Qingsi Wang ecd3054b56 Replace a broken assumption in candidate gathering for mDNS candidates.
The gathering of host candidates with mDNS names is asynchronous and its
completion can happen after a srflx candidate is gathered by the same
underlying socket. We have a broken check in UDPPort::CreateConnection()
that assumes the gathering of host and srflx candidates is sequential.

This CL also does minor refactoring and clean-up.
