History
Adrian Chadd 548a605d0d Begin fleshing out some software queue awareness for TIM handling with 
the power save queue.

* introduce some new ATH_NODE lock protected fields, tracking the
  net80211 psq and TIM state;
* when doing buffer transitions - ie, when sending and completing
  buffers - check the state of the SWQ and update the TIM appropriately.
* when clearing the TIM bit, if the SWQ is not empty then delay clearing
  it.

This is racy, but it's no less racy than the current net80211 power
save queue management code.  Specifically, with multiple TX threads,
it's quite plausible that parallel state updates will race and the
TIM will be left in an inconsistent state.  I'll address that in
a follow-up commit.
