Free closed peer connections and data channel observers - #2

Port the leak fixes from devopvoid/webrtc-java@8b77ec8 (#283) that apply to this data-channel-only fork: - RTCPeerConnection.close() cleared the Java handle but never released the reference createPeerConnection() had handed to Java, so every closed connection leaked the native PeerConnection and what it owned. - RTCDataChannel.registerObserver() allocated a native observer and never kept it, so unregisterObserver() could not free it. Each one leaked along with the JNI global reference to the Java observer, which kept the whole closed Java channel reachable. The observer is now stored in an observerHandle field and freed when it is replaced, unregistered, or the channel is disposed. - The data channel observer drops a callback instead of crashing when its thread can no longer attach to the JVM, during shutdown. The ReplaceNativeObserver/ClearNativeObserver helpers come from the same upstream commit.
