This patch reshape the way we deal with topologies completely. Where our topologies were mainly storage components (they were not capable of creating the new communicator), the new version is built around a [possibly] common representation (in mca/topo/topo.h), but the functions to attach and retrieve the topological information are specific to each component. As a result the ompi_create_cart and ompi_create_graph functions become useless and have been removed. In addition to adding the internal infrastructure to manage the topology information, it updates the MPI interface, and the debuggers support and provides all Fortran interfaces. This commit was SVN r28687.
