Synchronize bindingRequired

Browse source 
Right after PacketReader receives the 'success' stanza, indicating
successful SASL authentication, it opens a new stream. The login
process continues in another thread and checks for bindingRequired,
which may not have been set a this point yet.

bindResourceAndEstablishSession() now waits until either the binding
feature stanza is parsed or the default packet timeout occurs.
