We always have hwloc xml support (now that it's built into to hwloc
...
without needing libxml2). So OPAL_HAVE_HWLOC_XML is no longer
necessary.

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

Move maffinity_base_alloc_policy and
...
maffinity_base_bind_failure_action MCA params to the hwloc base
(hwloc_base_alloc_polocy and hwloc_base_bind_failure_action). Since
these MCA parameters were never on a release branch, I'm just
moving/renaming them outright and not leaving aliases to the old
names.
Note that some upper layer needs to call
opal_hwloc_base_set_process_membind_policy() to set the
set-by-MCA-param process-wide memory affinity policy. We can't do
this automatically during hwloc_base_open() because, for reasons
described elsewhere, opal_hwloc_topology is not automatically filled
during hwloc_base_open() (in short: potential scalability issues when
launching many MPI processes simultaneously on a single machine, for
example).

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.
...
Remove the sysinfo framework as hwloc replaces that functionality.
