api: packet: ones complement sum
Added packet metadata for ones complement sum over
packet data. Some NICs calculate the sum during packet
input (at least for IP fragments) and store the value
into the packet descriptor. This offloads L4 checksum
calculation for IP fragments as SW does not need sum
all payload data, but just combine pre-calculated
sums from packet descriptors and remove extra header fields
from the sum.

linux-gen: packet: dummy ones complement implementation
Added dummy implementation of ones complement calls. Linux
generic implementation does not calculate the sum for all
incoming packets as it would be wasteful in SW. It's better
to wait until application asks it with odp_chksum_ones_comp16().
Later on, the sum could be stored into the packet header,
if we found a way to get it from the HW.

validation: packet: add call to ones complement
Call ones complement function. Actual validation of
correctness of the sum is to be done, when an implementation
exist which sets the sum on packet input.
