The cited commit failed partial matching of TCP/UDP port matching,
preventing such offload of supporting HWs. Remove this failure.

For OVS rule of the form "eth type is 0x1234 / end", rule is offloaded
in the form of "eth / end", which is incorrect. Fix it.

'dpif_probe_feature'/'revalidate' doesn't free the 'dp_extra_info'

initialize the value to avoid printing/freeing of random memory.

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.

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.

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.

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.
