Pyatv

**Changes:**

* DNS parsing has been re-written which should be more stable
and handle more use cases
* TCP keep-alive has been added to more platforms, FreeBSD being one of them
* Player management has been totally re-written for MRP, so hopefully
play state should be more accurate now
* A delay has been added to turn\_off (MRP), so it should work again
* A heartbeat loop has been added that sends a "heartbeat" to the device
every 30s to detect connection problems
* Protobuf definitions have been further lifted to match later tvOS versions

**Notes:**

* Fixed a bug where Playing instancess were not immutable
* Push updates are only issued when something in the Playing instance changed.
Previously, unrelated changes to the device could trigger push updates with
the same content in Playing.
