kernel - Fix kqueue panic on signal event knote

* sig_filtops filters on a process, not a file descriptor.  Remove
  the FILTEROP_ISFD flag.

  This should fix a panic when the kqueue is closed while the signal
  event is still active.

pf: Update packet filter to the version that comes with OpenBSD 4.1

    The original OpenBSD 4.1 defaults to "keep state flags S/SA" for
    all pass rules. In contrast to that we default to "no state". As
    in earlier verions of pf in DragonFly the default keep-state
    policy can still be set with the keep-policy option (e.g. "set
    keep-policy keep state (pickups)").

    DragonFly additions to pf have been kept: fairq support,
    pickups.
