Move SASL logic into AbstractXMPPConnection

Browse source 
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.
