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 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.

Without this, an attribute copy function could return non-success, but
it would not be propagated upwards. This caused the intel
MPI_Keyval3_* tests to fail.

When you call MPI_Graph_create with a old_comm of size N, and pass
nnodes=(N=1), then the Nth proc is supposed to get MPI_COMM_NULL out.
The code in this base function didn't properly handle the proc(s) that
are supposed to get MPI_COMM_NULL out.

There are situations where coll/ml does not initialize properly. These will
eventually need to be fixed but in the meantime it is better to not always
print an error message because the collective framework can still fall back
on another collective module. This commit reduces the verbose output.

In r31071 I modified the logic to not increment the hierarchy level if
no processes were selected by that sbgp. That fixed a problem seen on
systems where we don't support process binding. The problem is there
is a case where we actually did select processes yet the number of
selected processes is 0. We need to increment the hierarchy in this case
as well.
This should fix the segmentation fault found by recent MTT runs. Once
this is committed to 1.7.5 remove the .ompi_ignore's from coll/ml and
bcol/ptpcoll. Tested with ompi-tests/ibm.

This ticket adds the following functions to the standard:
- MPI_T_cvar_get_index, MPI_T_pvar_get_index, and MPI_T_category_get_index
The ticket has passed and the functions are part of MPI-3.1 that will
be released sometime later this year. In Open MPI the functions expose
existing internal functionality so they are low-risk to add to 1.8.0. I
will leave it up to Ralph whether he wants to accept these into 1.8.

It seems we can't release accumulate buffers in completion callbacks
because the btls don't release registration resources until after the
callback has fired. The fix is to keep track of the unused buffers and
free them later. This should resolve issues when running IMB-EXT and
IMB-RMA.
