    vboxwrapper: add a general port-forwarding mechanism · ab9b1460
    David Anderson authored
    All vbox_job.xml to specify ranges of port forwardings,
    and whether the access to the host ports is remote or local.
    This is to support MPI for Rytis.
    - the existing feature (pf_guest_port) is used only for web graphics.
      The host port is always dynamically assigned;
      there's no reason to have <pf_host_port>; I removed it from the doc.
      There's no reason to write the host port to a file; I removed that.
    - The new feature is only for fixed host ports.
    - The checkpoint file can stay the way it is.
