  MFC:
    First step in removing welding between ipfw(4) and dummynet.
  
    o Do not use ipfw_insn_pipe->pipe_ptr in locate_flowset(). The
      _ipfw_insn_pipe isn't touched by this commit to preserve ABI
      compatibility.
    o To optimize the lookup of the pipe/flowset in locate_flowset()
      introduce hashes for pipes and queues:
      - To preserve ABI compatibility utilize the place of global list
        pointer for SLIST_ENTRY.
      - Introduce locate_flowset(queue nr) and locate_pipe(pipe nr).
    o Rework all the dummynet code to deal with the hashes, not global
      lists. Also did some style(9) changes in the code blocks that were
      touched by this sweep:
      - Be conservative about flowset and pipe variable names on stack,
        use "fs" and "pipe" everywhere.
      - Cleanup whitespaces.
      - Sort variables.
      - Give variables more meaningful names.
      - Uppercase and dots in comments.
      - ENOMEM when malloc(9) failed.
