session: use half-open sessions for vc establishment
Use half-open sessions to track virtual circuit connection
establishment. These sesssions can only be allocated and freed by the
thread that allocates half-open connections (main). Consequently, they
can only be freed on half-open cleanup notifications from transports.
Goal is to simplify state tracking within the session layer but it's
also a first step towards allowing builtin apps to track and cleanup
outstanding connects.
