Besides the way the transport handles the stream after SASL <success/>, the SASL logic is independend from the underlying transport (BOSH, TCP, …). Hence move it up into AbstractXMPPConnection. This also has the benefit that we can make some more methods private or package-private. Also introduce XmlStringBuilder.optTextChild(), which causes some associated changes.
