Merge mac_portacl.c:1.5 from HEAD to RELENG_5:

  date: 2004/12/06 19:43:45;  author: rwatson;  state: Exp;  lines: +19 -26
  Switch from using an sx lock to a mutex for the mac_portacl rule chain:
  the sx lock was used previously because we might sleep allocating
  additional memory by using auto-extending sbufs.  However, we no longer
  do this, instead retaining the user-submitted rule string, so mutexes
  can be used instead.  Annotate the reason for not using the sbuf-related
  rule-to-string code with a comment.

  Switch to using TAILQ_CONCAT() instead of manual list copying, as it's
  O(1), reducing the rule replacement step under the mutex from O(2N) to
  O(2).

  Remove now uneeded vnode-related includes.

  MFC after:      2 weeks
