    PR12612: compatibility with old staprun/stapio
    
    commit 3abb860f changed the staprun<->runtime message format for
    the STP_RELOCATE message, without regard for backward compatibility
    for older/mismatching stapruns.  That leads to kernel errors and
    no kernel probes and such nonsense.  Let's change the runtime to
    interoperate both with old staprun and with the current one.
    
    * runtime/transport/symbols.c (_stp_do_relocation): Also accept
      systemtap-1.3 level relocation message, if the incoming message
      size suggests.
