Ralph Castain 51129cc2a8 If built without hwloc xml support, we cannot currently pass the local topology from the daemon to an MPI app. This makes it impossible to set affinity, for example. In this case, have the app get its own copy of the topology at startup. ...

For safety sake, protect hwloc-based affinity modules from NULL topology

Per the RFC from Jeff, move hwloc from opal/mca/common to its own static framework ala libevent. Have ORTE daemons collect the topology info at startup and, if --enable-hwloc-xml is set, send that info back to the HNP for later use. The HNP only retains unique topology "templates" to reduce memory footprint. Have the daemon include the local topology info in the nidmap buffer sent to each app so the apps don't all hammer the local system to discover it for themselves.
