  Log:
  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.
