DHCPV4: use c++11 random number generator
This uses c++11 random number generator to replace the old
c-style random number generator.
In addition, this deletes the function DHCPMessage::
GenerateTransactionID(). Both the DHCP transaction id and
IP transaction id will be generated by the random engine in
DHCPV4.

DHCPV4: make and send dhcp packet
This adds two functions.
One is MakeRawPacket(), extracting payload from DHCPMessage
object and filling the IP and UDP headers.
Another is SendRawPacket(), sending the dhcp packet through

dhcp_client: use ByteString for hardware address
Since the hardware address of network device may contain
0 in the middle, using std::string could be ambiguous.
We change the type from std::string to shill::ByteString
to fix that.

dhcp client: add checksum computing function for class DHCPMessages
When using raw sockets for communicating with the DHCP
server, we need to fill the IP and UDP headers. Adding
checksum function allows us to fill the checksum field
in headers.

dhcp client: add socket to DHCPV4 class
The socket is used for sending and receiving DHCP messages.
We need to use raw socket before the IP is set up, so a
socket filter is needed for packet filtering.
