Beast.Asio:

New classes:

  class async_completion:
    Helper class for implementing asynchronous initiation functions.
    See n3964:
        Library Foundations for Asynchronous Operations, Revision 1
        http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n3964.pdf

  class basic_streambuf:
    Meets the requirements of Streambuf.

  class buffered_readstream:
    Buffers a ReadStream with a ConstBufferSequence.

  class consuming_buffers:
    Adapts a BufferSequence which wraps the underlying buffer
    sequence and presents fewer bytes, with the retained bytes
    occurring at the end of the sequence.

  class handler_alloc:
    A C++ Allocator the uses asio handler allocation hooks.

  class static_streambuf:
    An implementation of the Streambuf concept that uses a
    fixed size buffer with size determined at compile-time.

  class streambuf_readstream:
    Buffers a ReadStream with a Streambuf.

New functions:

  append_buffers()
    Returns a new BufferSequence which efficiently concatenates
    two or more buffer sequences together.

  prepare_buffers()
    Shortens a buffer sequence. The bytes excluded are at the
    end of the underlying buffer sequence.

  boost::asio::read_until()
    A copy of boost::asio::read_until overloads, modified to work
    with a beast::asio::basic_streambuf.

Debugging:

  buffers_to_string()

    Convert a ConstBufferSequence to a human readable string
    suitable for diagnostics.

type_check.h:

  Metafunctions for checking asio concepts:
    AsyncReadStream, AsyncWriteStream
    SyncReadStream, SyncWriteStream
    ConstBufferSequence, MutableBufferSequence
    Streambuf
    Handler

Changes:

* All symbols moved up a namespace level.
* streambuf provides all move and copy special members,
  behavior of moved from objects is well-defined.

Fixes:

* Fix basic_streambuf iterator category.
