Title: Adding PacketOut for writing ARP packets.

This is the initial work on making a PacketOut class to write packets to a String, atm only covering ARP. Some ARP related functions were also added to PacketIn.

It currently only uses struct packet_info, rather than struct buffer and struct packet_in as in PacketIn.
