    logging: add experimental --debug add-prefix
    
    It changes logging output so that:
    
    - the log prefix is included on debug lines
    
    - the state's name is included in all lines
    
    For instance:
    
    | "westnet-eastnet" #1 MAIN_I3: inserting event EVENT_v1_RETRANSMIT, timeout in 0.500000 seconds for #1
    "westnet-eastnet" #1 MAIN_I3: STATE_MAIN_I3: sent MI3, expecting MR3
    
    Since it isn't part of --debug all it doesn't affect tests.
