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."

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).

Prevent crash at shutdown rescheduling NTP task

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.
