Subject: Preparation for session thread safety overhaul:  - simplified
 SessionState, responsibility for protocol states now in Handlers  -
 qpid::RefCounted, qpid::intrusive_ptr reference counting support.  - build
 boost unit tests as single exe, speeds up testing.  - fixed leak in
 AsynchIOAcceptor.cpp
