Christopher Kohlhoff 7139b456d2 Changes for asio version 1.5.0:
* Added support for timeouts on socket iostreams, such as
  ip::tcp::iostream. A timeout is set by calling expires_at() or
  expires_from_now() to establish a deadline. Any socket operations
  which occur past the deadline will put the iostream into a bad state.

* Added a new error() member function to socket iostreams, for
  retrieving the error code from the most recent system call.

* Added a new basic_deadline_timer::cancel_one() function. This function
  lets you cancel a single waiting handler on a timer. Handlers are
  cancelled in FIFO order.

* Added a new transfer_exactly() completion condition. This can be used
  to send or receive a specified number of bytes even if the total size
  of the buffer (or buffer sequence) is larger.

* Added new free functions connect() and async_connect(). These
  operations try each endpoint in a list until the socket is
  successfully connected.

* Extended the buffer_size() function so that it works for buffer
  sequences in addition to individual buffers.

* Added a new buffer_copy() function that can be used to copy the raw
  bytes between individual buffers and buffer sequences.

* Added new non-throwing overloads of read(), read_at(), write() and
  write_at() that do not require a completion condition.

* Added friendlier compiler errors for when a completion handler does
  not meet the necessary type requirements. When C++0x is available
  (currently supported for g++ 4.5 or later, and MSVC 10), static_assert
  is also used to generate an informative error message. Checking may be
  disabled by defining BOOST_ASIO_DISABLE_HANDLER_TYPE_REQUIREMENTS.

* Made the is_loopback(), is_unspecified() and is_multicast() functions
  consistently available across the ip::address, ip::address_v4 and
  ip::address_v6 classes. Refs #3939.

* Added new non_blocking() functions for managing the non-blocking
  behaviour of a socket or descriptor. The io_control() commands named
  non_blocking_io are now deprecated in favour of these new functions.

* Added new native_non_blocking() functions for managing the
  non-blocking mode of the underlying socket or descriptor. These
  functions are intended to allow the encapsulation of arbitrary
  non-blocking system calls as asynchronous operations, in a way that is
  transparent to the user of the socket object. The functions have no
  effect on the behaviour of the synchronous operations of the socket or
  descriptor. Refs #3307.

* Added the io_control() member function for socket acceptors.
  Refs #3297.

* For consistency with the C++0x standard library, deprecated the
  native_type typedefs in favour of native_handle_type, and the native()
  member functions in favour of native_handle().

* Added a release() member function to posix descriptors. This function
  releases ownership of the underlying native descriptor to the caller.
  Refs #3900.

* Added support for sequenced packet sockets (SOCK_SEQPACKET).

* Added a new io_service::stopped() function that can be used to
  determine whether the io_service has stopped (i.e. a reset() call is
  needed prior to any further calls to run(), run_one(), poll() or
  poll_one()).

* Reduced the copying of handler function objects.

* Added support for C++0x move construction to further reduce copying of
  handler objects. Move support is enabled when compiling in -std=c++0x
  mode on g++ 4.5 or higher, or when using MSVC10.

* Removed the dependency on OS-provided macros for the well-known IPv4
  and IPv6 addresses. This should eliminate the annoying "missing braces
  around initializer" warnings. Refs #3741.

* Reduced the size of ip::basic_endpoint<> objects (such as
  ip::tcp::endpoint and ip::udp::endpoint).

* Changed the reactor backends to assume that any descriptors or sockets
  added using assign() may have been dup()-ed, and so require explicit
  deregistration from the reactor. Refs #4971.

* Changed the SSL error category to return error strings from the
  OpenSSL library.

* Changed the separate compilation support such that, to use Asio's SSL
  capabilities, you should also include 'asio/ssl/impl/src.hpp in one
  source file in your program.

* Removed the deprecated member functions named io_service(). The
  get_io_service() member functions should be used instead.

* Removed the deprecated typedefs resolver_query and resolver_iterator
  from the ip::tcp, ip::udp and ip::icmp classes.

* Fixed a compile error on some versions of g++ due to anonymous enums.
  Refs #4883.

* Added an explicit cast to the FIONBIO constant to int to suppress a
  compiler warning on some platforms. Refs #5128.

* Fixed warnings reported by g++'s -Wshadow compiler option. Refs #3905.
