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.
Also add minidns-core as dependency to smack-core. This requires
increasing the minimum required Android SDK level to 9, as this is
what MiniDNS requires.
in case hostAddresses was null, the isEmpty() check before the log()
invocation would throw an NPE. Thanks to Ingo Bauersachs for reporting
this.
Fixes SMACK-788.
