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.

Add the asio::spawn() function, a high-level wrapper for running
stackful coroutines. It is based on the Boost.Coroutine library.
Here is an example of its use:
asio::spawn(my_strand, do_echo);
// ...
void do_echo(asio::yield_context yield)
{
try
{
char data[128];
for (;;)
{
std::size_t length =
my_socket.async_read_some(
asio::buffer(data), yield);
asio::async_write(my_socket,
asio::buffer(data, length), yield);
}
}
catch (std::exception& e)
{
// ...
}
}
The first argument to asio::spawn() may be a strand, io_service or
completion handler. This argument determines the context in which the
coroutine is permitted to execute. For example, a server's per-client
object may consist of multiple coroutines; they should all run on the
same strand so that no explicit synchronisation is required.
The second argument is a function object with signature (**):
void coroutine(asio::yield_context yield);
that specifies the code to be run as part of the coroutine. The
parameter yield may be passed to an asynchronous operation in place of
the completion handler, as in:
std::size_t length =
my_socket.async_read_some(
asio::buffer(data), yield);
This starts the asynchronous operation and suspends the coroutine. The
coroutine will be resumed automatically when the asynchronous operation
completes.
Where a completion handler signature has the form:
void handler(error_code ec, result_type result);
the initiating function returns the result_type. In the async_read_some
example above, this is std::size_t. If the asynchronous operation fails,
the error_code is converted into a system_error exception and thrown.
Where a completion handler signature has the form:
void handler(error_code ec);
the initiating function returns void. As above, an error is passed back
to the coroutine as a system_error exception.
To collect the error_code from an operation, rather than have it throw
an exception, associate the output variable with the yield_context as
follows:
error_code ec;
std::size_t length =
my_socket.async_read_some(
asio::buffer(data), yield[ec]);
**Note: if asio::spawn() is used with a custom completion handler of
type Handler, the function object signature is actually:
void coroutine(asio::basic_yield_context<Handler> yield);

Add the asio::use_future special value, which adds first-class support
for returning a C++11 std::future from an asynchronous operation's
initiating function.
To use asio::use_future, pass it to an asynchronous operation instead of
a normal completion handler. For example:
std::future<std::size_t> length =
my_socket.async_read_some(my_buffer, asio::use_future);
Where a completion handler signature has the form:
void handler(error_code ec, result_type result);
the initiating function returns a std::future templated on result_type.
In the above example, this is std::size_t. If the asynchronous operation
fails, the error_code is converted into a system_error exception and
passed back to the caller through the future.
Where a completion handler signature has the form:
void handler(error_code ec);
the initiating function returns std::future<void>. As above, an error
is passed back in the future as a system_error exception.

r84314 | chris_kohlhoff | 2013-05-17 13:07:51 +1000 (Fri, 17 May 2013) | 27 lines
Add a new handler hook called asio_handler_is_continuation.
Asynchronous operations may represent a continuation of the asynchronous
control flow associated with the current handler. Asio's implementation
can use this knowledge to optimise scheduling of the handler.
The asio_handler_is_continuation hook returns true to indicate whether a
completion handler represents a continuation of the current call
context. The default implementation of the hook returns false, and
applications may customise the hook when necessary. The hook has already
been customised within Asio to return true for the following cases:
- Handlers returned by strand.wrap(), when the corresponding
asynchronous operation is being initiated from within the strand.
- The internal handlers used to implement the asio::spawn() function's
stackful coroutines.
- When an intermediate handler of a composed operation (e.g.
asio::async_read(), asio::async_write(), asio::async_connect(),
ssl::stream<>, etc.) starts a new asynchronous operation due to the
composed operation not being complete.
To support this optimisation, a new running_in_this_thread() member
function has been added to the io_service::strand class. This function
returns true when called from within a strand.

Add generic socket protocols and converting move constructors.
Four new protocol classes have been added:
- asio::generic::datagram_protocol
- asio::generic::raw_protocol
- asio::generic::seq_packet_protocol
- asio::generic::stream_protocol
These classes implement the Protocol type requirements, but allow the
user to specify the address family (e.g. AF_INET) and protocol type
(e.g. IPPROTO_TCP) at runtime.
A new endpoint class template, asio::generic::basic_endpoint, has been
added to support these new protocol classes. This endpoint can hold any
other endpoint type, provided its native representation fits into a
sockaddr_storage object.
When using C++11, it is now possible to perform move construction from a
socket (or acceptor) object to convert to the more generic protocol's
socket (or acceptor) type. If the protocol conversion is valid:
Protocol1 p1 = ...;
Protocol2 p2(p1);
then the corresponding socket conversion is allowed:
Protocol1::socket socket1(io_service);
...
Protocol2::socket socket2(std::move(socket1));
For example, one possible conversion is from a TCP socket to a generic
stream-oriented socket:
asio::ip::tcp::socket socket1(io_service);
...
asio::generic::stream_protocol::socket socket2(std::move(socket1));
The conversion is also available for move-assignment. Note that these
conversions are not limited to the newly added generic protocol classes.
User-defined protocols may take advantage of this feature by similarly
ensuring the conversion from Protocol1 to Protocol2 is valid, as above.
As a convenience, the socket acceptor's accept() and async_accept()
functions have been changed so that they can directly accept into a
different protocol's socket type, provided the protocol conversion is
valid. For example, the following is now possible:
asio::ip::tcp::acceptor acceptor(io_service);
...
asio::generic::stream_protocol::socket socket1(io_service);
acceptor.accept(socket1);
