Introduce a set of bitmap operation helpers for netdev features, then we can use them to replace the logical operation with them.

The implementation of these helpers are based on the old prototype of netdev_features_t is still u64. I will rewrite them on the last patch, when the prototype changes.

To avoid interdependencies between netdev_features_helper.h and netdevice.h, put the helpers for testing feature is set in the netdevice.h, and move advandced helpers like netdev_get_wanted_features() and netdev_intersect_features() to netdev_features_helper.h.
