if_otus fixes; add fast-frames support.

Fast-frames:

* include opt_wlan.h ; tsk to not doing it earlier;
* add a tx pending tracking counter for seeing how deep
  the hardware TX queue is;
* add the frame aging code from if_ath;
* add fast-frames capability to the driver setup.

Bugs:

* free the buffers (and node references) before
  detaching net80211 state.  This prevents a use-after-free in
  the node free path where we've destroyed net80211 underneath it.
