dpif-netdev: create batch object

Browse Source 
DPDK datapath operate on batch of packets. To pass the batch of
packets around we use packets array and count.  Next patch needs
to associate meta-data with each batch of packets. So Introducing
a batch structure to make handling the metadata easier.
