Bug 1299411 - Decouple Port implementation from API r=aswan Decoupled the API from the implementation. From now on it is possible to create Port instances without generating an API. This allows us to internally use Ports to pass around messages with minimal overhead (in the form of unnecessary clones of messages). This will be used by native messaging. This commit has no behavioral change, it is mostly moving around some code and storing the internal message listener in a set. MozReview-Commit-ID: 4h0LNJvTH9R
