allowing query statistics of HW offloaded flows.

Implement the flow get method for DPDK, to get the statistics of the
provided ufid, towards reading statistics of fully offloaded flows.

Currently HW offload is accelerating only the rule matching sequence.
Introduce a framework for offloading rule actions as a pre-step for
processing the rule actions in HW. In case of a failure, fallback to the
legacy partial offload scheme.
Note: a flow will be fully offloaded only if it can process all its
actions in HW.

Change the find method to return the whole entry of UFID-rte_flow
association instead of only the rte_flow field in it, as a pre-step
towards adding and using more fields into that map entry.

Instead of statically allocated pattern items on the stack, dynamically
allocate only the required items while parsing the matches, to simplify
the parsing and make it self-contained, without need of external types,
making it easier to support more matches in the future.

Action item data structures are pointed by rte_flow_action items.
Refactor the code to free the data structures when freeing the
rte_flow_action items, allowing simpler future actions simpler to add to
the code.

A lot of the offload implementations didn't bother to initialize the
statistics they were supposed to return. I don't know whether any of
the callers actually use them, but it looked wrong.
Found by inspection.

Flow API providers renamed to be consistent with parent module
'netdev-offload' and look more like each other.
'_rte_' replaced with more convenient '_dpdk_'.
We'll have following structure:
Common code:
lib/netdev-offload-provider.h
lib/netdev-offload.c
lib/netdev-offload.h
Providers:
lib/netdev-offload-tc.c
lib/netdev-offload-dpdk.c
'netdev-offload-dummy' still resides inside netdev-dummy, but it
makes no much sence to move it out of there.
