
real bcol_index.

This case is correctly handled by coll/ml so remove the check that diables
coll/ml in the not bound case.

This commit was SVN r31188.
This patch fixes two leaks:
- Fix typo in fallback collective code that caused coll/ml to retain
the ibcast module twice but only release it once. One of those ibcast
saves was supposed to be bcast.
- Do not check for module initialization in the module destructor. It
is possible to destruct a module that is partially setup.
