Smack/smack-experimental/src/main/java/org/jivesoftware/smackx/sid/element/OriginIdElement.java
Florian Schmaus 4133eb175c Replace XPP3 by XmlPullParser interface wrapping StAX and XPP3
Introducing Smack's own XmlPullParser interface which tries to stay as
compatible as possible to XPP3. The interface is used to either wrap
StAX's XMLStreamReader if Smack is used on Java SE, and XPP3's
XmlPullParser if Smack is used on on Android.

Fixes SMACK-591.

Also introduce JUnit 5 and non-strict javadoc projects.
