dhcp: Add DHCP discover sending
On starting the client, use the supplied interface mac address and create a transaction id. Puzzle together an IP/UDP/DHCP Discover message, compute checksums and send it out as a raw packet. Create an additional function that constructs default options common to all DHCP messages. Set the DHCP Client ID option as noticed by Grant Erickson in ConnMan commit b18d9798b3a0ae46ed87d6d2be8d5a474bf3ab1e: "Some Internet gateways and Wi-Fi access points are unhappy when the DHCPv4 client-id option (61) is missing and will refuse to issue a DHCP lease."
