    The transport last_time_used variable is rather useless.
    It was only used when determining if CWND needs to be updated
    due to idle transport.  However, idle transport detection was
    based on a Heartbeat timer and last_time_used was not incremented
    when sending Heartbeats.  As a result the check for cwnd reduction
    was always true.  We can get rid of the variable and just base
    our cwnd manipulation on the HB timer (like the code comment sais).
    We also have to call into the cwnd manipulation function regardless
    of whether HBs are enabled or not.  That way we will detect idle
    transports if the user has disabled Heartbeats.
