Implement XEP-0198: Stream Management (client only) (#99)

* Some features can be available with different namespaces (e.g. SM)

* Provide static functions to convert between strings and stream errors

Stream management will reuse this for <failed />.

* [travis] test builds using clang

* Implement XEP-0198: Stream Management (client only)

* QXmppOutgoingClient: Move private methods to QXmppOutgoingClientPrivate
