Discovery backend structure.
A backend is the instantiation of a discovery component. When a component gets enabled for a topology, its instantiate() callback creates a backend.
hwloc_backend_alloc() initializes all fields to default values that the component may change (except "component" and "next") before enabling the backend with hwloc_backend_enable().
| void(* hwloc_backend::disable) (struct hwloc_backend *backend) | 
Callback for freeing the private_data. May be NULL.
| int(* hwloc_backend::discover) (struct hwloc_backend *backend) | 
Main discovery callback. returns > 0 if it modified the topology tree, -1 on error, 0 otherwise. May be NULL if type is HWLOC_DISC_COMPONENT_TYPE_MISC.
| unsigned long hwloc_backend::flags | 
Backend flags, as an OR'ed set of hwloc_backend_flag_e.
| int(* hwloc_backend::get_obj_cpuset) (struct hwloc_backend *backend, struct hwloc_backend *caller, struct hwloc_obj *obj, hwloc_bitmap_t cpuset) | 
Callback used by the PCI backend to retrieve the locality of a PCI object from the OS/cpu backend. May be NULL.
| int hwloc_backend::is_custom | 
Backend-specific 'is_custom' property. Shortcut on !strcmp(..->component->name, "custom"). Only the custom component should touch this.
| int hwloc_backend::is_thissystem | 
Backend-specific 'is_thissystem' property. Set to 0 or 1 if the backend should enforce the thissystem flag when it gets enabled. Set to -1 if the backend doesn't care (default).
| int(* hwloc_backend::notify_new_object) (struct hwloc_backend *backend, struct hwloc_backend *caller, struct hwloc_obj *obj) | 
Callback called by backends to notify this backend that a new object was added. returns > 0 if it modified the topology tree, 0 otherwise. May be NULL.
| void* hwloc_backend::private_data | 
Backend private data, or NULL if none.
