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.

Change fc::canceled_exceptions thrown due to a socket operation being canceled into regular fc::exceptions -- we're reserving canceled_exception for canceling async tasks

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.

Add a new version of tcp_socket::connect_to() that allows you to set the source port
...
(working, but not yet useful because we'll need to set SO_REUSEADDR)
