This commit adds - SmackReactor / NIO - a framework for finite state machine connections - support for Java 8 - pretty printed XML debug output It also - reworks the integration test framework - raises the minimum Android API level to 19 - introduces XmppNioTcpConnection Furthermore fixes SMACK-801 (at least partly). Java 8 language features are available, but not all runtime library methods. For that we would need to raise the Android API level to 24 or higher.
