This change provides message IO functionality that may support the
construction of modern datagram transport protocols.
The modern datagram transport protocols on a multihomed node basically
need to control each packet path for traffic engineering by using
information belongs to network- or link-layer implementation. In
addtion, it's desirable to be able to do simultaneous transmission
across multiple network- or link-layer adjacencies wihtout any
additional cost.
The ReadBatch and WriteBatch methods of PacketConn can be used to read
and write an IO message that contains the information of network- or
link-layer implementation, and read and write a batch of IO messages
on Linux. The Marshal and Parse methods of ControlMessage can help to
marshal and parse information contained in IO messages.
Updates golang/go#3661.

Package ipv6 implements IP-level socket options for the Internet
Protocol version 6. It also provides datagram based network I/O
methods specific to the IPv6 and higher layer protocols.
Fixesgolang/go#5538.
