Gilles Gouaillardet 76204dfafe coll/basic: fix segmentation fault in neighborhood collectives if the degree ...

of the topology is higher than the communicator size

It is possible to have a topology degree higher than the size of the communicator.
For example, a periodic cartesian communicator on MPI_COMM_SELF. This will leave
the neighborhood collectives with a request buffer that is too small.

This commits introduces a semantic change :
from now, c_topo must be set before invoking coll_select

The bulk of the remaining renaming changes, in one final glorious "blob". Thanks to Jeff for some help chasing down a few spots. Per chat with Jeff, we decided to cleanup a few things that were historical in nature:

Some more cleanups. Remove direct references to ORTE by changing OMPI_CAST_ORTE_NAME -> OMPI_CAST_RTE_NAME. Ensure that ORTE tools (mpirun, orted, tools) set the OPAL proc structure fields so OPAL knows what is going on and uses the correct print functions (still need to fix the problem for non-MPI apps). Properly return uint32_t from the opal utilities instead of int32_t as that is what the ORTE process name fields contain.
