Detailed Description
       There are two semantics for converting cpusets to nodesets depending on how non-NUMA machines are handled.

       When manipulating nodesets for memory binding, non-NUMA machines should be considered as having a single NUMA node. The standard conversion
       routines below should be used so that marking the first bit of the nodeset means that memory should be bound to a non-NUMA whole machine.

       When manipulating nodesets as an actual list of NUMA nodes without any need to handle memory binding on non-NUMA machines, the strict
       conversion routines may be used instead.

Function Documentation
   static inline void hwloc_cpuset_from_nodeset (hwloc_topology_ttopology, hwloc_cpuset_tcpuset, hwloc_const_nodeset_tnodeset) [static]
       Convert a NUMA node set into a CPU set and handle non-NUMA cases. If the topology contains no NUMA nodes, the machine is considered as a
       single memory node, and the following behavior is used: If nodeset is empty, cpuset will be emptied as well. Otherwise cpuset will be
       entirely filled. This is useful for manipulating memory binding sets.

   static inline void hwloc_cpuset_from_nodeset_strict (struct hwloc_topology *topology, hwloc_cpuset_tcpuset, hwloc_const_nodeset_tnodeset)
       [static]
       Convert a NUMA node set into a CPU set without handling non-NUMA cases. This is the strict variant of hwloc_cpuset_from_nodeset. It does
       not fix non-NUMA cases. If the topology contains some NUMA nodes, behave exactly the same. However, if the topology contains no NUMA nodes,
       return an empty cpuset.

   static inline void hwloc_cpuset_to_nodeset (hwloc_topology_ttopology, hwloc_const_cpuset_tcpuset, hwloc_nodeset_tnodeset) [static]
       Convert a CPU set into a NUMA node set and handle non-NUMA cases. If some NUMA nodes have no CPUs at all, this function never sets their
       indexes in the output node set, even if a full CPU set is given in input.

       If the topology contains no NUMA nodes, the machine is considered as a single memory node, and the following behavior is used: If cpuset is
       empty, nodeset will be emptied as well. Otherwise nodeset will be entirely filled.

   static inline void hwloc_cpuset_to_nodeset_strict (struct hwloc_topology *topology, hwloc_const_cpuset_tcpuset, hwloc_nodeset_tnodeset)
       [static]
       Convert a CPU set into a NUMA node set without handling non-NUMA cases. This is the strict variant of hwloc_cpuset_to_nodeset. It does not
       fix non-NUMA cases. If the topology contains some NUMA nodes, behave exactly the same. However, if the topology contains no NUMA nodes,
       return an empty nodeset.
