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 and RawConn 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
and Header can help to marshal and parse information contained in IO
messages.
Updates golang/go#3661.

This change adds support for Solaris.
To read and write IPv4 ancillary data using ControlMessage, ipv4 pacakge
requires https://go-review.googlesource.com/30171/
Note: Unlike other platforms, Solaris seems to have a few restrictions
on ICMP property access via raw IP sockets. At least applications are
prohibited from using IP_RECVTTL option for ICMP transport.
Fixesgolang/go#17323.
