59066d80b2 Add custom I/O executor support to I/O objects.
All I/O objects now have an additional Executor template parameter. This
template parameter defaults to the asio::executor type (the polymorphic
executor wrapper) but can be used to specify a user-defined executor
type.

I/O objects' constructors and functions that previously took an
asio::io_context& now accept either an Executor or a reference to a
concrete ExecutionContext (such as asio::io_context or
asio::thread_pool).

One potential point of breakage in existing user code is when reusing an
I/O object's io_context for constructing another I/O object, as in:

    asio::steady_timer my_timer(my_socket.get_executor().context());

To fix this, either construct the second I/O object using the first I/O
object's executor:

    asio::steady_timer my_timer(my_socket.get_executor());

or otherwise explicitly pass the io_context:

    asio::steady_timer my_timer(my_io_context);

b5b17a67f0 Use std::string_view for C++17 or later, and std::experimental::string_view for C++14.
Define the preprocessor macro BOOST_ASIO_DISABLE_STD_STRING_VIEW to
force the use of std::experimental::string_view (assuming it is
available) when compiling in C++17 mode.

e746865f78 Initial port to Windows Runtime.
This change adds limited support for using Asio with the Windows
Runtime. It requires that the language extensions be enabled. Due to the
restricted facilities exposed by the Windows Runtime API, the port comes
with the following caveats:

* The core facilities such as the io_service, strand, buffers, composed
  operations, timers, etc., should all work as normal.

* For sockets, only client-side TCP is supported.

* Explicit binding of a client-side TCP socket is not supported.

* The cancel() function is not supported for sockets. Asynchronous
  operations may only be cancelled by closing the socket.

* Operations that use null_buffers are not supported.

* Only tcp::no_delay and socket_base::keep_alive options are supported.

* Resolvers do not support service names, only numbers. I.e. you must
  use 80 rather than http.

* Most resolver query flags have no effect.

d41d2d15e9 * Add support for the fork() system call. Programs that use fork must call
io_service.notify_fork() at the appropriate times. Two new examples have been
  added showing how to use this feature. Refs #3238, #4162.

* Clean up the handling of errors reported by the close() system call. In
  particular, assume that most operating systems won't have close() fail with
  EWOULDBLOCK, but if it does then set blocking mode and restart the call. If
  any other error occurs we assume the descriptor is closed. Refs #3307.

* EV_ONESHOT seems to cause problems on some versions of Mac OS X, with the
  io_service destructor getting stuck inside the close() system call. Use
  EV_CLEAR instead. Refs #5021.

* Include function name in exception what() messages.

* Fix insufficient initialisers warning with MinGW.

* Make the shutdown_service() member functions private.

* Add archetypes for testing socket option functions.

* Add missing lock in signal_set_service::cancel().

* Fix copy/paste error in SignalHandler example.

* The signal header needs to be included in signal_set_service.hpp so that we
  can use constants like NSIG and SIGRTMAX.

* Don't use Boost.Thread's convenience header. Use the header file that is
  specifically for the boost::thread class instead.

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.
