Subject: Fix client side core dump when disconneced unexpectedly:  void
 qpid::client::SessionCore::invariant() const: Assertion

Minor items:
src/qpid/broker/Queue.cpp: info log for each message dispatched.
src/qpid/broker/SessionHandler.cpp: check attached in handleOut()
src/qpid/sys/Dispatcher.cpp: use polymorphic_downcast to catch cast errors in debug builds.
src/qpid/client/SessionCore.cpp: fix incorrect asserts
src/qpid/client/Message.h: convenience constructor parameters
