    remote: Allow prefixing lines with the host index
    
    When --remote-prefix is given, each line from remote scripts will be
    prefixed with "N: ", where N is the index of that host among all the
    --remote options on the command line.
    
    * remote.h (class remote): Add an optional prefix string.
    * remote.cxx (remote::run): Set the prefix if desired.
      (stapsh::handle_poll): When using prefixes, read data line-wise.
    * session.cxx (systemtap_session): Add bool use_remote_prefix.
      (systemtap_session::parse_cmdline): Set it with --remote-prefix.
