Implement a check for self.cid.nil? in Meterpreter's Channel class
in the :closed? method for compatibility with the Socket's :closed?
Touch up the Rex DNS server's stop method using this method on
pivot sockets.
Add SOL_SOCKET and SO_REUSEADDR options to the Rex UDP sockets
created by the DNS components - the server socket, as well as the
client abstraction socket.
