In order to improve revalidator performance by minimizing unnecessary
copying of data, extend netdev-offloads to support terse dump mode. Extend
netdev_flow_api->flow_dump_create() with 'terse' bool argument. Implement
support for terse dump in functions that convert netlink to flower and
flower to match. Set flow stats "used" value based on difference in number
of flow packets because lastuse timestamp is not included in TC terse dump.
Kernel API support is implemented in following patch.

All the kmap lookup operations netdev_ports_flow_del, netdev_ports_get
netdev_ifindex_to_odp_port should protected by rdlock without
affect each other in the handlers and revalidators

New module 'netdev-offload' created to manage different flow API
implementations. All the generic and provider independent code moved
there from the 'netdev' module.
Flow API providers further encapsulated.
The only function that was changed is 'netdev_any_oor'.
Now it uses offloading related hmap instead of common 'netdev_shash'.
