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.

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.

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

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.

When you call MPI_Graph_create with a old_comm of size N, and pass

The mapping is not backed by any file; the fd and offset arguments are ignored.
Mac:
Map anonymous memory not associated with any specific file. The offset argument is
ignored. Mac OS X specific: the file descriptor used for creating MAP_ANON regions
can be used to pass some Mach VM flags, and can be specified as -1 if no such flags
are associated with the region
FreeBSD:
Map anonymous memory not associated with any specific file. The file

There are situations where coll/ml does not initialize properly. These will
