Returning a generic would allow for List<ExtensionElement> list = stanza.getExtension("foo", "bar"); to compile (Note the we are calling getExtension(), not getExtension*s*()). Users are encouraged to use the type safe getExtension(Class<? extends ExtensionElement) variant instead. Fixes SMACK-825.
