      ipv6: add {Read,Write}Batch methods to PacketConn · 48359f4f
      Mikio Hara authored 
      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.

      http2: fix nil dereference after Read completes with an error · 3470a06c
      Tom Bergan authored 
      Case happens if Read is called after it has already returned an error
previously. Verified that the new TestPipeCloseWithError test fails
before this change but passes after.

      internal/socket: add message IO functionality · b8b13433
      Mikio Hara authored 
      This change adds portable message IO methods of Conn, IO message and
control message types, and parse methods for the types to provide
those functionality to the ipv4 and ipv6 packages.

With this change, the ipv4 and ipv6 packages can provide low-level
(but less heap allocation and the cost of invoking system calls) API
such as read and write operations for a batch of IO messages.
