Fix a yield-during-catch bug in udp_socket, and add a shared_ptr version of udp_socket::send_to() which will avoid reading from uninitialized memory in the face of cancellation.

Fix more locations where we were making boost::asio calls with buffers declared on the stack which could cause problems when the calling tasks were canceled.

Allow us to safely cancel tasks that are executing asynchronous network reads
...
and writes. This was previously unsafe because we almost always passed read/write
buffers to boost that were on the stack. Canceling the task deleted the stack and
therefore the buffer, but couldn't reliably prevent boost from writing to the buffer
if data came in after the cancel. This commit adds variants of the read and write
functions that take a shared_ptr<char> instead of a raw char* as the buffer, and
these variants will ensure the shared_ptr will outlive the boost::asio read/write.

Revert "Instead of canceling the read_loop, close the socket and wait for the read_loop to finish as a result. This prevents the receive_from from writing into the buffer (which is on the stack!) after the task is canceled. This caused nasty intermittent exception stack unwind errors."

Wrap boost::exception with fc::exception in fc::ip::endpoint::from_string()
...
Restructure udp_socket::receive_from() to something functionally identical, but has one less exception handler on the stack which I hope would make it easier to debug strange exception-handling errors encountered on win64

Dequeue a thread from a blocking promise's notify list when the all the thread's tasks that are waiting on that promise are canceled. This prevents a crash when the promise is fulfilled after the thread is destroyed.
...
Re-organize read-loop execution to avoid crashes in read_loop on Win32 when ntp object destructs. Call quit on ntp_thread when ntp object destructs to free up thread (eventually we need to make fc::threads call quit in their destructor, but more work is required to make that work properly).
~fc::udp_socket now closes socket on destruction (consider doing this for tcp sockets as well).

Set canceled flag in task's context object so that we cancel out of active tasks when they try to resume. Wrap a try-catch block around tcp and udp resolve requests to convert any non-fc exceptions to fc exceptions. Minor change to clarify design intent that request_time_task should always be running in _ntp_thread.

Bugfix: Incorrect ordering of newline and carriage return in HTTP server
...
The HTTP server was printing "\n\r" at the end of lines in the response
headers, which is invalid and caused some HTTP clients to detect an end
to the headers after the first header line.
The server now prints the proper "\r\n" sequence, which is parsed
correctly by clients.
