Sync this code a little more with what's in the Linux/atheros
reference drivers.

It doesn't yet fix aggregation throughput issues, but it provides
some handy statistics for tracking what's going on.

* add an ath_txq (hardware) counter tracking how many aggregate
  frames are pending.

* Use this instead of the overall counter (axq_depth)

* Add it to the txagg sysctl

And another temporary tinker:

* Delay scheduling the TID in ath_tx_swq() if the TID has some
  hardware queued frames. This doesn't seem to (yet) be doing
  what I would like it to be doing.

The MAC is still not being kept totally busy, especially when
TX'ing UDP traffic from a local iperf process. I'll add some
more statistics and see what's going on.
