Since using a pipe, as we did previously would not error the target if
the first command in the pipe fails.
It is still far from ideal, since the dot file is also generated if
the gradle command fails. At some point, this should probably become
part of gradle build step instead of shelling out to a Makefile.
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.
